Kidde | Fireray One Auto-Aligning Reflective Beam Smoke Detector with Long Range Reflector Kit, 120M (394 ft) Range, UL/ULC | KC1-120

The Fireray One KC1-120 pairs the standard Fireray One beam detector with the Long Range Reflector Kit (1010-000) pre-included, extending coverage to 394 feet (120m) across a single beam path. Mount the detector on one wall and the reflector on the opposite wall, aim the integrated laser, and the motorized optics handle fine alignment automatically. One person, 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 on long spans. 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 large open-area facilities where a long-range beam pays for itself in fewer detector heads. UL and ULC listed.

Key features

• 394 ft (120m) detection range with the Long Range Reflector Kit included in the box
• 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
• 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. The Long Range Reflector Kit (1010-000) is included with this SKU - no separate order needed for 120m coverage.
