Apollo Series 65A 170°F Heat Detector with Flashing LED (Part No. 55000-142USA)

The Apollo Series 65A 170°F Heat Detector with Flashing LED (55000-142USA) 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 55000-142USA 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 and an integrated flashing LED that provides clear visual indication of device status. An optional magnet-operated test switch is also available to simplify routine testing and maintenance.
