Dahua Addressable Heat Detector (RI Support), DHI-HY-2311B (MOQ-2Pcs)

Dahua Addressable Heat Detector (RI Support), DHI-HY-2311B is a 4W-B Addressable Heat Detector that Operates on a Polarity-free Two-wire power supply. It Primarily utilizes a thermal sensing Element to Detect Fires. During the initial stages of a Fire, a significant amount of Heat is Released, causing a Rapid increase in the Surrounding temperature. The Thermal element in the Detector undergoes a Physical change in response to Abnormal Temperature, temperature rate, and temperature differential, converting the temperature signal into an Electrical Signal to trigger an Alarm.
