Mini Stopper II® without Horn with Spacer
STI-6545


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-6545 is also ideal for access controls, digital keypads, smaller manual pull stations, shutdown switches in computer rooms, workshops and much more.

STI-6545 consists of a clear, tamperproof, super tough polycarbonate cover, frame and conduit spacer that is designed for surface mount manual pull stations (flush - see STI-6540). 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- STI-6605). The STI-6545 offers excellent protection against physical damage (both accidental and intentional).
