55000-400APO Apollo XP95 Heat Detector (A2S)

Engineering the future of fire safety has been the primary goal of Apollo Fire Alarms. The cornerstone of their success lies in the development of revolutionary products such as the Apollo XP95 Heat Detector.

Key Features of the XP95 Heat Detector (A2S)

  • Thermistor Monitoring: Utilizing a single thermistor, the Apollo XP95 heat detector monitors temperature with precision. It provides a count output proportional to the external air temperature, reporting an alarm at 55 °C.

  • Reliability: This detector is designed to perform reliably in areas with a wide temperature range (-20 °C to +70 °C), making it an ideal choice for environments that are dirty or smoky under normal conditions.

  • Resilience: The Apollo XP95 heat detector is unaffected by wind and atmospheric pressure. Its resilience is a testament to its advanced design and meticulous engineering.
