Kidde | Fireray One Auto-Aligning Reflective Beam Smoke Detector, 50M (164 ft) Range, UL/ULC | KC1-50

The Fireray One KC1-50 covers open areas up to 164 feet with a single reflective beam path and aligns itself in under a minute. Mount the detector on one wall and the prismatic reflector on the opposite wall, aim the integrated laser, and the motorized optics handle fine alignment automatically. One person, no specialist tools, no ladder time spent chasing signal strength.

Built for the commercial installer

Building Movement Tracking continuously compensates for structural shifts over time, eliminating re-alignment callbacks that plague conventional beam detectors. The detector draws just 5 mA from any 14-36 VDC source, making it compatible with standard fire alarm panel auxiliary outputs. IP55-rated polycarbonate housing handles dusty warehouses, atriums, and loading docks. UL and ULC listed.

Key features

• One Minute Auto-Alignment: motorized optics find optimal beam path after initial laser aim, no manual tweaking
• Building Movement Tracking: continuous motorized micro-adjustments compensate for structural shifts without service calls
• 164 ft detection range standard, extendable to 394 ft with the optional Long Range Kit (order KC1-120 for the kit pre-included)
• IP55 weather rating for dusty, humid, or temperature-variable commercial environments
• Four programmable alarm thresholds from 25% (fastest response) to 85% (highest false-alarm immunity)
• 5 mA normal draw from 14-36 VDC - runs off panel aux power with headroom to spare

System requirements

Requires a compatible conventional fire alarm control panel with supervised zone input. The detector connects to the panel's initiating device circuit and draws power from a 14-36 VDC auxiliary output. Reflective prism panel included.
