XP95 Multisensor detector
The XP95 multisensor detector is included in the BOSEC B-9072-FD-954 - EN54-13 certificate of the MD2400(L) analogue addressable fire detection system.
The XP95 multisensor detector is composed of a white, flame-retardant polycarbonate housing. The detector is equipped with two colourless LED, emitting red light in case of an alarm, and a unique addressing mechanism, the XPert card. The XPert card is placed in the base of the detector, while the base is completely free of electronics.
The XP95 multisensor detector combines optical smoke and temperature sensors whose outputs are combined to give the final analogue value. The signals from the optical smoke sensing element and the temperature sensor are independent, and represent the smoke level and the air temperature respectively in the vicinity of the detector.
- sensitive to a wide range of fires
- well suited to environments such as hotel bedrooms
- unaffected by wind or atmospheric pressure
The XP95 multisensor detector contains an optical smoke senor and a thermistor temperature sensor.
The multisensor construction is similar to that of the optical detector but uses a different lid and optical moulding to accomodate the thermistor temperature sensor.
The signals from the optical smoke sensing element and the temperature sensor are independent and represent the smoke level and the air temperature respectively in the vicinity of the detector.
The detectors microcontroller processes the two signals. The temperature signal processing extracts only rate of rise information for combining with the optical signal. The detector will not respond to a slow temperature increase - even if the temperature reaches a high level. A large sudden change in temperature can however cause an alarm without the presence of smoke if sustained for 20 seconds.
The processing algorithms in the multisensor detector incorporate drift compensation.
The sensitivity of the detector is considered the optimum for most general applications.
