Fire-Lite OSI-90-L8 Xtralis Imager Beam Detector, 80 Degree

Protect large, open spaces quickly and confidently with the Fire-Lite Alarms by Honeywell OSI-90 imager beam detector — a duct & beam smoke detector engineered for early warning and dependable monitoring. Using dual-wavelength LED optical imaging and a CMOS imaging chip, the OSI-90 identifies smoke earlier while rejecting transient dust, steam and building movement that cause false alarms. The unit supports long-range coverage up to 492' (150 m) and operates on standard 24V DC power for straightforward integration into existing fire and security systems. Wall-mount form factor and wide adjustment angles simplify alignment and reduce installation time, while on-board event logging speeds diagnostics and lowers lifecycle costs. Ideal for airports, warehouses, convention centers, stadiums and other high-ceiling applications where reliable surveillance and fire monitoring are critical.
