Solid state technology – Cost-effective, reliable ASHRAE compliance

Haloguard

Single-Sensor CMOS monitoring
Four alarm relays are standard. Analog outputs are available to interface with building management systems or other remote devices.

Haloguard II

Multi-sensor multigas plus oxygen CMOS monitoring
Multiplex up to 6 sensors of any gas type (CFC, HCFC, HFC, Ammonia or Oxygen). Dry contact relays are activated when any sensor reaches an alarm condition. Analog output for up to 4 sensors.
