Smoke detector covers and fire alarm covers are the small parts nobody thinks about until one is cracked, painted over or missing, and they do several different jobs.
Dust covers are the caps that keep drywall dust and construction debris out of a detector head while a building is being finished; leaving a head uncovered through construction is a common cause of nuisance alarms and early sensor failure. Device covers and cover plates are the finished trim for notification appliances, modules and mounting plates, supplied in red or white and lettered FIRE, ALERT or left blank. Protective guards and cages shield pull stations, horns, strobes and detectors from impact and tampering in gyms, corridors, warehouses and detention areas. Weatherproof covers and backboxes suit devices mounted outdoors or in wet locations.
Whether you need a smoke detector cover, a duct detector cover, an appliance cover plate or a device guard, we stock them from Simplex, System Sensor, STI, Silent Knight and Air Products and Controls, including old style and discontinued fire alarm covers.
