STI-1200 Stopper II without Horn: Flush Mount

This unique and patented device has been helping stop false fire alarms around the world for more than 20 years, without restricting legitimate alarms.

Stopper II consists of a clear, tamperproof, super tough polycarbonate shield and frame that fits over 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. 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-1100).
