Apollo Series 65 A1R Heat Detector with Flashing LED and Magnetic Test Switch (Part No. 55000-120APO)

The Apollo Series 65 A1R Heat Detector with Flashing LED and Magnetic Test Switch (55000-120APO) provides reliable heat detection in environments where smoke detectors may not be suitable. Housed in a self-extinguishing white polycarbonate case, it is designed to deliver dependable performance in commercial, residential, and light industrial applications.

The 55000-120APO performs effectively in environments where dust, smoke, steam, or airborne contaminants are present during normal operation. As an A1R rate-of-rise heat detector, it responds to both a fixed temperature threshold and rapid increases in temperature, helping provide early warning of developing fires while reducing unwanted alarms.

Designed as part of the Apollo Series 65 range, the detector incorporates nickel-plated stainless steel wiper contacts that provide a secure connection to the mounting base. The integrated flashing LED provides clear visual indication of alarm status, while the built-in magnetic test switch simplifies routine testing and maintenance.
