Apollo XP95 55000-400APO Heat Detector (A2S)

Apollo XP95 Standard Temperature Heat Detector (55000-400APO)

The Apollo XP95 55000-400APO 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, steam, or airborne contaminants. Using a single thermistor sensing element, the detector continuously monitors the surrounding air temperature and generates an alarm when the temperature reaches approximately 55°C.

As part of the proven XP95 range, the 55000-400APO combines dependable heat detection with the benefits of Apollo’s digital addressable technology. Furthermore, its robust design provides high immunity to electrical interference, making it particularly suitable for medium-to-large fire detection systems where reliable communication and life safety are critical.

The detector features a low airflow resistance housing manufactured from self-extinguishing white polycarbonate. As a result, heat can reach the sensing element quickly and efficiently, ensuring accurate temperature monitoring while remaining unaffected by wind or atmospheric pressure changes.
