STI-1250 Stopper Ii Weatherproof Pull Station Cover

Product Description

The SAFETY TECHNOLOGY INT'L INC STI-1250 is a weatherproof pull station cover designed to protect manual fire alarm pull stations from accidental activation, tampering, and environmental exposure. Sold as a single unit, the STI-1250 fits over existing pull stations and provides a physical barrier without incorporating an audible horn. When the cover is lifted or displaced, it signals unauthorized or unintended contact. This cover is appropriate for indoor and outdoor installations where moisture, dust, or incidental contact poses a risk to pull station integrity. Licensed fire alarm technicians and electrical contractors typically handle installation as part of a fire alarm system maintenance or upgrade project.

The STI-1250 is suited for use in commercial, industrial, institutional, and light industrial environments where pull stations are exposed to weather, high-traffic areas, or locations prone to accidental contact. Typical applications include covered exterior entryways, loading docks, warehouses, schools, and manufacturing facilities. The weatherproof construction makes it appropriate for installations where the pull station may be exposed to rain, humidity, or temperature cycling. It is used without an integrated horn, making it the correct choice when a silent deterrent or cover-only application is required.

Key Features

• Weatherproof construction suitable for outdoor and harsh indoor environments
• Covers existing pull stations without requiring modification to the pull station itself
• Horn-free design for applications where audible alert at the cover is not required
• Deters accidental activation and tampering in high-traffic or exposed locations
• Sold as a single unit for straightforward replacement or new installation

Compatibility

Designed as an OEM-style protective cover for standard manual fire alarm pull stations in commercial and institutional fire alarm systems. Refer to the manufacturer documentation for specific pull station model fitment before ordering.

Installation Notes

Installation should be performed by a licensed fire alarm technician or qualified electrical contractor in accordance with NFPA 72 and applicable local codes. Disable or notify the monitoring station before working on any active fire alarm circuit to prevent accidental dispatch. Verify that the pull station dimensions are compatible with the STI-1250 cover prior to mounting. Do not permanently obstruct the pull station mechanism in any way that would prevent operation in a fire emergency.
