The HALOGUARD® II/IR combines microprocessor based controller with highly selective and sensitive remote photoacoustic infrared modules to provide the most advanced system for detecting the presence of halocarbons.
 
The multichannel controller monitors IR modules or 02 sensors in up to six separate locations, then provides both local and remote notification when gas concentration reaches preset alarm levels.
 
Alarm relays and analogue outputs are built in to activate remote devices or to interface with an energy management(EMS) or building automation (BMS) system.
 
  • Simple installation with easy field calibration
  • Easy expansion as requirements change
  • Up to six IR modules or oxygen sensors reporting to one central controller
  • Up to 1000 ft. transmission distance for each IR module
  • Up to 300 ft. transmission for 02 sensors
  • LCD shows PPM concentration, Alarm, Test, Reset, Sensor Fault Diagnostics, and Low Battery
  • Three Flashing Alarm LEDs
  • Sensor Fault LED
  • Relays for Hi & Low Alarm, Fault, and Off-scale conditions can activate ventilation, dialer or remote notification.
  • Analog outputs for BAS/EMS interface or data logging
  • Hi/Low independent, user adjustable alarm levels for each sensor
  • Off-scale alarm
  • Adjustable sensor scan rate
  • Self-diagnostics for each IR module
  • Built-in alarm Reset and Test push buttons
  • Rugged Plastic enclosure
  • Long-life, maintenance-free electrochemical oxygen sensors
  • Dependable, all solid-state microprocessor Electronics
