REGULATED RELEASE ASSEMBLY (MECHANICAL)
The ANSUL AUTOMAN Regulated Mechanical Release Assembly
(Part No. 429853) contains the regulated release mechanism,
expellant gas hose for agent tank hookup, and enclosure knock-
outs to facilitate installing actuation piping; expellant piping; detec-
tion system; and additional equipment. This regulated release
assembly is used in single, double, and multiple-tank systems and
must be mounted to a rigid surface. The release mechanism can
be used to interconnect both the actuation and expellant gas lines
as required per system design. The regulator is designed to allow
a constant flow of gas into the tank at 110 psi (7.6 bar) when the
system is actuated. The agent tank must be ordered separately.
In single, double, and multiple-tank systems, the provided expel-
lant gas hose connects the agent tank to the bottom outlet of the
regulator. In double and multiple-tank system configurations, the
back outlet of the regulator is used as an expellant gas feed for
one additional tank-enclosure or tank-bracket hookup. The enclo-
sure contains the required knockouts to facilitate this connection.
If a pressure switch is to be attached to the regulator, additional fit-
tings are required.
The tank is mounted within the enclosure. The tank contains an
adaptor/tube assembly with a burst disc union. The burst disc
helps prevent siphoning of the agent up the pipe due to significant
temperature fluctuations in the area where the tank is located. The
tank is stainless steel and, under normal conditions, requires
hydrostatic testing every twelve years.
The detection and additional equipment required per system
design are connected to the release mechanism. The enclosure
contains knockouts to facilitate detection and additional hookups.
The system can be actuated automatically or manually. Automatic
actuation occurs when a fusible link within the detection system
separates in a fire condition. Manual actuation of the system
occurs when personnel pull on the remote manual pull station
pull ring.

REGULATED RELEASE ASSEMBLY (ELECTRICAL)
The ANSUL AUTOMAN Regulated Electrical Release Assembly
(Part No. 429856) is identical to the mechanical version except it
also contains a factory installed 120 VAC solenoid and electrical
switch.
The solenoid is used to provide electrical actuation of the release
mechanism. The electric switch is used to protect the solenoid by
opening the circuit to the solenoid once the system is fired.
Additional electrical switches can be added as required for auto-
matic equipment and gas shut-off accessories, as well as initiating
audible and visual alarms.

enclosure or bracket assembly. The regulator is designed to allow
a constant flow of nitrogen into each agent tank connected (two
o. tanks maximum) at 110 psi (7.6 bar).
The pneumatic actuator is designed to puncture the expellant gas
cartridge seal upon receiving pressure from the regulated release
assembly actuation piping. The enclosure contains a knockout to
facilitate distribution piping hookup.

24 VDC REGULATED RELEASE ASSEMBLY (ULC APPROVED
ONLY)
The 24 VDC Regulated Release Assembly, Part No. 429859, is
used where electric, thermostat detection is required via the use of
a releasing control unit. This assembly consists of a 24 VDC
ANSUL AUTOMAN Il-C regulated release mechanism, expellant
gas hose, and enclosure knockouts to facilitate installing actuation
piping, expellant piping, detection system, and additional equip-
ment. Agent tank must be ordered separately.
The system can be actuated automatically or manually. Automatic
actuation occurs when the control panel receives a signal from the
detection circuit. The panel then sends an electrical signal to the
24 VDC regulated release, causing it to actuate. When actuation
occurs, the gas cartridge is punctured, pressurizing the agent tank
and discharging the agent through the distribution piping. Manual
actuation of the system occurs when personnel pull on the remote
manual pull station pull ring.

tion line through restaurant hoods and duct. The adaptor accepts
a high temperature pulley elbow and, when used, correctly posi-
tions the elbow or conduit in line with the conduit adaptor hole in

DETECTORS
The detector consists of three basic components: the bracket, link-
age, and fusible link. (Fusible links are not included and must be
ordered separately.) The bracket holds the entire assembly to the
mounting surface. The linkage is used to support the fusible link.
The fusible link is designed to separate at a specific temperature
and release the wire rope, thereby actuating the regulated release
mechanism.
The scissor style detector allows the wire rope to be strung com-
pletely through the detection system conduit and brackets first and
the detector linkage assemblies are then clipped on later.
The detector consists of two types of assemblies:
The Terminal Detector (Part No. 435546) includes a test link and
is placed last in a series of detectors. This detector is sometimes
referred to as the end-of-line detector and is thus named because
it is at the point at which the wire rope "terminates," or is anchored
at the detector bracket. Only one terminal detector is required per
detection system.
The Series Detector (Part No. 435547) is any detector located in-
line between the regulated release assembly and the terminal
detector.
When using Part No. 435546 and 435547 detectors, a total of 15
detectors can be in one detection system: 14 series detectors, Part
No. 435547 and 1 terminal detector, Part No. 435546.
'Note: Series Detector, Part No. 435547, is also available as Part
No. 435548, 25/Pkg.
SCISSOR STYLE - PART NO. 435546 AND 435547
PULLEY TEE
The Pulley Tee (Part No. 427929) is used to change the direction
of two wire ropes by 90°. It must be used in areas where the tem-
peratures are within the range of 32 IF to 130 OF (0 °C to 54 °C).
Pulley tees can be used in mechanical gas valve actuation lines
and remote manual pull station lines. Pulley tees cannot be used
within a detection line.
FIGURE 26
000447
STAINLESS STEEL CABLE
The 1/16 in. stainless steel cable is run from the terminal detector,
through conduit, all series detectors and pulley elbows, and into
the regulated release mechanism trip lever. When any fusible link
separates, the tension on the cable is relaxed, and the trip lever
actuates the regulated release mechanism. The cable can also be
used for mechanical gas valves and remote manual pull stations.
The cable is available in 50 ft (15 m) (Part No. 15821) and 500 ft
(152.4 m) (Part No. 79653) lengths.

PULLEY ELBOWS
There are two types of pulley elbows used to change the direction
of the wire rope by 90°. ANSUL recommends for temperatures not
in excess of 700 IF (371 °C). Part No. 415670 has socket ends
with set screws for 1/2 in. conduit, and Part No. 423250 has com-
pression ring ends also for 1/2 in. conduit. Pulley elbows must be
ordered in quantities of 50 as Shipping Assembly Part No. 415671

REMOTE MANUAL PULL STATION
The remote manual pull station (Part No. 434618 or 435960) is
made out of a molded red composite material. The red color
makes the pull station more readily identifiable as the manual
means for fire suppression system operation. The pull station is
compatible with the ANSUL Flexible Conduit. The molded manual
pull station should be mounted at a point of egress and positioned
at a height determined by the authority having jurisdiction. Trim
Rings, Part No. 427074 (pack of 10), are available.

dard EMT conduit or can be used with EMT conduit. Flexible con-
duit can be used only with the Molded Manual Pull Station, Part
No. 434618, and mechanical gas valve installations. The Flexible
Conduit comes in a 500 ft (152.4 m) length, Part No. 434525, or

MANUAL RESET RELAY
The Manual Reset Relay, Part No. 426151, is required when using
an electrical gas valve shut-off system. After the electric gas valve
has closed, either due to system actuation or power failure, the
valve cannot be re-opened, allowing gas to flow, until the reset
relay button is manually pressed, re-energizing the circuit. The
reset relay is available 120 VAC. The manual reset relay is also
recommended for electrical shut down.

In addition to eliminating the siphoning effect, the common in-line
burst disc assembly eliminates the possibility of one or more indi-
vidual discs located in the tank adaptor from failing to burst. The
assembly consists of a stainless steel body which houses the
burst disc. When utilizing this assembly in a manifolded system, it
is necessary to modify (remove) the burst disc located in all of the

SYSTEM DESIGN
The ANSUL R-102 Restaurant Fire Suppression System may be
used on a number of different types of restaurant cooking appli-
ances and hood and duct configurations. The design information
listed in this section deals with the limitations and parameters of
this pre-engineered system. Those individuals responsible for the
design of the R-102 system must be trained and hold a current
ANSUL certificate in an R-102 training program.
The R-102 and the PIRANHA systems use compatible agents and
components, therefore, they may be used together for cooking
appliance, hood, and duct protection. The primary ANSUL
AUTOMAN Release can be either an R-102 or a PIRANHA
ANSUL AUTOMAN Release and can actuate up to two additional
R-102 or PIRANHA Regulated Actuators. In systems utilizing a
101 remote release, any combination of the maximum number of
regulated actuators can be used.
Both systems must actuate simultaneously.
Each system must be designed and installed per its appropri-
ate manual.
Adjacent appliances requiring protection must be protected
with the same type of system, either R-102 or PIRANHA,
unless the center-to-center spacing between the adjacent
R-1 02 and PIRANHA nozzles is no less than 36 in. (91.4 cm).
When appliances are protected with R-102 nozzles, the hood
and connecting duct above those appliances cannot be pro-
tected with PIRANHA nozzles.
Mixing systems in a common plenum is not allowed.
One of the key elements for restaurant fire protection is a correct
system design. This section is divided into ten sub-sections: Noz-
zle Placement Requirements, Tank Quantity Requirements, Actu-
ation and Expellant Gas Line Requirements, Distribution Piping
Requirements, Detection System Requirements, Manual Pull Sta-
tion Requirements, Mechanical Gas Valve Requirements, Electri-
cal Gas Valve Requirements, Electrical Switch Requirements, and
Pressure Switch Requirements. Each of these sections must be
completed before attempting any installation. System design
sketches should be made of all aspects of design for reference
during installation.
NOZZLE PLACEMENT REQUIREMENTS
This section gives guidelines for nozzle type, positioning, and
quantity for duct, plenum, and individual appliance protection. This
section must be completed before determining tank quantity and
piping requirements.
Duct Protection - Single Nozzle
All duct protection is UL listed without limitation of maximum duct
length (unlimited length). This includes all varieties of ductworks
both horizontal and vertical including ducts that run at angles to
the horizontal and ducts with directional bends.
The R-102 system uses different duct nozzles depending on the
size of duct being protected.
GENERAL INFORMATION
1. Nozzles must be located 2-8 in. (5-20 cm) into the center of the
duct opening, discharging up. See Figure 1.

(20 cm) maximum, to a point just beyond the damper assem-
bly that will not interfere with the damper. Exceeding the maxi-
mum of 8 in. (20 cm) in this way will not void the UL listing of
the system.

TWO (2) 1 NOZZLES - PART NO. 419335 - "V' BANK PRO-
TECTION
Two 1 nozzles will protect 10 linear feet (3.1 m) by 4 ft(1.2 m)
wide of "V' bank plenum. The nozzles must be mounted in the
plenum, 2 to 4 in. (5 to 10 cm) from the face of the filter, centered
between the filter height dimension, and aimed down the length.
The nozzle must be positioned 0-6 in. (0-15 cm) from the end of the
hood to the tip of the nozzle. See Figure 11.

HORIZONTAL PROTECTION - OPTION 2
1W NOZZLE - PART NO. 419336— "V" BANK PROTECTION
One 1W nozzle will protect 6 linear feet (1.8 m) of 'V' bank plenum.
The nozzle must be mounted horizontally, positioned 1/3 the filter
height down from the top of the filter. Nozzles can be located at 6 It
(1.8 m) spacings on longer plenums. The nozzle must be positioned
0-6 in. (0-15 cm) from the end of the hood to the tip of the nozzle.
See Figure 10.
For a plenum, either single or "V' bank, with a linear extension
longer than 10 ft (3.1 m), each bank may be protected using one
iN nozzle every 10 ft (3.1 m) or less depending on the overall
length of the plenum. See Figure 12. The nozzles may point in the
opposite directions as long as the entire plenum area is protected,
and the 10 ft (3.1 m) limitation is not exceeded. See Figure 13. The
nozzle positioning shown in Figure 14 is not an acceptable method
of protection because the plenum area directly under the tee is not
within the discharge pattern of either nozzle.
