STI-1150 Pull Station Cover Stopper 2 Horn Outdoor Red

Product Description

The SAFETY TECHNOLOGY INT'L INC STI-1150 is an outdoor-rated flush-mount pull station cover designed to protect manual fire alarm pull stations from accidental activation and vandalism. Known as the Stopper 2 with Horn, this cover fits over standard pull stations and sounds an audible alert when the cover is lifted, giving facility staff an immediate warning before the alarm is triggered. It is finished in red for high visibility and meets the demands of exterior or harsh-environment installations. Fire alarm technicians and low-voltage contractors install this device as a protective layer over existing pull station hardware.

The STI-1150 is suited for outdoor applications where pull stations are exposed to weather, public access, or high-traffic conditions. Typical installations include building exteriors, covered walkways, parking structures, schools, and industrial facilities where accidental or malicious pull station activation is a concern. The flush-mount design keeps the cover profile low against the wall, making it compatible with standard single-gang pull station installations.

Installation Notes

Installation is typically performed by a licensed fire alarm technician or low-voltage contractor in accordance with NFPA 72 and local fire code requirements. Disable or isolate the fire alarm circuit at the panel before working on or around the pull station to prevent accidental system activation. Ensure the cover horn battery or power source is verified functional before closing out the installation. Follow the manufacturer data sheet for specific mounting hardware requirements and horn activation verification procedures.
