Apollo Series 65A 135°F Heat Detector with Flashing LED and Magnetic Test Switch (Part No. 55000-138APO)

The Apollo Series 65A 135°F Heat Detector with Flashing LED and Magnetic Test Switch (55000-138APO) provides reliable heat detection in environments where smoke detectors may not be suitable. Using a dual thermistor network, it monitors the surrounding air temperature and generates a voltage output proportional to temperature changes, enabling accurate and dependable heat detection.

The 55000-138APO performs reliably in environments where dust, smoke, steam, or airborne contaminants are present during normal operation. By responding to heat rather than smoke particles, it helps reduce unwanted alarms while maintaining dependable fire detection.

Designed as part of the Apollo Series 65A range, the detector features a wide operating voltage range, an integrated flashing LED for clear visual indication, and a built-in magnetic test switch that simplifies routine testing and maintenance.
