Haloguard II
Haloguard II 24-hour Multichannel, Multigas Detection and Notification Refrigerant Leak Detection
and Monitoring Systems
With dependable solid state electronics, HALOGUARD ® II is a cost effective, reliable way to detect the presence of halo-carbons, ammonia, and oxygen depletion. The multi-channel, multi-gas HALOGUARD ® II controller monitors sensors in up to six separate locations and provides both local and remote notification when gas concentration reaches an alarm level.
We’ve built in alarm relays and analog outputs to activate remote devices or to interface with a computer controlled energy management or building automation system.
