The Stopper II is a larger, durable cover designed to reduce malicious or accidental false fire alarms without restricting legitimate use of devices such as fire alarm break glass call points. Trusted worldwide for over 30 years, it is ideal for schools, colleges, hospitals, nursing homes, hotels, and other public buildings where false alarms are a concern.
The Stopper II consists of a clear, tamperproof polycarbonate cover and frame that retrofits over the break glass call point. For added security, an optional integral battery-powered sounder emits a piercing 95 dB or 105 dB alarm (measured at 1 metre) when the cover is lifted. This draws immediate attention to the area, deterring pranksters and helping ensure accountability.
