Safety Technology Int'l Inc STI-9604 Heat Detector Guard

Product Description

The SAFETY TECHNOLOGY INT'L INC STI-9604 is a steel wire stopper guard designed to protect heat detectors from accidental damage, vandalism, and tampering. The guard mounts over an installed heat detector and forms a physical barrier that keeps the device intact while still allowing airflow and heat to reach the sensing element. This type of protective cage is a standard fixture in commercial and industrial fire alarm installations where detectors are exposed to high-traffic areas, mechanical impact, or unauthorized contact. Installation is typically performed by licensed fire alarm technicians or electricians.

The STI-9604 is suited for use in warehouses, gymnasiums, parking structures, manufacturing facilities, and other environments where ceiling-mounted heat detectors are at risk of physical contact. The steel wire construction provides durable protection without obstructing the detector's sensing capability. This stopper is sold as a single unit and is intended for use with compatible ceiling-mounted heat detectors in fire protective applications.

Key Features

• Steel wire construction provides physical barrier against impact and tampering
• Open wire design maintains airflow to the heat detector sensing element
• Compatible with ceiling-mounted heat detector installations
• Single-unit packaging for straightforward replacement or new installation
• Designed for use in fire protective cage applications

Compatibility

Designed as an OEM-style protective guard for ceiling-mounted heat detectors in commercial and industrial fire alarm systems. Confirm detector head and ceiling mount dimensions before ordering.

Installation Notes

Installation should be performed by a qualified fire alarm technician or licensed electrician in accordance with NFPA 72 and local fire code requirements. Power down or disable the fire alarm circuit zone before handling the detector or mounting hardware. Ensure the guard is seated securely and does not contact or depress the detector's sensing element. Verify that the installed guard does not impede detector sensitivity per the manufacturer's listed requirements.
