Addressable 4 wire Natural Gas LPG Detector with Relay

Addressable Gas Detector DHI-HY-AA340R is a safety devicemonitoring ambient methane (CH4) or propane (C3Ha) concentration(mutually exclusive configuration). Triggers alarms upon reachingpreset thresholds and initiates fire suppression systems via integratedcontrol loops to mitigate explosion risks, ensuring personnel safety andproperty protection.Gas detectors are safety devices for continuous monitoring ofambient Natural Gas or LPG concentrations. Upon detecting leaksexceeding preset thresholds, they trigger alarms and linkage the firedevice through fire alarm system-to prevent explosions and protectpersonnel/property.
