STI-6518 Pull Station Cover Plate

Product Description

The SAFETY TECHNOLOGY INT'L INC STI-6518 is a pull station cover plate designed to protect manual fire alarm pull stations from accidental activation. Commonly known as a Bopper Stopper, this cover plate mounts directly over a standard pull station and acts as a physical barrier that must be lifted or removed before the pull station can be operated. It is suited for commercial and institutional environments where false alarms are a concern. Installation is handled by fire alarm technicians or licensed electricians as part of a fire alarm system maintenance or upgrade.

This cover plate is appropriate for use in schools, warehouses, office buildings, and other facilities where manual pull stations are present and accidental or malicious activation needs to be discouraged. It does not interfere with intentional emergency use, as the cover is designed to be quickly moved when a genuine alarm situation occurs. The unit is sold individually and is a direct fit for compatible pull station housings.

Installation Notes

Installation should be performed by a licensed fire alarm technician or qualified electrician in accordance with NFPA 72 and applicable local fire codes. Before servicing or mounting the cover plate, ensure the fire alarm control panel is placed in a test or bypass mode per facility procedures to avoid an unintended alarm dispatch. Use appropriate fasteners for the pull station housing material. Verify that installation of the cover plate does not violate local fire marshal requirements for pull station accessibility.
