The Fireray ® 3000 system is an end to end infrared optical beam smoke detector (OBSD) which 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.
The product is designed 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. For installations complying with UL268/NFPA72, the maximum distance of Detector and Reflector from the ceiling must be 10% of the distance between floor and ceiling.
The projected beam type smoke detector shall be listed to U.L. 268
and shall consist of up to two transmitters, two receivers and a single
low level remote control unit. The detector shall operate between a
range of 16.5 ft. to 393 ft. (5m to 120m). The temperature range of
the system shall be -4°F to 131°F (-20°C to 55°C). The receiver shall
include an integral built-in laser pointer to assist in optimum alignment.
The beam detector shall feature automatic gain control, which will
compensate for gradual signal deterioration from dirt accumulation on
the lenses. The receiver heads shall incorporate a Wide Field of View
to ensure the unit is always receiving maximum signal available. The
system shall include 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 shall be capable of sending separate Trouble and
Alarm signals for each of the sets of heads. The system shall be capable
of programming alarm thresholds of 25% to 60% in 1% increments.
The system shall be capable of programming delay to fault and delay to
alarm from 2 seconds to 30 seconds in 1 second increments.
