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) or 165F (74C), 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.
