    Apollo XP95 Heat Detector (High Temperature)

    The 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 55°C. The high temperature detector, classified as a CS device, will report an alarm at 90°C.

    Operation:

    The 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 55°C. A high temperature CS heat detector, 55000-401, which can be installed in a typical ambient temperature of 55°C is available. This device will give 55 counts at 90°C.

    Application:

    The 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.
