STI Call Point Stopper With Optional Sounder

Protective cover to help stop malicious or accidental false fire alarms. This unique device has been helping stop false fire alarms around the world for decades, without restricting legitimate operation of devices such as fire alarm break glass call points. Ideal for schools, colleges, hospitals, nursing homes, hotels and all public buildings where there is a history or a threat of false fire alarms.

How It Works

The Stopper consists of a clear, tamper-proof, tough polycarbonate cover and frame that retrofits over the break glass call point. When lifted to gain access to the break glass, its optional battery powered integral sounder emits a piercing 96dB (at 1 metre). Immediate attention is drawn to the area and a prankster will either run or be caught.
