1. DESCRIPTION
Viking Freedom® Residential Concealed Pendent Sprinkler VK494 is a small
thermosensitive, glass-bulb residential sprinkler designed for installation on concealed
pipe systems where the appearance of a smooth ceiling is desired. The orifice design,
with a K-Factor of 4.9 (70.6 metric*), allows the sprinkler's efficient use of available
water supplies for the hydraulically designed fire-protection system. The fast
response glass bulb operating element and special deflector characteristics meet
the challenges of residential sprinkler standards.
The sprinkler is pre-assembled with a threaded adapter for installation with a
low-profile small-diameter cover assembly installed flush to the ceiling. The two-
piece design allows installation and testing of the sprinkler prior to installation of
the cover plate. The "push-on", "thread-off'' design of the concealed cover plate
assembly allows easy installation of the cover plate after the system has been
tested and the ceiling finish has been applied, while also providing up to ½" (13
mm) of vertical adjustment. The cover assembly can be removed and reinstalled,
allowing temporary removal of ceiling panels without taking the sprinkler system out
of service or removing the sprinkler. The Electroless Nickel PTFE (ENT) coating
has been investigated for installation in corrosive atmospheres and is C-UL-US-EU
Listed as corrosion resistant as indicated in the Approval Charts. The ENT finish is
only available for the sprinkler assembly, the cover plate is not plated.
2. LISTINGS AND APPROVALS

Ordering Information: (Also refer to the current Viking price list.)
Viking Freedom® Residential Concealed Pendent Sprinkler VK494 and Cover Plate Assembly must be ordered separately:
Sprinkler: Order Sprinkler VK494 by first adding the appropriate suffix for the sprinkler finish and then the appropriate suffix for the
temperature rating to the sprinkler base part number.
Finish Suffix: Brass = A and ENT = JN
Temperature Suffix: 155 °F (68 °C) = B, 175 °F (79 °C) = D, 200 °F (93 °C) = E
For example, sprinkler VK494 with a Brass finish and a 200 °F (93 °C) temperature rating = Part No. 20759AE.
Cover Plate Assembly: Base Part No. 13504 (2-3/4" diameter), Base Part No. 13642 (3-5/16" diameter), or Base Part No. 15394

Sprinkler Cabinet: Part No. 01731 A (available since 1971)
4. INSTALLATION
Refer to appropriate NFPA Installation Standards.
5. OPERATION
During fire conditions, when the temperature around the sprinkler approaches its operating temperature, the cover plate detaches,
releasing the deflector. Continued heating of the exposed sprinkler causes the heat-sensitive liquid in the glass bulb to expand,
causing the glass to shatter, releasing the yoke and pip cap and sealing spring assembly .. Water flowing through the sprinkler
orifice strikes the deflector, forming a uniform spray pattern over a specific area of coverage determined by the water supply pres-
sure at the sprinkler to extinguish or control the fire.
6. INSPECTIONS, TESTS AND MAINTENANCE
