  Availability 3 Days  ]

The Fireray 50/100RU system is a reflective beam smoke detector, which comprises of a single unit incorporating an infra-red transmitter and receiver. The signal generated in the transmitter element and reflected by the prism back to the receiver element is analyzed for the presence of smoke. The internal microprocessor determines an alarm condition when a predetermined level is reached.

The product is designed to be mounted so the beam will project between 19" (0.5 m) and 24" (0.6m) below and parallel to the ceiling. Lateral detection may be up to 30ft. (9.144m) on either side of the beam, providing a maximum total coverage area of up to 19,800 square feet (60ft. x 330ft. or 18.29m x 100m). 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.

Engineering Specification

The projected beam type smoke detector shall be a 4-wire 12/24 VDC device to be used with a separately supplied 4-wire control panel. The OBSD shall be listed to U.L. 268 and shall consist of an integrated transmitter and receiver. The detector shall operate between a range of 16.5 ft. to 330 ft. (5m to 100m). The temperature range of the beam shall be -4F to 131F (-20C to +55C). The beam detector shall feature automatic gain control which will compensate for gradual signal deterioration from dirt accumulation on the lenses. The unit shall be capable of mounting directly to the wall or to a surface back box. Testing shall be carried out by using a calibrated obscuration test filter. The Reflective beam type smoke detector shall be a FFE Ltd. Fireray 50RU (16.5ft-60ft / 5m-50m) or 100RU (160ft-300ft / 50m-100m).
