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
1/2” (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.

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, 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

Specify finish and temperature rating of the cover plate assembly by adding the appropriate suffixes for the finish and the cover
temperature rating to the base part number:
Finish Suffix: Polished Chrome = F, Brushed Chrome = F-/B, Bright Brass = B, Antique Brass = B-/A, Brushed Brass = B-/B, Brushed

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-
