Esser 761416 Fireray ONE Self-Aligning Beam-Type Smoke Detector, 1 Prism

Fireray ONE, presented by Honeywell under the Esser brand, is a linear smoke detector comprising a detector head and a prism reflector positioned opposite it; it operates across openings between 5 and 50 meters. The visible laser from the device panel is directed at the prism, and alignment is automatically completed with one button press; a single person can complete installation without special tools. Light cancellation technology prevents false alarms caused by daylight sources, while building motion tracking continuously maintains alignment.
