Product DescriptionThis protective cover with an integrated attention horn is designed to safeguard fire alarm pull stations from accidental or intentional misuse while keeping the station fully visible and immediately accessible during real emergencies. Its clear high strength polycarbonate construction provides exceptional impact resistance and resists discoloration over time which makes it suitable for schools hospitals transportation hubs commercial buildings and other high traffic environments where equipment is vulnerable to frequent contact. When the cover is lifted the internal horn emits a loud alert that draws instant attention to the area which serves as a strong deterrent against tampering and reduces false alarm incidents that disrupt building operations and emergency response procedures. The unit mounts neatly over standard pull stations with a flush fit that maintains a clean appearance on the wall while the built in hinges and molded edges allow smooth operation for authorized users. The horn is powered by a long lasting internal battery and the overall design supports routine inspections without interfering with system wiring or detector access. By adding a secondary layer of protection around existing fire alarm equipment this device helps preserve system integrity reduce nuisance activations and enhance overall life safety readiness throughout the facility.
