Safety Technology Intl STI-6522-S Smoke Detector Cover

Product Description

The Safety Technology Intl STI-6522-S is a protective cover designed to guard smoke detectors from accidental or unauthorized activation. Known in the trade as a Bopper Stopper style cover, it fits over a standard smoke detector housing to prevent nuisance alarms caused by physical contact, tampering, or environmental disturbance. This type of accessory is commonly specified in commercial and institutional settings where false alarm reduction is a priority. Electricians and low-voltage technicians install these covers as part of a complete fire detection system installation or as an add-on during service calls.

The STI-6522-S is suited for use in schools, warehouses, gyms, and other facilities where smoke detectors are exposed to dust, debris, or deliberate interference. It is sold as a single unit and categorized as a keypad accessory within the fire and life safety product family. The cover does not interfere with the detection capability of the smoke detector it protects, allowing the unit to continue sensing smoke while shielding the device from physical impact.
