The Stopper II is a robust protective cover designed to help prevent malicious or accidental false fire alarms, while allowing legitimate use of devices such as 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.
Design and Functionality
The Stopper II features a clear, tamperproof, UV-stabilised polycarbonate cover and frame that retrofits over the break glass call point. When lifted, an optional battery-powered integral sounder emits a piercing 95 dB or 105 dB alert (at 1 metre), immediately drawing attention to the area and deterring pranksters.
