Order the sprinkler assembly (includes sprinkler and adapter pre-assembled, with a protective plastic cap covering the unit) by
adding the appropriate suffix for the sprinkler temperature rating, and then the suffix for the length ("A" dimension) to sprinkler
base part number (Order in a specific length noted as the "A" dimension (see Figure 4).
The "A" dimension is the distance from the face of the fitting (tee) to the desired finished surface of the ceiling. These sprinklers are
listed and approved in lengths from 4" to 48-1/4" (102 mm to 1,226 mm).
Lengths exceeding the standard length are available, with no approvals, on a "made-to-order" basis up to 65-1/4" (1,657 mm).
Contact the manufacturer for more information.
Temperature Suffix: 155 °F (68 °C) = B, 175 °F (79 °C) = D, 200 °F (93 °C) = E
For example, sprinkler VK192 with 1" NPT Threads, a 155 °F (68 °C) temperature rating, and "A" length of 10" = Part No.

Cover Plate Assembly: Base Part No. 12381
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, Painted White = M-/W, Painted Ivory = M-/I, Painted Black = M-/B
Temperature Suffix: 135 °F (57 °C) = A , 165 °F (74 °C) = C
For example, cover 12381 with a Polished Chrome finish and a 135 °F (57 °C) temperature rating = 12381FA.
Available Finishes And Temperature Ratings: Refer to Table 1.
Accessories: (Also refer to the "Sprinkler Accessories" section of the Viking data book.)
Sprinkler Wrenches:
Part No. 07565W/B** (available since 1991)
**A ½" ratchet is required (not available from Viking).
4. INSTALLATION
Refer to appropriate NFPA Installation Standards. Concealed dry sprinklers are NOT recommended for freezers or cold storage
applications that require sealing methods which could interfere with air flow through the sprinkler cover plate and body.
5. OPERATION
During fire conditions, when the temperature around the sprinkler approaches
its operating temperature, the cover plate detaches. Continued heating of
the exposed sprinkler causes the heat-sensitive liquid in the glass bulb to
expand and the bulb to shatter, releasing the internal parts to open the
waterway. Water flowing through the sprinkler orifice strikes the sprinkler
deflector, forming a uniform spray pattern to extinguish or control the fire.
6. INSPECTIONS, TESTS AND MAINTENANCE
Refer to NFPA 25 for Inspection, Testing and Maintenance requirements.
