Fireray Infrared Optical Beam Smoke Detectors

The Fireray End to End Infra-red Optical Beam Smoke Detector (OBSD) has been designed using the latest optical technology, incorporating modern industrial, electronic and software techniques. This detector offers cost-effective protection of large, open area spaces with high ceilings. It is also very suited to applications where access to ceiling mounted smoke detectors presents practical difficulties.

Fireray Smoke Detectors are ideal for applications where line of sight for the IR (infra-red) detection path is narrow and where the building structure uses reflective surfaces. It has also been designed to be aesthetically pleasing and thus can equally suit modern architectural buildings as well as historical sites, particularly where ornate ceilings exist.

The projected beam type smoke detector shall be listed to U.L. 268 and consists of up to two transmitters, two receivers and a single low-level remote control unit. The detector operates between a range of 16.5 393 ft. (5m to 120m). The temperature range of the system is -4°Fto 131°F (-20°C to 55°C). The receiver includes an integral built-in laser pointer to assist in optimum alignment.

The beam detector featured automatic gain control, which will compensate for gradual signal deterioration from dirt accumulation on the lenses. The receiver heads incorporate a Wide Field of View to ensure the unit is always receiving maximum signal available. The system includes a low level remote display and control unit with LCD read-out for set-up, reporting and testing of up to 2 separate sets of heads. The system is capable of sending separate Trouble and Alarm signals for each of the sets of heads. The system features programming alarm thresholds of 25% to 60% in 1% increments. The system is capable of programming delay to fault and delay to alarm from 2 seconds to 30 seconds in 1 second increments.

Test and acceptance of the system is carried out by using the UL/ULC-approved internal electronic obscuration fire test. The projected beam type smoke detector is a 4-wire 24VDC device used with a Nationally Recognized Testing Laboratory’s Listed and separately supplied4- wire control panel. The End to End beam type smoke detector is a FFE Ltd Fireray 3000.
