Apollo Series 65A 170°F Heat Detector (Part No. 55000-143USA)

Please note: this product is now obsolete

The Apollo Series 65A 170°F Heat Detector (55000-143USA) 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 55000-143USA 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 is available with optional flashing LED and magnet-operated test switch functionality to simplify routine testing and maintenance.
