This indoor polycarbonate cover helps stop false fire alarms without restricting legitimate operation of pull stations. It protects devices such as dual action pull stations, keypads for entry systems, intercom stations, emergency buttons, electrical light switches, duplex plugs, etc. The strong, durable construction takes the toughest knocks while it guards against accidental or intentional physical damage.
This Universal Stopper is a clear, flush mount cover with a red horn housing, alarm and fire label. Cover is designed to comply with ADA and is less than 4 inches in depth. Other mounting options include a surface spacer with conduit knockouts or a waterproof Type 4X enclosed backbox (Type rating pending). Universal Stopper has the same footprint as the Mini Stopper , but has a larger interior and can accommodate most dual action pull stations.
