STI-3150 Weatherproof Pull Station Cover with Spacer

Product Description

The SAFETY TECHNOLOGY INT'L INC STI-3150 is a weatherproof protective cover designed for manual pull stations in fire alarm systems. Known as the Stopper II series, this cover fits over an existing pull station to shield it from accidental activation, tampering, and environmental exposure. When the cover is lifted or displaced, it triggers a local alarm, alerting personnel to unauthorized or unintentional contact. The included spacer accommodates pull stations that sit proud of the mounting surface, allowing a flush, secure fit. Installation is handled by licensed fire alarm technicians or qualified electrical contractors.

The STI-3150 is suited for both indoor and outdoor applications where pull stations require protection from weather, dust, or deliberate misuse. Typical install locations include school corridors, warehouses, manufacturing facilities, retail spaces, and exterior building entryways. The weatherproof rating makes it appropriate for covered outdoor mounting where the pull station is exposed to moisture, temperature swings, or airborne contaminants. The spacer included in the kit expands its compatibility to pull stations with varied projection depths.

Installation Notes

Installation should be performed by a licensed fire alarm technician or qualified electrician in accordance with NFPA 72 and applicable local codes. Disable or isolate the fire alarm zone before removing or installing the cover to prevent unintended alarm activation. Verify that the spacer is required for the specific pull station projection depth before final mounting. Confirm a secure fit and proper cover function before restoring the system to service.
