Detect Methane/Propane leaks and monitor for elevated CO levels, all in one unit. 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, APPLICATIONS ▪ Boiler rooms ▪ Commercial kitchens ▪ Battery Rooms ▪ Compressed Gas storage ▪ Residential and commercial heating and water heating ▪ Vehicle bays and garages for natural gas (LNG) or petroleum gas (LPG) vehicles ▪ Waste facilities ▪ Monitor multiple combustible gases with one mounted unit ▪ Alert occupants of elevated gas levels ▪ Directly control exhaust fans Cost-effective dual gas sensing and control ▪ Integrated display, LED indicators, audible alarm ▪ Order as individual CO, NO2, Propane, Methane, Hydrogen, Oxygen, or Hydrogen Sulfide sensor, or specify any two sensing elements in one enclosure Flexibility of analog output model ▪ Menu selectable 0-5/10V, 1-5V and 4-20mA outputs (0- 10V default) ▪ Dual outputs support daisy chain wiring to cost- effectively sense and control large areas Versatility with BACnet/Modbus model ▪ Supports BACnet MS/TP and Modbus RTU networks ▪ Auto-configuration detects network baud rate, serial format, protocol type and self-addresses High reliability reduces call backs ▪ Temperature compensated elements for maximum accuracy ▪ UL2034 recognized electrochemical CO sensing element ▪ Warning indicators alert occupants when element’s lifecycle is near end for replacement ▪ 7-year limited warranty on electronics; 2-year on elements Easy to install ▪ Through the back wiring ▪ Test mode speeds up field commissioning for verifying warning indicators and relay functions ▪ Push buttons and LCD to navigate 7 year limited warranty PROUDLY MADE IN USA NEW !Higher Reliability, Faster Installation, Superior Accuracy | Sense the difference | 89 AIR QUALITY AIR QUALITY Toxic Gas Series ORDERING Replacement Elements TGS-CO-UL = Carbon Monoxide TGS-NO2-UL = Nitrogen Dioxide TGS-CH4-UL = Methane TGS-C3H8-UL = Propane TGS-O2-UL = Oxygen TGS-H2-UL = Hydrogen TGS-S-UL = Hydrogen Sulfide SPECIFICATIONS Power Supply15-30 VDC/24VAC (1) , 4 W max, 160 mA max.

Dedicated trans- former is recommended. No mains circuit connection allowed. In addition, it is required to use an isolated power supply that is certi- fied by a national or international standard (i.e. UL). Use of a Class 2 LPS power supply or greater is required.
