Before proceeding with any Kidde system design, installation, or maintenance procedure, the requirements of this manual must be fully understood. Components not described in this manual are not recognized by Kidde Fire Systems as system compo- nents and must NOT be used in the Industrial Dry Chemical Sys- tem. The Kidde Industrial Dry Chemical Fire-Suppression system is to be installed, inspected and maintained by a Kidde Fire Systems Authorized distributor, and in accordance with NFPA 17, Standard for Dry Chemical Extinguishing Systems, NFPA 33, Standard for Spray Applications Using Flammable Com- bustible Materials, and this manual. 1-3 KIDDE INDUSTRIAL FIRE-SUPPRESSION SYSTEMS The Kidde Industrial Fire-Suppression System is a fixed dry- chemical system consisting of a supply of dry chemical stored in one or more cylinder-and-valve assemblies. Each cylinder is equipped with an actuation device, which may be mechanically, electrically, or pneumatically activated. Automatic actuation is usually initiated by heat detectors that are located in the hazard area. Upon activation, the dry chemical is discharged through fixed piping and nozzles positioned through- out the protected area. 1-3.1 System Types Fixed dry-chemical systems are of two types: total-flooding and local-application. In total-flooding, a predetermined amount of dry chemical is dis- charged through fixed piping and nozzles into an enclosed space or enclosure around the hazard. Total-flooding is applicable only when the hazard is totally enclosed or when all openings sur- rounding a hazard can be closed automatically when the system is discharged. Total-flooding can be used only where no re-igni- tion is anticipated because the extinguishing action is transient. Local application differs from total-flooding in that the nozzles are arranged to discharge directly into the fire. Local application is practical in those situations where the hazard can be isolated from other hazards so that fire will not spread beyond the area protected, and where the entire hazard can be protected. The principal use of local application systems is to protect open tanks of flammable liquids. As with total-flooding systems, local appli- cation is ineffective unless extinguishment can be immediate and there are no re-ignition sources. 14 DRY-CHEMICAL FIRE SUPPRESSION Dry chemical is a mixture of powders that is used as a fire- extinguishing agent. The Kidde industrial system uses sodium- bicarbonate-base dry chemical (termed "regular dry chemical") for Class-13 (flammable liquid) and Class-C (electrical equip- ment) fires and monoammonium-phosphate base (termed .multi-purpose dry chemical") for Class-A (ordinary combus- tibles), Class-B, and Class-C fires. The dry chemicals used in the Kidde industrial system are stable at both low and high temperatures. Various additives are mixed with the base mate- rials to improve their storage; flow, and water-repellency char- acteristics. The upper storage temperature limit for the system is 120 degrees F (49 degrees C). The lower temperature limit is -40 degrees F (-40 degrees C). UL EX-2153 1-3 November 1998 Introduction Industrial Dry Chemical Dry-chemical systems are used in situations where fast extin- guishment is desired and where re-ignition sources are not present. For example, both regular and multipurpose dry-chemi- cal systems are used primarily for flammable liquid fire hazards such as dip tanks, flammable liquid storage rooms, and areas where flammable liquid spills may occur. Since dry chemical is electrically non-conductive, extinguishing systems using this agent can be used on electrical equipment that is subject to flammable liquid fires such as oil-filled circuit breakers. Dry-chemical system protection is not recommended, however, for delicate electrical equipment, such as telephone switchboards and electronic computers. Such equipment is sub- ject to damage by dry chemical deposit and, because of the in- sulating properties of the dry chemical, may require excessive cleaning to restore operation. 1-6.1 Fixed Systems Fixed systems containing multi-purpose (ABC) dry chemical are suitable for the protection of ordinary combustibles, provided that the dry chemical can reach all the burning surfaces. Dry-chemi-, cal systems should not be used for applications involving com- bustible metals such as sodium, potassium, and magnesium or for chemicals which contain their own oxygen supply. Systems should also not be designed for Class-A applications in which there is the possibility that deep-seated fires will result, prevent- ing dry-chemical access to all burning surfaces. 1-7 SYSTEM TESTING Fire and operational tests were run by discharging dry chemical through all of the nozzles listed in this manual. The discharge from each nozzle was collected and weighed to determine uni- formity of nozzle discharge. Fire extinguishing tests were run at minimum (40 degrees F/40 degrees C), normal, and maximum (120 degrees F/49 degrees C) storage temperatures of the sys- tem, together with minimum and maximum pipe lengths and pipe equivalent lengths. These tests determined the effectiveness of the system. Cycle tests were run on all components to deter- mine their operational reliability and safety. .The mixtures of powders used in dry-chemical extinguishing agents are non-toxic. However, the discharge of large amounts of dry chemical may cause temporary breathing difficulty during and immediately after discharge and may cause serious visibil- ity problems. After discharge, the dry chemical should be removed from any valu- able equipment to prevent a possible reaction between materials in the presence of moisture. Personnel in contact with the agent should remove the dry chemical from their skin with tap water. 1-5 EXTINGUISHING PROPERTIES Regular (BC) dry chemical is highly efficient in extinguishing fires in flammable liquids. It can also be used on fires involving some types of electrical equipment, such as turbine generators, oil- filled circuit breakers, and transformers. Multi-purpose (ABC) dry chemical can be used on fires involving flammable liquids, ener- gized-electrical-equipment fires, and on fires in ordinary combus- tible materials. When multi-purpose (ABC) dry chemical is discharged onto burn- ing ordinary combustibles, the decomposed monoammonium phosphate leaves a sticky residue on the burning material. This residue seals oxygen from the glowing material, thus extinguish- ing the fire and preventing re-ignition. Multi-purpose (ABC) dry chemical seldom needs the help of wa- ter to completely extinguish fires in Class-A materials. However, multi-purpose dry chemical is not effective on Class-A deep seated or burrowing fires. .When introduced into the combustion zone, dry chemical causes almost immediate flame extinguishment. Smothering, cooling, and radiation shielding contribute to the extinguishing efficiency of dry chemical, but the principal mechanism for the flame extin- guishment is the chemical chain-breaking properties of the dry chemicals. The chain-reaction theory of combustion assumes that free radi- cals are present in the combustion zone and that the reactions of these species with each other are required for continued burn- ing. The discharge of dry chemical into the flame prevents reac- tive particles from interacting and continuing the combustion chain reaction, and thus extinguishes the flame. 1-6 USES AND LIMITATIONS OF DRY-CHEMICAL SYSTEMS Regular (BC) dry chemical is primarily used to extinguish flam- mable-liquid surface fires. Because it is electrically non-conduc- tive, it can be used on flammable-liquid fires involving live electrical equipment. Due to the rapidity with which it extinguishes flame, multi-purpose (ABC) dry chemical is used on surface fires involv- ing Class-A (ordinary combustible) materials. It is important to recognize that dry chemical is considered to be a transient extinguishant and does not produce a lasting inert atmosphere above the surface of a flammable liquid, nor does it maintain a total-flooding concentration in an enclosed space. Con- sequently, its use will not result in a permanent extinguishment if .re-ignition sources, such as hot metal surfaces or persistent elec- trical arcing, are present.

When a fusible-link detector operates, the release of tension in the fusible-link cable allows the control head to actuate. A spring-loaded plunger depresses the check stem in the cylinder valve, discharging the contents of the cylinder. The control head also releases tension in .a cable to an optional tan- dem control head, causing operation of this device. The control head is equipped with a local manual-release handle integral with the control-head cover plate. To manually operate the sys- tem locally, pull the ring pin out and rotate the handle clockwise. A mechanical, remote manual release may also be used with the mechanical control head. P/N 486607 does not have a microswitch. P/N 899063 is equipped with one Form-C microswitch. P/N 899176 is equipped with two Form-C microswitches. The microswitch contacts in both control heads transfer when the control head operates. See Chapter 5 for microswitch contact ratings.

The control head is rated at 120 VAC, 10 amps nominal, or 24 VDC, 2 amps nominal. When electric power is applied to the control head, a solenoid releases a spring-loaded plunger which depresses the check stem in the cylinder valve, discharging the contents of the cylinder. The control head also releases tension in a cable to an optional tandem control head, causing operation of this device. The con- trol head is equipped with a local manual-release handle integral with the control-head cover plate. To manually operate the sys- tem locally, pull the ring pin out and rotate the handle clockwise. A mechanical, remote manual release may also be used with the electric control head. PIN 899175 is equipped with two Form-C microswitches. The microswitch contacts in the control head transfer when the con- trol head operates. One set of contacts, which is normally closed when the control head is in the set position, must be wired in series with the control-head solenoid coil to disconnect the power from the coil upon actuation. Refer to Chapter 5 for microswitch contact ratings.

In the rate-of-temperature rise principle, it is a rapid increase in temperature, resulting in a rapid pressure increase in a detec- tion-system network consisting of HADs, the pneumatic control head, and tubing, that causes the system to actuate. The HADs are connected to the control head by 1/8-inch copper tubing. When air within an HAD is heated by a fire in the pro- tected space, it expands and increases the pressure within the detector. This pressure increase is transmitted through the cop- per tubing to the pneumatic control head. When sufficient pres- sure has rapidly been built up in the entire detection-system network (HAD's, pneumatic control head, and tubing) a pressure- sensitive diaphragm in the control head's sensing chamber trips the control head's release linkage. This, in turn, releases a spring- loaded plunger which depresses the check stem in the cylinder valve and discharges the contents of the cylinder. The pneumatic control head is fitted with a vent so that small changes in pressure in the detection-system network, resulting from normal changes in temperature in the protected space, can be vented to atmosphere. However, if pressure builds up faster than it can be relieved by the vent, the pneumatic control head will actuate. This is the principle of rate-of-rise operation. UL EX-2153 2-5 November 1998 Component Descriptions Industrial Dry Chemical The sensitivity of the pneumatic control head is given in terms of the pressure differential required to trip the control-head release linkage, and this pressure differential is measured in inches of water. Pneumatic control heads used for industrial applications are set to activate at a pressure differential of 4 inches of water. The vent size is measured in terms of seconds, and the number of seconds indicate the time required for a 3-inch (water column, w.c.) pressure differential in the control head's sensing chamber to drop 2 inches (i.e., from 3 inches w.c. to 1 inch w.c.). The larger the vent size in seconds, the faster the control head will respond to temperature changes. Pneumatic control heads for industrial systems that are connected directly to HAD's use a vent size of 5 seconds. Upon actuation, the pneumatic control head also releases ten- sion in a cable to an optional tandem control head, causing op- eration of this device. The control head is equipped with a local manual-release handle integral with the control-head cover plate. To manually operate the system locally, pull the ring pin out and rotate the handle clockwise. A mechanical, remote manual re- lease may also be used with the pneumatic control head. ~ENSING ,- VENT PLUG \DIAPHRAGM CONNECTOR FOR PNEUMATIC TUBING FROM REMOTE I,I MANUAL puLL_[jcl I TO TANDEM CONTROl.

These systems use a mercury check, P/N 871346, to isolate the pneumatic tubing branch lines from each other in order to maintain the proper detection system response characteristics. The mercury check is also the interface between the pneumatic detection system (tubing and HAD's) and the pneumatic control head. The HAD's are connected to the mercury check by 1/8-inch cop- per tubing. When air within an HAD is heated by a fire in the protected space, it expands and increases the pressure in the detector. This pressure increase is transmitted through the cop- per tubing to the mercury check, and from the mercury check to the pneumatic control head. When sufficient pressure has been S rapidly built up in one detection system branch (HAD's, tubing line, mercury check, and pneumatic control head), a pressure- sensitive diaphragm in the control head's sensing chamber trips CAU11ON THE CONNECTION TO REMOTE MANUAL PULL OR TANDEM CONTROL HEAD SHALL ONLY BE MADE THROUGH THE CONTROL HEAD PORTS SHOWN IN FIGURE 2-14.

A primary control head, which may be mechanical, electric, or pneumatic, is attached to one cylinder valve. Each additional cylinder is equipped with a tandem control head. Release of cable tension from the primary control head actuates the tandem con- trol head(s), operating all cylinder valves simultaneously. The tandem control head is not equipped with an integral manual- release handle or microswitch contacts. There is no limit to the number of tandem control heads that may be used. However, there is a maximum of 30 corner pulleys and 100 It. (30.4 m) of cable between the primary and last tandem control head. NOTE: An alternative method may be used to actuate multiple cylinders in large applications. This alternative method uses the KRS-100 or KRS-700S releasing systems. Refer to Kidde Fire Systems manual P/N KRS100-001 for specific details regarding the KRS-00 actuation system, or to manual P/N 415830 for details of the KRS- 700S actuation system.

Overhead nozzles are designed to discharge a solid cone of dry chemical down onto a protected area from a fixed location above the protected area. There are two different overhead nozzles; low-overhead and high-overhead. The low-overhead nozzle, shown in Figure 2-9, uses a screen at the nozzle outlet to reduce the velocity of the dry-chemical dis- charge.

One temperature is called the rating temperature, and the other is called the maxi- mum exposure temperature. The rating temperature, which is stamped on the fusible link, is the temperature at which the link will separate when new. How- ever, continual exposure to cycling ambient temperatures may cause a degradation of the link overtime. Therefore, the fusible links must be replaced at least annually with a new link having the proper temperature rating. The maximum exposure temperature is the maximum ambient air temperature in which a fusible link may be installed. The maxi- mum air temperature at the point of link installation must not ex- ceed the maximum exposure temperature shown in the table. 2-4.3 Quartzoid-Bulb Link, PIN 260527 The quartzoid-bulb link is used in conjunction with the fusible link housing kit. The quartzoid-bulb link consists of a glass bulb, filled with liquid and a small air bubble, and a metal housing. Tempera- ture rise expands the liquid in the bulb and compresses the air bubble. When a predetermined temperature is reached, the ex- panding liquid breaks the glass bulb and allows the housing pieces to separate. Quartzoid-bulb links are available with a 500 de- grees F (260 degrees C) temperature rating. The maximum ex- posure temperature for the quartzoid-bulb link is 475 degrees F (246 degrees Q. Quartzoid bulbs to be used on industrial systems are UL listed and designated Issue B. The loop marked A" should be installed toward the control head. Quartzoid bulb links have an unlimited life expectancy before operation, and need not be changed on an annual basis. However, the local authority having jurisdiction may rule otherwise. On periodic inspection, the quartzoid bulb link must be wiped clean of grease and dirt with a clean dry cloth. UL EX-2153 2-8 November 1998 Industrial Dry Chemical Component Descriptions Figure 2-16.

Chapter 3 Design 0 I. Introduction To Design 3-1 INTRODUCTION This chapter introduces the designer, installer, or user to the pro- cess whereby dry-chemical fire-suppression systems are de- signed. It outlines the process, introduces the limitations imposed on design by system hardware, as well as those mandated by performance considerations. It also gives a brief introduction to the basic types of Industrial dry-chemical fire-suppression appli- cations. As the designer familiarizes himself with this material, he should remember that analysis and design is a careful, step-by-step process. All steps must be followed, none can be omitted, and all unique aspects of a given application must be taken into ac- count if the resulting fire-suppression system is to deliver the desired protection. 3-1.1 Purpose and Design Dry-chemical systems are primarily used to extinguish flammable liquid fires. They are used in situations where fast extinguish- ment is required and where re-ignition sources are not present. Proper system design requires careful analysis to determine and define the nature of the hazard and the type of fire protection applicable to the hazard. The design sequence is described be- low. 3-1.2 Design Limitations In addition to performing the analysis and design process, and having a general knowledge of dry-chemical systems, the sys- tem designer must also have a working knowledge of all system and sub-system limitations; this knowledge is necessary to en- sure the effectiveness of the installed fire-suppression system. Each design must allow for the limitations of each part of the system: detector(s), actuator(s), nozzles, piping, tankage, and auxiliary control requirements. For example, some detectors are unsuitable for some types of fire hazard; the several nozzles available will distribute extinguish- ing agent in different patterns; some systems will require one kind of actuator rather than another, or may require a combina- tion of actuators; and finally, piping must be designed so that the agent is distributed effectively. The design limitations of industrial dry-chemical systems and their components are discussed in detail in this manual, and the designer should familiarize himself with them before beginning the design process. 3-2 APPLICATION TYPES There are relatively few generic types of dry-chemical fire suppression system applications. They vary from each other in terms of the nature, UL EX-2153 3-3 NFPA Class designation, and physical layout of the hazard, the flam- mable materials involved, whether or not the area to be protected is enclosed, whether there are associated ducts, plenums, and/or fosted ventilation systems, whether there is auxiliary equipment which must be controlled as pat of any fire-suppression action, and in other ways. The main application Wes are: 3-2.1 Total-Flooding Systems Total-flooding systems are used when there is an enclosure around the protected equipment or material. Total-flooding sys- tems are designed to fill the enclosure with a concentration of dry-chemical sufficient to extinguish a fire in the combustibles involved. Discharge of the dry-chemical is through fixed, ceiling mounted nozzles connected to one or more cylinders. See Sec- tions I and II of Chapter 4 for complete design limitations. 3-2.2 Spray-Booth Systems, Usually, a spray booth is an enclosure in which parts and equip- ment are spray painted or coated. When in operation, the booth is continually force-ventilated to remove flammable vapors gen- erated during operations. A typical spray booth is usually divided into two sections by a bank of filters that extends from floor to ceiling. The two sections of the paint spray booth are the work area and the plenum. The work area is the larger of the two sections, and is the place where the parts and equipment are sprayed. The plenum is the space into which the exhaust gases flow after passage through the filter bank. The most common types of paint spray booths are 1) vehicular (or automotive) spray booths and 2) industrial spray booths: 3-2.2.1 VEHICULAR SPRAY-BOOTH SYSTEMS The vehicle spray booths are used for painting automobiles, vans, trucks, and other mobile equipment. There are two types of ve- hicular spray booths, 1) solid back and 2) drive through. The solid-back spray booth uses a basic spray-booth arrange- ment with a filter bank separating the booth into a work area and plenum, with forced ventilation exhausting the flammable vapors through the plenum and associated duct work. The work area will have a large door through which the vehicle is brought into the booth. This door is to remain closed during spraying opera- tions. A drive-through spray booth will have doors at either end for vehicle entrance and exit from the booth. These doors are to remain closed during spraying operations. See Section III of Chapter 4 for complete design limitations. November 1998 Design Industrial Dry Chemical 3-2.2.2 OPEN-FACE/INDUSTRIAL SPRAY BOOTH SYSTEMS 3-4 THE ANALYSIS AND DESIGN PROCESS Most industrial spray booths have an open front face. The spray painting operation may be manually-controlled or fully-automated. A fully-automated booth uses a conveyor belt to move parts into and out of the spray booth and has uncloseable openings on both sides to allow for parts conveyance. See Sections IV and V of Chapter 4 for complete design limitations. 3-2.4 Local-Application Systems (For Indoor Use Only) Local application systems are used when there is no enclosure around the equipment or process being protected. In a local- application system, the dry chemical is discharged directly on an unendosed hazard through fixed nozzles connected to one or more cylinders. Local-application protection is designed to cover a fixed piece of equipment such as a dip tank or a process in an open area that is wind-protected or sheltered. The dry-chemical can be locally applied either overhead with nozzles located over the hazard area, or in a tankside manner with nozzles located along the sides of a flammable or combustible liquid tank. Care must be taken to include splash areas during hazard analysis of local-application systems. See Section VI of Chapter 4 for com- plete design limitations. 3-2.5 Hybrid Systems Some applications combine features of total-flooding and local application. For example, an oil-quenching system with an asso- ciated conveyor belt might require both forms of coverage in or- der to control combustion at the surface of the quenching bath (local application), and along the length of the conveyor system (total-flooding). In the case of spray booths Which vary widely in design, attention must be paid both to the requirements of the booth itself, as well as to associated ductwork or plenums. Some- times the requirements of the booth may differ from the needs of the associated duct/plenum(s), and the analysis-design process must take this into account. Note that each segment of the hybrid system uses separate sys- tem cylinders and distribution piping. 3-3 ANALYSIS AND DESIGN AS A PROCESS Analysis and design should be approached as a methodical pro- cess, and performed step by step. Only when all the steps are followed is the resulting system likely to perform as desired. If any step is omitted, it is probable that the system will not function as well as it should. The steps in the analysis and design pro- cess are: - Hazard analysis Suppression-system selection Nozzle selection, number and location - Tankage, number, size, and location Detector selection Actuator selection Piping layout Auxiliary requirements Analysis and design proceeds through the following steps: 3-4.1 Hazard Analysis Determining the NFPA Class and severity of the hazard. Analysis also includes determining the physical layout of the hazard, the manner and speed with which the fire might propagate, and the likelihood of its spreading into adjacent areas. The classification of flammable liquids can be found in NFPA 30: "Flammable and Combustible Liquid Code? Flammable liquid characteristics can be obtained from sources of reference such as safety data sheets and NFPA 325M: "Fire Hazard Properties of Flammable Liquids, Gases, and Volatile Solids." The severity of the fire hazard gen- erally relates to the possibility of explosive conditions by created by flammable materials within the confines of the protected area. This danger can usually be mitigated by safeguards such as ad- equate ventilation, explosion-proof wiring and fixtures, and prod- uct containerization. CAUTION IT IS IMPORTANT TO REMEMBER THAT, WITH DRY CHEMICALS, THERE IS NO INERTING OF THE PROTECTED SPACE FOLLOWING FIRE EX- TINGUISHMENT. IN APPLICATIONS WHERE IN- ERTING FOLLOWING FIRE EXTINGUISHMENT IS NECESSARY AND/OR DESIRABLE, CONSIDER- ATION SHOULD BE GIVEN TO GASEOUS EXTIN- GUISHING AGENTS SUCH AS FM-200, FE-13, OR CARBON DIOXIDE. 3-4.2 Suppression-System Selection Determining whether total-flooding, local application, or a combi- nation of the two approaches is best. Total-flooding systems are used if there is an enclosure around the hazard. Local-applica- tion techniques are used in situations where the hazard is unen- closed, but isolated from other hazards and can be protected by a dry-chemical discharge directed at it. 3-4.3 Nozzle Selection and Location Selecting the number and type(s) of nozzle(s) needed and locat- ing them so that the entire hazard is covered. Use the coverage/ distribution specifications for each nozzle type (ceiling mounted nozzles for total flooding applications, high or low overhead, or tankside nozzles, for local application, or duct/plenum nozzles for use in the exhaust ducts of spray booths) to determine the number of discharge nozzles required to deliver the necessary quantity of dry chemical given nozzle placement appropriate to the hazard. 3-4.4 Tankage Determination This step involves finding the quantity of dry-chemical agent re- quired, determining whether additional agent may be needed, and selecting the tankage which will supply the needed amounts. dry chemical. After determining the amount of dry chemical needed to control the hazard itself, determine whether any special con- ditions necessitate additional dry-chemical quantities. For ex- ample, it may be necessary to increase the dry-chemical discharge rate in order to offset the effects of ventilation, or it may be nec- essary to screen openings in an enclosure to prevent dry-chemi- UL EX-2153 34 November 1998 Industrial Dry Chemical Design cal leakage through those openings. Also, depending upon the criticality of the application and/or the potential for re-ignition, it may be necessary to provide a connected reserve supply of dry chemical. 3-4.5 Detector Selection Detector selection will depend on the response speed required, the probable heat level and rate of spread of the fire. The detec- tors used for industrial dry-chemical fire-suppression systems de- tect the heat energy released by the combustion of a fuel and oxygen. Upon detection of a fire, the detection system sends a signal to the system control head(s) which initiates the dry-chemi- cal discharge. The most commonly used detectors are the: Fixed-temperature fusible link Rate-compensated thermostat Pneumatic, rate-of-rise, heat-actuated detector (HAD) The following section details selection of the appropriate detec- tor and also discusses actuator systems. 3-4.6 Actuator Selection Depending on the hazard analysis, and the speed of response required, actuation may be manual, automatic (driven by the detector(s) used), or a combination of the two. See the section which follows for additional information. 3-4.7 Piping Layout Careful piping layout assures that that the agent reaches the distribution nozzles evenly and appropriately, and that piping limi- tations are addressed. These limitations involve pipe lengths, the number of elbows, and other factors such as the symmetry of piping between tankage and nozzles, and the allowable distances from agent storage tanks. These limitations are discussed in de- tail in the design examples contained in the sections on applica- tion types. 3-4.8 Auxiliary Requirements For example, adding controls to turn off forced-draft ventilation systems, fuel (or combustible-liquid) pumps, conveyers, etc. Such controls (usually automatic, and triggered by the system's detection apparatus) are often necessary to limit the severity or spread of a fire. 3-5 APPLYING THE METHOD Using the information gained in the previous steps, create the final design of the fire-extinguishing system: Decide the type(s) and number of discharge nozzles to be used and determine their locations. Determine the number, size, and location(s) of the dry-chemi- cal cylinders. Lay out the piping system(s). Design the automatic and/or manual fire-detection system(s): Select the type of automatic detector(s) to be used and de- termine detector location(s). Select the type of manual release(s) for the system and de- termine mounting location(s). Select the control system to interface between the fire-de- tection system and the fire extinguishing system. Determine the auxiliary equipment required such as pres- sure releases or alarm bells, fan or pump controllers. This process is illustrated in the sections of this manual dealing with applications, analysis, and design examples. UL EX-2153 3-5 November 1998 S Design Industrial Dry Chemical II. Detection Systems- 3-6 INTRODUCTION The detectors used for industnal dry-chemical fire-suppression systems are designed to detect the heat energy released by the combustion of a fuel and oxygen. Upon detection of a fire, the detection system sends a signal to the system control head(s) which initiates the dry-chemical discharge. Three commonly used detectors are the fixed-temperature fusible link, the rate-com- pensated thermostat, and the pneumatic, rate-of-rise, heat-ac- tuated detector (HAD). 3-7 FUSIBLE-LINK SYSTEMS Fusible link detectors are used for mechanical systems and are attached with a 1/16-inch steel cable to a mechanical control head. The fusible link is made of an alloy designed to melt at a certain temperature. When the fusible link melts, the tension in the cable connecting it to the control head is released, which actuates the spring-loaded plunger in the control head. This, in turn, actuates the cylinder valve, releasing the dry chemical into the distribution system. TEMPERATURES RECORDED. SEE TABLE 2-3 FOR LINK MAXIMUM EXPOSURE TEMPERATURES. 3-7.2 Fusible Link Spacing The fusible-link housing kit, shown in Figure 3-1, provides the flexibility required to install fusible links in a wide variety of in- dustrial applications. Depending upon the size of the area being protected, the number of fusible links used can range from a minimum of I up to a maximum of 25. When multiple fusible links are used, they are connected to each other in series using 1/16-inch stainless steel cable to form a continuous chain. The 1/16-inch cable leads to the mechanical control head from the link nearest to the control head. Kidde Rapid-Response Thermo-Bulb links (KGR) can be spaced every 20 feet for smooth ceilings up to 12 feet high. Consult NFPA 72E for reductions in spacing for ceiling heights in excess of 12 feet, and for spacing guidelines when different ceiling ar- rangements are encountered. Potential fire hazards and/or fire development scenarios may re- quire closer fusible link spacings. Consult the authority having jurisdiction in these situations. EMT EMI ADAPTER In addition to releasing the dry chemical to suppress the fire, the ADAPTER71 WEMT r mechanical control head can be supplied with one or two op- - tional microswitches for equipment-interlock purposes. The me- CONTROL HEAD . chanical control head is equipped with a local manual release FROM OTHER I-A" lever and can also incorporate a remote manual release station. DETECTORS j/ /SIBL 4MPSLEEVE HOOK FUELINK 3-7.1 Fusible Link Selection For automatic actuation to occur during a fire, the fusible links must be heated sufficiently to melt and cause actuation. Experi- ence has shown that it maytake several minutes for fusible links to actuate, and actuation is dependent upon: Fire intensity Fusible link temperature rating Fusible-link spacing and location In order to minimize delays in link response time, it is necessary to conduct a temperature survey at all locations where detector links will be installed. The survey must be conducted under maxi- mum operating conditions (i.e., at the highest operating tempera- tures and airflows) to determine the optimum exhaust airflow locations and record the peak temperatures that are expected to occur. Once the survey is completed: Select the lowest temperature-rated link that can be used. Make sure that the maximum exposure temperature of the link exceeds the maximum temperature obtained from the survey. Make sure that the links are located in the exhaust airflow, not in dead air spaces. This will provide the fastest response. Th.iMll[cI TO AVOID ACCIDENTAL SYSTEM DISCHARGE, LINKS .

Figure 3-3 shows single and dual-mechanical, remote pull stations. Use a tee pulley for dual pull stations. Table 3-1 gives the maximum cable length and number of corner pul- leys permitted for this sort of installation. Note that the cable line to the remote pull station(s) is run in EMT for protection. Remote manual pull stations shall be located in a path of exit or egress and shall be clearly identified. Thermostats are used with electric control heads and are elec- trically wired directly to the control head or to an intervening control unit. CAUTION ALL SYSTEMS WITH ELECTRICACTUATION MUST BE PROVIDED WITH A CONTINUOUS, SUPERVISED BACKUP POWER SOURCE CAPABLE OF OPERAT- ING THE SYSTEM FOR AT LEAST 24 HOURS, UN- LESS THIS REQUIREMENT IS EXPLICITLY WAIVED BY THE AUTHORITY HAVING JURISDICTION. The actuating cam in an electric control head is held in place by a solenoid. The thermostat's contacts are normally in the open position. When a fire raises the temperature at the thermostat, the thermostat's contacts close, sending a signal directly to the control-head solenoid or to an intervening control unit (which sends a signal to the control-head solenoid). This releases the actuating cam, which causes the plunger to drop and actuates the cylinder valve. The dry chemical is then discharged through the distribution system. In addition to releasing the dry chemical to suppress the fire, the electric control head is equipped with microswitches for equip- ment-interlock purposes. Electric control heads are equipped with a local manual release lever, and can incorporate a remote manual release. UL EX-2153 3-7 November 1998 Design Industrial Dry Chemical CAU11ON 3-8.1 Thermostat Selection The thermostat must be heated to its setpoint temperature for automatic actuation to occur during a fire. Automatic actuation is dependent upon: Fire intensity Thermostat setpoint C. Thermostat spacing and location 3-9 PNEUMATIC SYSTEMS Pneumatic, heat-actuated detectors (HADs) are used for pneu- matic systems and are connected via 1/8-inch outside-diameter (00) copper tubing either directly to a pneumatic control head or to an intervening mercury check. The heat-actuated detector consists of a hollow brass chamber having no moving parts and with appropriate connectors for at- tachment to 1/8-inch CD copper tubing. Upon a rapid rate of tem- perature rise due to a fire in the protected area, the pressure in 'the HAD increases, and this pressure increase is transmitted via the copper tubing directly to the pneumatic control head or to an inter- vening mercury check (which sends a signal to the pneumatic con- trol head). This releases the actuating cam, which causes the plunger to drop and actuates the cylinder valve. The dry chemical is then discharged through the distribution system. The HAD's, tubing, and pneumatic control head are vented to prevent normal temperature increases from actuating the system. In addition to releasing the dry chemical to suppress the fire, the pneu- matic control head can be supplied with one or two optional microswitches for equipment-interlock purposes. The pneumatic con- trol head is equipped with a local manual release lever and can also incorporate a remote, mechanical, manual release station. 3-9.1 HAD Selection IT IS LIKELY THAT INDUSTRIAL APPLICATIONS IN- VOLVING FLAMMABLE OR COMBUSTIBLE LIQUIDS WILL BE ENCLOSED WITHIN OR SURROUNDED BY AREAS THAT WILL BE CLASSIFIED AS CLASS I OR CLASS II, DIVISION I OR DIVISION 2 LOCATIONS. DRY-CHEMICAL SYSTEM ELECTRICAL COMPO- NENTS, SUCH AS THERMOSTATS, LOCATED WITHIN THESE AREAS SHALL BE RATED FOR USE IN CLASSIFIED AREAS, AND ALL WIRING TO THESE COMPONENTS SHALL CONFORM TO THE PROVI- SIONS OF NFPA 70, NATIONAL ELECTRICAL CODE, FOR CLASS I OR CLASS II, DIVISION I, OR DIVI- SION 2 LOCATIONS. ANY INDUSTRIAL SYSTEM CONTROL HEAD WITH A MICROSWITCH IS NOT SUITABLE FOR USE IN A CLASSIFIED AREA. In order to minimize delays in thermostat response, it is impera- tive that a temperature survey be conducted at all locations where thermostats will be installed. The survey must be conducted un- der maximum operating conditions (i.e., at the highest operating temperatures and airflows) to determine the optimum exhaust S airflow locations and record the peak temperatures that are ex- pected to occur. Once the survey is completed: Select the thermostat with the lowest usable setpoint. Make sure that there is approximately a 75 degree F to 100 degree F buffer between the thermostat setpoint and the maximum temperature obtained from the survey. Make sure that the thermostats are located in the exhaust airflow, not in dead-air spaces. This will provide the fastest detector response. 3-8.2 Thermostat Spacing The number of thermostats required for a particular industrial application is a function of the size of the area being protected. Since the thermostat is an unpowered electrical component, there is no upper limit established for the maximum number of detec- tors that can be used for a given system. In practice, issues such as voltage drops caused by wiring resistance impose certain limitations on the lengths of wiring that can be used. For applica- tions that require control units, consult the appropriate control- unit installation manual for wiring limitations. When multiple thermostats are used, they are electrically connected in parallel. Thermostats are spaced every 20 feet for smooth ceilings up to 12-feet high. Consult NFPA 72E for reductions in spacing for ceiling heights in excess of 12 feet, and for spacing guidelines when different ceiling arrangements are encountered. 3-8.3 Cabling Limitations S Electrical systems using thermostats may use remote mechani- cal release stations and tandem control heads, Consult Table 3- 1 for installation limits of mechanical cable lines. The HAD must be rapidly heated for automatic actuation to oc- cur during a fire. Automatic actuation is dependent upon: Fire intensity HAD spacing and location In order to minimize delays in HAD response, and to account for transient temperature fluctuations in the protected area, it is im- perative that a temperature survey be conducted at all locations where HADs will be installed. The survey must be conducted under maximum operating conditions (i.e., at the highest operat- ing temperatures and airflows) to determine the optimum exhaust airflow locations and record the peak temperatures that are ex- pected to occur. Once the survey is completed: Ensure that no HAD is mounted at a location where normal process conditions can cause temperature increases to oc- cur at rates faster than 20 degrees F per minute. Make sure that the HADs are located in the exhaust airflow, not in dead-air spaces. This will provide the fastest detector response. 3-9.2 HAD Spacing The pneumatic, heat-actuated detector (HAD), shown in Figure 3-4, is attached to a mounting bracket for ease of installation in industrial applications. Depending upon the size of the area be- ing protected, the number of HADs used can range from a mini- mum of 1 up to a maximum of 12. When up to 4 HADs are required, they are parallel branched by means of tee connec- tions from a common tubing line, and the tubing is connected directly to the control head. When more than 4 HADs are re- quired, they are evenly distributed on separate tubing lines and the individual tubing lines are connected to a mercury check, P/N 871346. The mercury check is then connected to the pneumatic control head.

Consult NFPA 72E for reduction in spacing for ceiling heights in excess of 12 feet, and for spacing guidelines when different ceiling arrangements are encountered. NOTE: HADs are spaced every 15'-10" for applications requiring Factory Mutual System Approval. 3-9.3 Tubing Limitations The response time of a pneumatic detection system is depen- dent upon a number of factors, such as: Fire intensity HAD spacing and location Control-head setting and vent size Volume of copper tubing It is important to remember that the system will actuate when the entire sensing volume (HADs, copper tubing, and pneumatic- control-head sensing chamber) is pressurized to a level equal to the control-head setting (For example, 4 inches of water). To ensure a fast response to rapidly progressing or intense fires, the tubing system must be limited to a total length of 200 feet or less of 1/8-inch OD copper tubing for a single-line system, or a total length of 200 feet or less of 1/8-inch OD copper tubing for each line of a multi-branch system. NOTE: The final leg of the copper tubing system connects to the pneumatic control head by means of 3/16-inch 00 tubing. There is no way to enclose this leg in electrical metal tubing (EMT) for protection; therefore, thicker walled tubing is required.

Refer to Table 3-1 for installa- tion limits of mechanical cable lines. 3-10 OTHER DETECTION SYSTEMS Although it is most common to use heat detectors for industrial fire protection systems, there may be some applications where an- other mode of detection, such as flame or radiation detection, is more appropriate. Any UL-listed and/or Factory-Mutual-System- approved detector may be used to actuate the extinguishing sys- tem provided that the detector is appropriate to the type of combustibles involved and is connected to a listed and compatible control unit. The control unit shall be UL-listed and/or Factory Mu- tual System approved for releasing device service and compatible with the dry chemical extinguishing system equipment. There are two types of industrial fire-suppression systems; local application and total flooding.

Total-Flooding Systems 4-1 TOTAL-FLOODING SYSTEMS Total-flooding systems are used when there is an enclosure around the protected equipment or material. Total-flooding sys- tems are designed to fill the enclosure with a concentration of dry-chemical sufficient to extinguish a fire in the combustibles involved. Discharge of the dry-chemical is through fixed, mounted nozzles connected to one or more cylinders. Regular, BC (sodium-bicarbonate base) dry-chemical is used to protect flammable or combustible liquid total-flooding hazards. Multi-purpose, ABC (monoammonium-phosphate base) dry chemical is used for total-flooding applications involving ordinary combustibles (Class A) and flammable or combustible liquids. NOTE: For a total-flooding system to be effective, it is important that all ventilation be shut off no later than the start of dry-chemical discharge, and where possible, that all openings be closed. When ventilation is NOT shut down, supplementary dry chemical must be added at the point of air entry. Refer to NFPA 17, Section 4- 2.2.6.1 and the example calculation below. EXAMPLE: Additional Hazard Volume to be Protected 6 ft. x 10 ft. air-input opening 100 ft/mm. velocity (V) measured at opening .10 lb./10 sec. or I lb/sec discharge rate 1350 cu. ft. maximum coverage per nozzle Calculate the following: Area (A) = (6 ft.)(10 ft.) = 60 sq. ft. Air Flow (Q) = VA = (100 ft./min.)(1 min./60 sec.)(60 sq. ft.) = 100 cu. ft./sec. Volume of air removal during 10 second discharge: = (100 cu. ft/.sec.)(10 sec.) = 1000 cu. ft. Additional nozzle coverage: = (1000 cu. ft.)/(1350 cu. ft.) = 0.74 nozzle(s) Rounding up 0.74 to next whole number = one additional nozzle at point of air entry. 4-2 UNCLOSEABLE OPENINGS The concept of an uncloseablé opening applies only to total flooding systems. An uncloseable opening is a permanent open- ing in the enclosure envelope that cannot be closed or shut prior to or at the start of dry-chemical discharge. Hazards with an uncloseable opening area equal to 5% or less of the total enclosure surface area do not require any additional dry chemical. The Kidde dry-chemical extinguishing system units have not been evaluated by Underwriters laboratories Inc. with respect to the total flood protection of hazards incorporating unclosable openings exceeding 5% of the total hazard surface area.

Each cylinder is protecting an area or volume that does not exceed the listed coverage for a single cylinder. Each cylinder has its own distribution piping and all piping conforms to established limitations for pipe sizes and pipe lengths. All cylinders are actuated simultaneously. NOTE: For total-flooding systems, different size cylinders (e.g., lND-25 and IND-50) can be combined to protect the same hazard. 4-3 USE OF TOTAL FLOODING SYSTEMS Total flooding systems are used when there is an enclosure around the protected equipment or material. All ventilation must be shut-down at the time of agent discharge and, if possible, all openings must be closed. 4-3.1 Coverage One lND-21 or lND-25 must use two total-flooding discharge nozzles (PIN 83-100005-001. See Chapter 2 for description), pro- viding a total area and volume coverage of 225 square feet and 2,700 cubic feet, respectively. One lND-45 or IND-50 must use four total flooding discharge nozzles, providing a total area and volume coverage of 450 square feet and 5,400 cubic feet, re- spectively. The maximum area and volume coverages are in Table 4-1. Each nozzle should be centered in its protected volume segment. For ceiling heights up to 20 feet, the volume coverage per nozzle is retained, but the area coverage is reduced as listed in Table 4- 1 Figures 4-1, 4-2, and 4-3 show maximum area coverages for total flooding applications. 4-3.2 Uncloseable Openings Hazards with an uncloseable-opening area equal to 5% or less of the total enclosure surface area do not require any additional dry chemical. The Kidde dry chemical extinguishing system units have not been evaluated by Underwriters Laboratories Inc. with respect to the total flood protection of hazards incorporating unclosabte openings exceeding 5% of the total hazard surface area. 4-3.3 Equivalent Length When a fluid flowing in a pipeline changes direction, such as at an elbow or at a tee, the ensuing disruption of the flow always results in a loss of fluid pressure. For the purposes of pressure drop calculations, it is convenient to replace a fitting with a sec- tion of straight pipeline. The length of the substituted piece of pipe is chosen so that the pressure drop across it equals the pressure loss through the fitting it replaced. In this sense, each type of fitting is equivalent to a certain length of straight pipeline, and each filling is assigned an "equivalent length." Substitutions of this type allow each point in the distribution system to be de scribed by two numbers - one number being the actual linear length of pipe to that point, and the second number being the total equivalent length of pipe to that point, taking fittings into account. Fittings, for equivalent-length purposes, are defined as side- flow (bull) tees and 90-degree elbows. Straight connectors and unions may be used anywhere in the distribution system, since there is no change in direction at these fillings to contribute to the equivalent length. Refer to Table 4-2 for equivalent-length data. The main supply line, the sub-supply lines (four-nozzle cylin- ders), and the nozzle branch lines are each rated for a maxi- mum pipe length and a maximum equivalent pipe length. There is no minimum pipe length or fitting requirement. Any number of 90-degree elbows can be used on the supply line, subject to the equivalent length limitations. Additional 90-degree elbows can be used on the sub-supply lines and the nozzle branch lines, subject to equivalent length and balancing constraints. The change in direction at the cylinder's valve outlet is not counted as a 90-degree elbow. Table 4-2.

In these cases, tm or more cylinders are applied to a single hazard installation. .The protected space is divided into volume segments for cover- age purposes. For applications with ceiling heights up to and including 12 feet, the maximum surface area coverage for each nozzle is 112.5 square feet, subject to a longest side, for rectan- gular areas, not to exceed 15 feet. The maximum distance from the ceiling to the nozzle tip is 4.5 inches. DRY CHEMICAL CYLINDER 30.0 FT Figure 4-1.

In order to ensure the proper flow division of dry chemical at each tee, certain minimum pipe lengths must be observed when approaching a tee following a change in flow direction. These minimum pipe lengths are shown in Figure 44. NOTE: These minimum pipe lengths also apply to local- application systems.

Total-Flooding System Design Example 44 SOLVENT STORAGE ROOM EXAMPLE A solvent storage room 14 feet long by 10 feet wide by 10 feet high is known to contain the following materials and maximum storage quantities. Flash Point Maximum Material (Degrees F) Quantity (Gallons) Acetone 60 Methyl Ethyl 16 60 Ketone Toluene 40 60 The room has no uncloseable openings, and all the flammable liquids are stored in one-gallon metal containers. No dispensing of liquids is allowed in the room. The owner wants to protect this area with a dry-chemical system. 4-4.1 Hazard Analysis The objective of the fire suppression system is to detect and extinguish a flammable-liquid fire involving any of the materials stored in the room. Since the flammable liquids are stored in a room with no undoseable openings, a total-flooding dry chemi- cal system will be designed for this application. The design analysis should start with a dear statement of the haz- 10.-0. ards involved in the application. In general, the flammability classifi- cation for a liquid is determined by its flash point. NFPA 30, Flam- mable and Combustible Uquids Code, defines a combustible liquid as a liquid having a flash point at or above 100 degrees F (37.8 degrees C), and defines a flammable liquid as a material having a flash point below 100 degrees F. Based on the data above, all of the materials stored in the room are flammable liquids. Following the hazard identification (i.e., flammable liquids), the next step would be to determine the applicability of dry chemical to fires in the flammable materials being stored. This can only be ascertained from material safety data sheets supplied by the manu- facturers of the flammables. These safety data sheets must be care- fully reviewed by the designer priorto starting the system design. In our application, a review of the appropriate safety data sheets reveals that regular dry chemical (BC povldef) will extinguish fires in all of the mate- rials being stored in the mom. The severity of the hazard can be assessed in the following man- ner. While it is obvious that the fuel loading is quite heavy in the storage room, the owner has taken all of the necessary steps to comply with the flammable liquid code (NFPA 30). The room is ventilated, and all wiring and equipment located in the room is suit- able for Class 1, Division 2 locations. The flammables are stored in small containers, and no dispensing is allowed in the room: Under these conditions, the most likely fire scenario would involve a fuel spill of up to one gallon (i.e., one container). Given these param- eters, it is unlikely that a flammable vapor and air mixture will de- velop in the room. Therefore, a dry chemical extinguishing system is appropriate for this application. LEGEND [4 Figure 4-8. Solvent-Storage Room UL EX-2153 4-7 November 1998 Applications and Examples Industrial Dry Chemical 4-4.2 Nozzles .The number of nozzles required for the extinguishing system is deter- mined by dividing the solvent storage room into volume segments. We will use the total-flooding nozzle, P/N 83-1000054)01. A nozzle will be ceiling mounted and centered in each of the protected volume seg- ments. The number of nozzles required is as follows. Since the ceiling height (10 feet) is less than 12 feet, each total flooding nozzle can cover a maximum surface area of 112.5 square feet (10.6 ft. by 10.6 ft.), with a longest side of 15 feet. The num- ber of nozzles is determined by successively dividing the length and width dimensions by the nozzle linear spacing (15 feet), rounding up the calculated quantities to the nearest whole num- bers, and then multiplying the calculated quantities. - NOTE: The nozzle linear spacing for square areas is 15 feet. For rectangular areas, the nozzle has two linear spacings (e.g., 7.5 feet and 15 feet). For estimation purposes in our example, it is more practical to use the square area linear spacing of 10.6 ft., even though the storage room has a rectangular cross-sectional area. Divide the length of the storage room by the nozzle's linear spac- ing and round up. Length= 14 ft. At 10.6 ft./nozzle = 1.0 or (rounding up) two nozzles (length- wise). Divide the width of the storage room by the nozzle's linear spac- ing and round up. Width = loft. .At 10.6 ft./nozzle = 1.06 or (rounding up) two nozzles (widthwise). Multiply the lengthwise and widthwise nozzle quantities to de- termine the number of nozzles required. No. of nozzles = I x 2 =2 There are no special conditions such as excessive ventilation rates or uncloseable openings that necessitate additional quan- tities of dry chemical for fire-extinguishing purposes. Also, fire incident data suggests that the probability of fire in this applica- tion is low (although, should a fire occur and not be suppressed, the consequences would be catastrophic). Therefore, we will not use a reserve dry chemical extinguishing system. 4-4.3 Cylinders Each lND-25 cylinder can supply two total-flooding nozzles, and each IND-50 cylinder can supply four nozzles. Thus, one 25-lb. cylinder or one 50-lb. cylinder can be used to protect the solvent- storage room. We will use one 25-lb. cylinder because it is more cost-efficient to do so. In general, the number of cylinders for a total flooding application is determined by dividing the number of required nozzles by 4 (for nozzle quantities greater than 2). This determines the number of 50-lb. cylinders (or 45-lb. cylinders, where applicable). Any leftover or remainder nozzles in quantities of 2 can be supplied by a 25-lb. (or 21-lb., where applicable) cylinder. Thus, for our application, the number of 25-lb. cylinders can be calculated as follows: For Nozzles At 2 Nozzles/25-lb. cylinder = One 50-lb. cylinder 44.4 Detection System The flammable liquids contained in the solvent storage room are highly volatile and, in the event of a spill and subsequent ignition, the resulting fire would progress very rapidly and would release a large quantity of heat Thermostats, HADs, or Kidde KGR Rapid Response Fusible Links should be used for early detection in order to reduce the size and duration of the fire, and also to minimize the subsequent vaporization of fuel as a result of the fire. WARNING ELECTRICAL WIRING AND EQUIPMENT LOCATED IN- SIDE ROOMS USED FOR FLAMMABLE-LIQUID STOR- AGE SHALL BE SUITABLE FOR CLASS-I, DIVISION-2 LOCATIONS. THERMOSTATS SHALL BE RATED FOR USE IN CLASSIFIED AREAS, AND ALL WIRING TO THESE COMPONENTS SHALL CONFORM TO THE PRO- VISIONS OF NFPA70, NATIONAL ELECTRICAL CODE, FOR CLASS-I, DIVISION-2 LOCATIONS. ANY SYSTEM CONTROL HEAD WITH A MICROSWITCH IS NOT SUIT- ABLE FOR USE INA CLASSIFIED AREA. The number of detectors is determined by successively divid- ing the enclosure's length and width by the detector's linear spacing (20 feet; 15'-10" for an FM application with HADs), round- ing up the calculated quantities to the nearest whole numbers, and then multiplying the calculated quantities. Assuming that there is no FM approval required, divide the length of the storage room by the detector's linear spacing and round up. Length = 15 ft. At 20 ftidetector = 0.8 or (rounding up) I detector (lengthwise). Divide the width of the storage room by the detector's linear spac- ing and round up. Width= loft. At 20 ft./detector = 0.5 or (rounding up) 1 detector (widthwise). Multiply the lengthwise and widthwise detector quantities to de- termine the number of detectors required. No. of detectors = 1 x I = I The type of control head (either electnc or pneumatic) for the cylinder will be dictated by the choice of either an electric (ther- mostatic) or a pneumatic (HAD) detector. CAUTION ALL SYSTEMS WITH ELECTRIC ACTUATION MUST BE PROVIDED WITH A CONTINUOUS, SUPERVISED BACKUP POWER SOURCE CAPABLE OF OPERAT- ING THE SYSTEM FOR AT LEAST 24 HOURS, UN- LESS THIS REQUIREMENT IS EXPLICITLY WAIVED BY THE AUTHORITY HAVING JURISDICTION. The layout of the dry-chemical system is shown in Figure 4-8. The piping to the nozzles must fall within the parameters shown in Figure 4-7. To complete the system design, the designer must determine what is required to stop the ventilation upon dry-chemi- cal discharge, and would also need to review any other job re- quirements, such as alarm notification.
