STI 13220CG Universal Stopper Dome Cover Flush Mount, Label Hood with Horn, Custom Label Blue

Protect critical alarm and access devices without impeding legitimate use with the Safety Technology International STI-13220CG Stopper dome security cover. Designed for commercial and institutional environments, this protective cover shields dual-action pull stations, keypads, intercoms and emergency buttons from vandalism, accidental damage and harsh outdoor conditions while keeping them accessible in an emergency. The polycarbonate dome delivers impact- and weather-resistant performance, UV stabilization and long-term durability. When the cover is lifted, a 105 dB audible horn activates to draw immediate attention and discourage false activations—helping security and facilities teams reduce nuisance alarms and accelerate incident response. Sized to fit most pull stations and available in surface, flush or waterproof backbox mounts, the STI-13220CG is UL/cUL listed and ADA-compliant for code-conscious installations. Ideal for schools, hospitals, hotels and retail facilities, this cover integrates smoothly into existing security and surveillance systems and supports effective monitoring and incident management.
