Silent Knight OSI-RI-SK — intelligent single-ended reflective imaging beam smoke detector, for addressable Silent Knight panels.
Transmitter and receiver sit in one head that projects an infrared beam at a passive reflector and alarms on obscuration, so one wired device covers open volumes where spot detectors are impractical to service. A CMOS imager in a movable eyeball finds the reflector and keeps tracking it as the structure shifts, with four LED arrows guiding alignment.
- Protection range 16 ft to 328 ft (5 m to 100 m), no long-range kit
- 12° field of view; 50° horizontal and 20° vertical adjustment
- 15 to 32 VDC; 14 mA standby and 15 mA alarm at 24 VDC
- Obscuration levels 25%, 30%, 40% and 50%, set automatically
- UL listed 32°F to 100°F; imager heater built in
- Detector 6" × 10" × 4.5"; reflector 9.06" × 7.87"
- UL S911, FM PR449231, CSFM 7260-0559:0515
The same detector is badged OSI-RI-FL for Fire-Lite and OSI-RI-GW for Gamewell-FCI, so confirm the panel brand first. BEAMHKR reflector heater, RTS151 and RTS151KEY test stations and the 6500-MMK mount are ordered separately.
