This unique and patented device has helped stop false fire alarms around the world for over 30 years, without restricting legitimate alarms. With a custom label the STI-6525 is also ideal for access controls, digital keypads, smaller manual pull stations, shutdown switches in computer rooms, workshops and much more.

STI-6525 is a protective cover for flush mount pull stations (surface - see STI 6535) that consists of a clear, tamperproof, super tough polycarbonate cover, weather gasket and frame. Cover contains no horn. Additional models (indoor only) are available with a built-in warning horn that sounds when cover is lifted to gain access to the pull station (see STI 6600)

This tough UV-stabilized cover helps extend the life and reliability of weather exposed manual pull stations and also guards against damage from dirt, grime and other harsh indoor conditions. STI-6525 is especially useful in increasing the lifespan of devices in saltwater areas or other severe environments.
