This White 135F (57C) Cover Plate Assembly for Viking Mirage Large Diameter Fire Sprinklers is listed by UL, FM, and/or other organizations depending on the sprinkler. When this white fire sprinkler cover plate reaches a specified temperature the solder holding the plate's decorative exterior on the frame melts, and the two separate.
For many cover plates, the rated temperature is at least 20F (6.7C) cooler than the sprinkler head's activation temperature, which ensures that the cover plate detaches early enough to allow the sprinkler to activate on time. However, each manufacturer's product line varies slightly and cover plate temperatures may be closer to or further away from the fire sprinkler's activation temperature. Use only the cover plate approved by the manufacturer for your specific sprinkler.
Fire Sprinkler Helpful Tips:
Tip 1:
When replacing cover plates it is important to purchase replacements from the same manufacturer as the fire sprinkler. Each manufacturer's plate is a little different in size, color, and so on. The manufacturer and temperature of a cover plate is printed on the base of the plate. To view this information, remove the cover plate. Most cover plates are either twist off or pull off.
Tip 2:
Any modifications or replacements to a fire sprinkler system should be performed by qualified professionals.
Tip 3:
National Fire Protection Association (NFPA) guidelines state that spare fire sprinkler heads and a wrench should be accessible at all times in a facility with a commercial fire sprinkler system installed. Often, state regulations also apply. Check with your local fire department.
Tip 4:
All fire sprinkler systems should be visually inspected (often) and professionally inspected (annually).
