The Apollo 55000-145APO is a Series 65A conventional heat detector rated at 200°F, with a flashing LED. It monitors temperature using a dual thermistor network that gives a voltage output proportional to the external air temperature, and is part of Apollo's UL-listed Series 65A range.
Heat detectors suit applications where smoke detectors are unsuitable, such as environments that are dirty or smoky under normal conditions.
