STI-1100CP6 Pull Station Cover Stopper Ii 6 Pack

Product Description

The SAFETY TECHNOLOGY INT'L INC STI-1100CP6 is a contractor six-pack of Stopper II pull station covers designed to protect manual fire alarm pull stations from accidental or unauthorized activation. Each cover mounts over an existing pull station and triggers a local alarm when lifted, alerting personnel to any tampering before a false alarm occurs. This product is intended for installation by licensed fire alarm technicians and electrical contractors working on commercial or institutional life-safety systems. The six-pack format is suited for multi-zone projects or facilities requiring coverage across several alarm initiation devices.

The STI-1100CP6 contractor pack is used in commercial buildings, schools, healthcare facilities, and industrial environments where false fire alarm activations represent a significant operational and safety concern. The Stopper II cover is a widely recognized solution for reducing nuisance activations on manual pull stations. Each unit in the pack ships ready to install, making this format efficient for contractors outfitting multiple floors or zones in a single project.

Key Features

• Six Stopper II pull station covers included in a single contractor pack
• Local alarm sounds when cover is lifted, providing tamper deterrence without disabling the pull station
• Designed to reduce false fire alarm activations in high-traffic or high-risk areas
• OEM-style fit over standard pull station form factors
• Contractor pack quantity reduces per-unit handling and ordering overhead on larger jobs

Compatibility

Designed as an OEM-style replacement and new-installation cover for standard manual fire alarm pull stations in commercial life-safety applications. Verify pull station dimensions against Stopper II specifications prior to installation.

Installation Notes

Installation should be performed by a qualified fire alarm technician or licensed electrician in accordance with NFPA 72 and applicable local codes. Disconnect or isolate the fire alarm control panel zone before mounting or adjusting covers to prevent unintended alarm signals during installation. Confirm that the cover does not obstruct the pull station handle travel or impede emergency operation after installation. Follow the manufacturer data sheet for mounting hardware guidance specific to each unit.
