Product Information

Unlike smoke detectors that detect the presence of smoke particles, heat detectors only react to changes in temperature.

The EV-H-A1R is a Thermistor based Heat Detector, which use electronic components that change their resistance when heated; this change is detected by circuitry within the detector.
