Choose from14 gases including CO/NO2, combustibles, and refrigerants Choose Modbus RTU and BACnet MS/TP protocols or Analog output Field replaceable factory-calibrated sensing elements Integrated LED indicator, audible alarm, and two configurable relay outputs
Single or dual sensors on each unit. (refrigerant sensors may only be single element units)
Choose from up to two gases, supporting CO, CO2, NO2, CH4, C3H8, H2, O2. H2S, NH3, and refrigerants for the ultimate in versatility
Field-replaceable, digital factory-calibrated elements automatically adjust set-point and alarm thresholds for easy installation
Dual analog outputs support daisy chain wiring to cost-effectively sense and control large areas
Standard setpoint relay for direct fan control or daisy chain for central alarm activation eliminates need for costly controllers
Rugged, IP54, tamper-proof enclosure is unobtrusive, and tamper resistant for both surface or recessed j-box
7-year limited warranty on electronics; 2-years on sensor elements
Calibration certificate included with every sensing element to facilitate fast commissioning
UL listing for element only, UL2034 recognized electrochemical CO sensing element
Senva UL Listed TG Series sensors can be ordered as individual CO or NO2 sensors or as a combination CO/NO2 sensor in a shared enclosure.
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, a programmable fan relay, LED indicators, integrated display and audible alarm.

(1) One side of transformer secondary is connected to signal common. 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)Extreme temperatures may affect accuracy when using 4-20mA outputs. (3) Carbon Monoxide full scale is 1000ppm. (4) Nitrogen Dioxide full scale is 30ppm. (5) Accuracy of CO2 reading may be reduced at temperatures below 14ºF (-10ºC). (6) Refrigerant sensor may only be ordered as a single element sensor. It cannot be combined with other sensors. (7)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. (8) These gases my be detected by the sensor but sensitivity curves are not available at this time. (9) Refrigerant sensors have been tested to perform at this altitude. To maintain accuracy spec, a field calibration is recommended.
