Haloguard III Photoacoustic Infrared, Multichannel, Multigas Detection and Notification Refrigerant Leak Detection and Monitoring Systems

The HALOGUARD ® III combines advanced microprocessor based digital signal processing and a wideband photoacoustic infrared cell to provide the newest most advanced system for continuous monitoring of all refrigerant gases.

The HALOGUARD ® III monitors single or multiple,local and remote locations and provides notification when gas concen- tration reaches preset alarm levels.Up to 24 different gases may be monitored simultaneously by adding optional channel scanners and remote IR modules.

Alarm relays and analog outputs are designed to activate remote devices or to interface with an energy management (EMS)or building automation (BAS)system.
