Refrigerant sensors may also be paired with any toxic or combustible gases, such as CO or Methane. The analog output model features 2 outputs that support daisy chain wiring - multiple sensors may be used in a parallel sequence (0-10V) for cost effective coverage of large areas. The unit can also act as a stand alone controller, utilizing the relay for exhaust fan operation or the output for direct control of a VFD. The BACnet/Modbus model supports BACnet MS/TP & Modbus network communication in one unit. Standard features include network auto- configuration, programmable fan and alarm relays, LED indicators, integrated display and audible alarm.

Dedicated transformer is recommended. No mains circuit connection allowed. In addition, it is required to use an isolated power supply that is certified by a national or international standard (i.e. UL). Use of a Class 2 LPS power supply or greater is required. (2) R134A sensor is factory calibrated to R134A gas but may be used as a general purpose refrigerant sensor. Sensitivity to some other gases can be found in the installation manual. Actual response may vary depending on installation. For more accurate response to a specific gas, a unit may be field calibrated. (3) These gases my be detected by the sensor but sensitivity curves are not available at this time. Scan here to see refrigerant cross- sensitivities *Refrigerant gas sensors may be paired with all other TG gas offerings, except Methane, Propane, and Hydrogen.
