Apollo XPander Optical Smoke Detector XPA-OP-12034-APO XPander optical detectors are recommended for use as general purpose smoke detectors for early warning of fire in most installations. XPander optical detectors operate on the well-established light scatter principle. The optical design of the XPander optical detector allows it to respond to a wide spectrum of fires. The detector is calibrated so that XPander is highly reliable in detecting fires but has enhanced immunity to false alarms. The stability of the detector in terms of high reliability and low false alarm rate is further increased by the use of algorithms to decide when the detector should change to the alarm state. This removes the likelihood of a detector producing an alarm as a result of smoke from smoking materials or from another non-fire source. Operation Photo-electric detection of light scattered by smoke particles over a wide range of angles. The optical arrangement comprises an infra-red emitter with a prism and a photo-diode at 90 to the light beam with a wide field of view. The detectors microprocessor uses algorithms to process the sensor readings. XPander Information XPander incorporates entirely new designs with respect to the wireless communication system. A Radio Interface is connected to the loop. It communicates with the control panel using the Apollo addressable two-wire power and communications system. The interface communicates with the detection and alarm signalling devices by means of radio waves. The detectors are multistate in that they report normal, pre-alarm, fire or fault states to the radio base which transmits the information to the interface. The detectors incorporate drift compensation and report any compensation limit occurring. The radio bases and signalling devices are addressable and use a pre-set analogue value to report via the XP95 or Discovery protocol. Apart from normal and fire the bases can send pre-set analogue values to indicate low battery, detector contaminated, detector tamper and low signal strength fault conditions.
