Safety Technology Int'l Inc STI-9840 Steel Wire Cage

Product Description

The SAFETY TECHNOLOGY INT'L INC STI-9840 is a steel wire protective cage designed to guard beam smoke detectors, specifically the Fireray 5000 series, from accidental impact and tampering. Installed in commercial and industrial environments where detectors are exposed to physical activity, the STI-9840 provides a durable barrier without obstructing the detector's optical path. It is a single-unit accessory installed by fire alarm technicians or licensed electrical contractors during initial system setup or as a retrofit to existing installations.

This cage is suited for environments where beam detectors are mounted in areas subject to foot traffic, equipment operation, or maintenance activity that could inadvertently damage the detector head or reflector. Typical applications include warehouses, gymnasiums, open manufacturing floors, and large commercial atriums where the Fireray 5000 beam detector is part of the fire alarm system. The STI-9840 secures over the detector to reduce nuisance damage and extend service life.
