This patented protective cover has been helping stop false fire alarms around the world for over 30 years, without restricting legitimate alarms. Ideal for schools, hospitals, nursing homes, stores, hotels and public buildings of almost every kind.
STI-1250NR consists of a clear, tamperproof, super tough polycarbonate cover, frame and gasket that fits over most manual pull stations. The cover is connected to the frame by a cable. When the cover is lifted, it hangs off of the frame until the cover is snapped back onto the frame.
This tough UV-stabilized cover helps extend the life and reliability of weather exposed manual pull stations and also guards against damage from grime and other harsh indoor conditions. Using the same super tough cover as the Stopper II, but without the warning horn, it is especially useful in increasing the lifespan of devices in saltwater areas or other severe environments.
