Apollo XP95 Heat Detector High Temperature 55000-401APO
Apollo XP95 Heat Detector High Temperature 55000-401APOThe XP95 Heat Detector monitors temperature by using a single thermistor which provides a count output proportional to the external air temperature. The XP95 range features two heat detectors standard and high temperature. The standard heat detector is classified as an A2S device and will report an alarm at 55C. The high temperature detector classified as a CS device will report an alarm at 90C.OperationThe XP95 heat detectors have a low air flow resistance case made of self-extinguishing white polycarbonate. The devices monitor heat by using a single thermistor network which provides a voltage output proportional to the external air temperature. The standard heat detectors 55000-400 and 55000-420 respond to increasing air temperature in such a way that they are classified as an A2S device. Both devices will give 55 counts at 55C. A high temperature CS heat detector 55000-401 which can be installed in a typical ambient temperature of 55C is available. This device will give 55 counts at 90C.ApplicationThe choice of detector from the XP95 range follows the well-established principles of system design. That is the optimum detector type will depend on the type of fire risk and fire load and the type of environment in which the detector is sited. For general use smoke detectors are recommended since these give the highest level of protection. Smoke detectors from the XP95 range may be optical or multisensor types. It is generally accepted that ionisation types have a high sensitivity to flaming fires whereas optical detectors have high sensitivity to smouldering fires.Key FeaturesIdeal in environments that are dirty or smoky under natural conditionsWell suited for warehouses loading bays and car-parksUnaffected by wind or atmospheric pressure
