Reliable RFS Cover Plate Sprinkler Head Compatibility and Listings

This Sprinkler Head Cover Plate from Reliable may be listed by UL, FM, and/or other organizations depending on the sprinkler it’s being used with. It meets the requirements of a sprinkler assembly per NFPA 13, where approved by the local Authority Having Jurisdiction. It installs by simply pushing the cover into the sprinkler’s frame. The recommended hole diameter when installing sprinkler heads using this cover is 2-5/8 in. and protrudes 3/16 in. from the ceiling.

To remove your existing cover plate, gently twist the cover to the left while applying downward pressure by pulling gently as you turn.

When this fire sprinkler cover plate reaches its specified temperature of 135F (57C), 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.
