STI-13120EG Green Surface Mount Universal Stopper Cover

Product Description

The SAFETY TECHNOLOGY INT'L INC STI-13120EG is a green surface mount universal stopper designed to protect manual pull stations from accidental or unauthorized activation. This cover mounts directly over an existing pull station and serves as a physical deterrent against inadvertent pulls in low-risk or nuisance-prone areas. When the cover is lifted or displaced, it triggers an audible alert on compatible models, signaling that the protected device has been accessed. Fire alarm technicians and life safety contractors install this type of stopper as part of a complete fire alarm system maintenance or upgrade.

This stopper cover is suited for use in commercial, industrial, and institutional facilities where manual pull stations are at risk of accidental activation. Typical applications include schools, warehouses, retail spaces, and manufacturing environments. The green color designation is used to distinguish this unit from standard red stopper covers, making it appropriate for locations where color coding of fire alarm accessories is part of the facility management protocol. It is sold as a single unit and installs without requiring major modifications to the existing pull station assembly.
