Safety Technology Intl STI-1221D Pull Station Stop Cover

Product Description

The SAFETY TECHNOLOGY INT'L INC STI-1221D is a stopper cover with a clear spacer designed to protect manual pull stations in fire alarm systems. It mounts over an existing pull station and acts as a deterrent against accidental or unauthorized activation. When the cover is lifted or removed, it triggers a local audible alert, signaling that the pull station has been accessed. Licensed fire alarm technicians and electricians typically install this device as part of a compliant fire protection setup.

This cover is suited for use in commercial and institutional environments where manual pull stations are at risk of accidental or malicious activation. Common installation locations include schools, hospitals, hotels, office buildings, and other high-traffic facilities. The clear spacer allows the underlying pull station to remain visible while the cover stays in place, supporting both code compliance and situational awareness for facility managers and safety personnel.
