The larger cover is designed to reduce both deliberate misuse and accidental activation of fire alarms. The Stopper II has been a trusted solution for over 30 years, helping to minimise false alarms worldwide without interfering with the proper use of devices like break glass call points. It’s particularly well suited for environments such as schools, colleges, hospitals, care homes, hotels, and other public buildings where false alarms are a concern.
The Stopper II features a clear, tamper-resistant polycarbonate cover and frame that fits neatly over an existing break glass call point. When the cover is lifted to access the alarm, an optional battery-powered sounder emits a loud 95 dB or 105 dB alert (measured at 1 metre), drawing immediate attention and discouraging misuse.
