Larger cover helps prevent malicious or accidental false fire alarms. The Stopper II is a unique device which has helped prevent false fire alarms around the world for more than 30 years, without restricting legitimate operation of devices such as fire alarm break glass call points. It is ideal for schools, colleges, hospitals, nursing homes, hotels, and all public buildings where there is a history or a threat of false fire alarms.
The Stopper II consists of a clear, tamperproof, 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 95 dB or 105 dB (at 1 metre). Immediate attention is drawn to the area and the prankster will either run or be caught.
