Apollo XP95 55000-885APO Multisensor Detector (Optical/Heat)

Apollo Multisensor Detector (55000-885APO)

The Apollo XP95 55000-885APO Multisensor Detector combines an optical smoke sensor with a thermistor temperature sensor to deliver enhanced fire detection performance across a wide range of fire types. By continuously monitoring both smoke levels and rapid temperature changes, the detector provides a balanced response to both smouldering and fast-flaming fires, making it suitable for most general applications.

Built on the proven XP95 optical detector platform, the 55000-885APO features modified optical mouldings and a redesigned housing to accommodate the integrated temperature sensor. The optical and thermal sensing elements operate independently, allowing the detector’s onboard microcontroller to analyse and combine data from both sources to produce a single analogue value for the control panel.

Furthermore, the detector processes only rate-of-rise temperature information alongside the optical smoke signal. As a result, it responds to sudden increases in temperature while remaining unaffected by gradual temperature rises, even when high ambient temperatures are reached. When a significant and sustained temperature increase occurs for approximately 20 seconds, the detector can generate an alarm even in the absence of smoke.

In addition, the 55000-885APO incorporates drift compensation algorithms that automatically compensate for contamination within the sensing chamber over time. This helps maintain consistent performance throughout the detector’s operational life.
