STI 6545 Mini Stopper II without Horn with Spacer

Special Order


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 - 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 (STI 6605). The STI-6545 offers excellent protection against physical damage (both accidental and intentional).
