STI 13220NW Universal Stopper Dome Cover, Surface Mount, Label Hood with Horn, No Label, White

Protect critical alarm devices and access controls from vandalism and accidental activation with the Safety Technology International STI-13220NW Stopper Dome protective cover. This durable polycarbonate security cover delivers reliable physical protection for pull stations, intercoms, keypads and emergency buttons without impeding legitimate use. When the cover is lifted, a built-in 105 dB horn sounds to immediately alert staff and deter tampering—helping reduce false alarms and speed incident response in monitored environments. The surface-mount design includes conduit knockouts for quick wiring and fits most standard pull stations (compact dimensions roughly 5.42 x 4 x 3.88 in), making it ideal for retrofits or new installations. UL/cUL Listing and ADA compliance provide peace of mind for facilities managers specifying code-compliant protective covers. Engineered for both indoor and outdoor security, the STI-13220NW supports your surveillance and monitoring strategies by protecting devices that trigger alarms and notifications. Order the STI Stopper Dome cover to strengthen perimeter protection and minimize nuisance activations in schools, hospitals, retail locations and public facilities.
