The Euro Stopper is a tamperproof protective cover designed to prevent malicious or accidental false fire alarms while ensuring legitimate operation of fire alarm devices such as break glass call points. Sleeker and more compact than previous Stopper® models, it incorporates a new hinge design that enhances durability, strength, and reliability, making it ideal for schools, colleges, hospitals, nursing homes, hotels, and other public buildings where false alarms are a concern. The Euro Stopper features a clear, tough polycarbonate cover and frame that retrofits over the break glass call point. When lifted, an optional battery-powered sounder emits a 96 dB alarm (at 1 metre), drawing immediate attention to the area and deterring pranksters. The Glow Guide material embedded in the frame perimeter illuminates in the dark, making the call point easier to locate in unlit areas. The Multi Kit includes 1 Euro Stopper frame with Glow Guide, 2 coloured housing shells (red & green), 1 break seal, and 2 label sheets in 13 languages. Available with or without sounder. For versions with sounder & relay, sounder & wireless, or sounder, wireless & relay, it is recommended to purchase the non-sounder version first and then add the appropriate accessories. Key features include prevention of malicious or accidental false alarms, three-year guarantee on polycarbonate (one year on electronic components), glow-in-the-dark visibility, tough polycarbonate housing that withstands severe knocks, simple 4-fix installation that retrofits existing devices, accommodation for flush or surface mount call points, typical working range of -40°C to 121°C (-40°F to 250°F), availability with 96 dB integral sounder (3V lithium battery) or optional 12-24 VDC powered units, one break seal supplied per unit with additional break seals available, multiple colour options (non-Multi Kit versions), and optional transmitter and sounder integration allowing local and remote alert via 8-Channel Receiver (STI-34108).
