Cover Plate Assembly: 

Base Part No. 16207 (3-5/16” diameter)  

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 Suffixes: White Polyester = M-/W, Chrome = F

Temperature Suffix: 139 °F (59 °C) = A, 165 °F (74 °C) = C

For example, cover 16207 with a White Painted finish and a 139 °F (59 °C) 

temperature rating = 16207MA/W. 

Available Finishes And Temperature Ratings:

 Refer to Table 1.

Accessories:

 (Also refer to the Viking website.)

Sprinkler Wrenches**:

A. Heavy Duty Wrench Part No. 16208W/R** (available since 2010)

B. Head Cabinet Wrench Part Number 16267

***

 (available since 2010) 

C. Optional Cover Plate Installer Tool Part No. 14867 (available since 2007)

 **Requires a ½” ratchet (not available from Viking).

***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. Continued heating of the 

exposed sprinkler causes the fusible element to disengage, releasing the sealing assembly. Water flowing  through the sprinkler 

orifice strikes the flow shaper, forming a uniform spray pattern over a specific area of coverage determined by the water supply 

pressure 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
