Addressable 4 wire Addressable CO Detector with Relay

Addressable CO Detector DHl-HY-AF640R, compatible with Dahuaaddressable fire alarm control panels, integrates CO detection intothe system. This significantly enhances system detection capabilities,enabling adaptation to diverse environmental requirements.CO detectors are safety devices for continuous monitoring of ambientCO concentrations. Upon detecting leaks exceeding preset thresholds,they trigger alarms and linkage the fire device through fire alarmsystem-to prevent explosions and protect personnel/property.
