This unique and patented device has helped stop false fire alarms around the world for over 30 years, without restricting legitimate alarms.
The STI 6540 consists of a clear, tamperproof, super tough polycarbonate cover and frame that fits over manual pull stations. Additional models are available with a built-in warning horn that sounds when cover is lifted to gain access to the pull station (see STI-6600). The STI 6540 offers excellent protection against physical damage (both accidental and intentional).
