Gamewell-FCI OSI-RI-GW is an intelligent addressable, single-ended reflective imaging beam smoke detector for large open areas with high ceilings, such as malls, aircraft hangars, arenas and concert halls. The detector is a combined transmitter/receiver aimed at a reflector, operating on infrared light obscuration. It is compatible with 7075 Series, S3 Series and E3 Series panels in Velociti mode.
A CMOS imager in a movable "eyeball" is aligned using four LED arrows, then locked with a slide lever under a paintable cover. The imager tracks the reflector to tolerate building movement, sets its sensitivity automatically from the reflector size, and compensates for long-term dust contamination.

Installation notes
- Spacing on smooth ceilings: 30 to 60 ft between beams, not more than half that to a sidewall (see NFPA 72).
- The built-in imager heater requires an external power supply.
- Remote test and reset from ground level with the RTS151 or RTS151KEY test station.
- Optional BEAMHKR reflector heater kit and 6500-MMK multi-mount bracket are available.

FAQ
Which panels is it compatible with?
Gamewell-FCI lists the OSI-RI-GW as compatible with 7075 Series, S3 Series and E3 Series fire alarm control panels in Velociti mode.
Is a reflector included?
Yes. The OSI-RI-GW is supplied as the intelligent imaging beam detector including the reflector. Only the head unit needs to be wired.
What range does it cover?
16 ft to 328 ft (5 m to 100 m) as standard; no separate long-range kit is required.
How many can go on one SLC loop?
Because of SLC current draw, Gamewell-FCI states this generally limits the detector to up to 4 per loop on a dedicated circuit on Gamewell-FCI panels.
