Heat Detector
Part No: F15-81200

Unlike smoke detectors that detect the presence of smoke particles, heat detectors only react to changes in temperature. The ST-H-AS is a Thermistor based Heat Detector, which uses electronic components that change their resistance when heated; this change is detected by circuitry within the detector.
