STI-3150CR Weather Stopper Ii Pull Station Cover No Horn

Product Description

The SAFETY TECHNOLOGY INT'L INC STI-3150CR is a Weather Stopper II pull station cover designed to protect manual fire alarm pull stations from environmental damage, tampering, and accidental activation. Sold as an individual unit, this cover fits small-profile pull stations and is specified without an integrated horn. It is typically installed by fire alarm technicians, electricians, and security system contractors in applications where the pull station requires environmental or vandal protection without an audible alert at the device itself.

The STI-3150CR is suited for indoor and light-duty outdoor installations where small-format pull station covers are required. Common deployment locations include commercial buildings, schools, warehouses, and industrial facilities. This model is the no-horn variant, making it appropriate for locations where a separate notification appliance circuit handles audible alarming and a local sounder at the cover is not needed or desired.

Key Features

• Weather Stopper II series cover provides environmental and tamper protection for pull stations
• No-horn configuration for installations where local audible alert is not required
• Small profile sizing for compatibility with compact pull station footprints

Compatibility

Installation Notes

Installation is typically performed by a licensed fire alarm technician or electrician in accordance with NFPA 72 and local authority having jurisdiction requirements. Before servicing or replacing any pull station cover, ensure the fire alarm control panel is placed in test mode to prevent unintended alarm activations. Secure all mounting hardware fully and verify the cover does not obstruct the pull station actuator travel. Consult the fire alarm system documentation to confirm the no-horn variant is appropriate for the specific zone configuration.
