About this product
The 8862-101-1150-707-9 Fire/Overheat Detector is a core sensing element. Designed to detect excessive temperatures in engine nacelles, APU compartments, and other high-heat zones, it uses thermally responsive elements that close an internal circuit when a preset temperature is reached.

PRODUCT DESCRIPTION

8862-101-1150-707-9

  • Precise Trip Temperature: Calibrated to activate at the specified overheat threshold (typically 200–300 °C), ensuring rapid and reliable fault detection.

  • Fast Response Time: Employs low-thermal-mass sensing elements for activation within seconds of temperature exceedance, minimising damage risk.

  • Redundant Sensor Elements: Dual-element design provides continued operation if one sensing element degrades, enhancing system integrity.

  • Rugged Construction: Housed in corrosion-resistant stainless steel with sealed internals to withstand vibration, moisture, and chemical exposure.


  • Monitoring engine nacelle bays for overheat conditions.

  • Protecting auxiliary power unit compartments against thermal faults.

  • Integrating into the wing and fuselage fire detection loops.

  • Safeguarding environmental control system bays in larger transports.


  • How does an overheat detector differ from a fire detector?

Overheat detectors respond solely to temperature rise, whereas fire detectors sense radiant energy or flame signatures.

  • Can the detector be reused after activation?

Yes, once cleaned and bench-tested to OEM tolerances, the unit can be returned to service under approved overhaul procedures.

  • Where in the fire-detection loop is this part installed?

It mounts in the loop at designated overheat sensing points, connected in series with other detectors and the fire-warning controller.
