Apollo XP95 55000-420APO Heat Detector (A2S)

The Apollo XP95 55000-420APO Heat Detector is an addressable Class A2S heat detector designed to provide reliable fire detection in environments where smoke detectors may be unsuitable due to normal levels of dust, smoke, fumes, or airborne contaminants. Using a thermistor-based sensing element, the detector continuously monitors the surrounding air temperature and generates an alarm when the temperature reaches approximately 55°C.

The 55000-420APO features a common profile with the XP95 optical smoke detector range, allowing a consistent appearance throughout an installation. However, it incorporates a low airflow resistance case manufactured from durable white polycarbonate, enabling heat to reach the sensing element quickly and efficiently.

Furthermore, the detector remains unaffected by wind and atmospheric pressure changes, ensuring dependable performance across a wide range of operating conditions. As a result, it is particularly well suited to applications where environmental conditions could lead to unwanted alarms from smoke detection devices.
