Fire Fighting Enterprises' Fireray Reflective combines an infrared transmitter and receiver into one unit. It projects an infrared beam onto a small prismatic reflector mounted on an opposite wall. The reflector returns the beam and the signal is analyzed for smoke presence. Automatic drift compensation prevents unwanted alarms due to dust or building movement. http://www.ffeuk.com/ DIRECT info #400
