Direct replacement for STI-6525 and STI-6540
This indoor/outdoor unique 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 or 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 message hood. Other mounting options include a surface spacer with conduit knockouts or a waterproof Type 4X enclosed back box (Type rating pending). The cover is also available with horn. The Universal Stopper is designed to comply with ADA and is less than 4 inches in depth. Universal Stopper has the same footprint as the Mini Stopper® , but has a larger interior and can accommodate most dual action pull stations.
