Mini Stopper^® II without Horn Flush Mount
STI-6540

This unique and patented device has been helping stop false fire alarms around the world for almost 30 years, without restricting legitimate alarms.

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).
