Aritech FD2710R 2000 Series Addressable Reflective Beam Detector 100m
Aritech FD2710R 2000 Series Addressable Reflective Beam Detector 100mThe FD2705R and FD2710R provides an integral loop powered analogue addressable reflective beam detector up to 100m distance. Wiring is restricted to a minimum as the transmitter and receiver are in the same housing. The detector is very easily aligned by means of checking the alignment LEDs. Easy alignment ensures optimum operation both electrically and mechanically. The unit is easily tested using the graduated obscuration test card supplied.The low power consumption of the units allows multiple beams to be powered on the same loop without compromising the systems autonomy. The FD2705R and FD2710R consist of an infrared transmitter and receiver in one single compact housing. The infrared signal is reflected by a prism and analysed for smoke presence. It is particularly designed to be use where point smoke detectors are not practical due to height or inaccessibility.The FD27xxR series units are loop powered for connection to 12002000 series fire panels. They use the Aritech 2000 series protocol. Various alarm thresholds may be selected from to suit the environment. If the signal reduces to below the selected threshold and is present for 10 seconds a fire condition is signalled. If the infrared beam is obscured rapidly to a level of 90 or greater for 10 seconds a fault condition is signalled. The detector monitors long term degradation of signal strength caused by component ageing or build-up of dirt on optical surfaces.Key FeaturesLoop Powered2000 series protocolArea coverage up to 600 mRange from 5 - 50 m and 50 - 100 mUp to ceiling heights of 25 mLow current consumption3 selectable alarm thresholdsSelf-check and automatic contamination compensationAutomatic discrimination between fire and faultVertical or horizontal mountEasy wiring and unique alignmentMicroprocessor controlledConforms to BS5839 part 5 and EN54
