Note: Fitting Legend provides equivalent pipe lengths for fittings types of various diameters.
Equivalent lengths shown are standard for actual diameters of Sched 40 pipe and CFactors
of 120 except as noted with *. The fittings marked with a * show equivalent lengths values
supplied by manufacturers based on specific pipe diameters and CFactors and they require no
adjustment. All values for fittings not marked with a * will be adjusted in the calculation
for CFactors of other than 120 and diameters other than Sched 40 per NFPA.

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.
2. LISTINGS AND APPROVALS

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.

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
Copper = E-/B, Painted White = M-/W, Painted Ivory = M-/I, Painted Black = M-/B
Temperature Suffix: 135 °F/57 °C = A
For example, cover 13504 with a Polished Chrome finish and a 135 °F/57 °C temperature rating = 1350417A.
Available Finishes And Temperature Ratings: Refer to Table 1.

"Requires a'/2' ratchet (not available from Viking). `**Also optional for removal of the protective cap. Ideal for sprinkler cabinets.
Sprinkler Cabinet: Part No. 01731A (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
Refer to NFPA 25 for Inspection, Testing and Maintenance requirements.
7. AVAILABILITY
Viking Sprinkler Model VK494 is available through a network of domestic and international distributors. See The Viking Corporation
web site for the closest distributor or contact The Viking Corporation.
8. GUARANTEE
