Fire-lite Alarms by Honeywell W-H355 Wireless Heat Detector

Product Description

The FIRE-LITE ALARMS BY HONEYWELL W-H355 is a wireless fixed heat detector designed for use in fire alarm systems where smoke-based detection is not suitable. Fixed heat detectors activate when ambient temperature reaches a predetermined threshold, making them appropriate for environments such as dusty utility spaces, kitchens, and garages where smoke detectors would generate nuisance alarms. The W-H355 communicates wirelessly, eliminating the need to run dedicated detection wiring to the device location. Licensed fire alarm technicians and system integrators are the primary installers of this device.

The W-H355 is suited for residential and light commercial applications where a wired heat detector installation is impractical or cost-prohibitive. It integrates into compatible FIRE-LITE ALARMS BY HONEYWELL wireless fire alarm panel ecosystems. Typical installation scenarios include retrofit projects in existing structures where open-ceiling wiring is not feasible, as well as new construction where wireless system architecture has been specified by the engineer of record.
