Description

The GDT Series of gas monitoring sensors monitor levels of carbon monoxide (CO) and/or nitrogen dioxide (NO2) to provide an early warning of elevated concentrations.

The GDT is available as a standalone CO or NO2, as well as a CO/NO2 dual sensor device. The dual sensor device is available in 2 configurations: CO/NO2 housed one enclosure or as CO with remote NO2 sensor for mounting at a higher location.

The GDT gas sensors are encapsulated in field replaceable sensors pods that are located on the bottom of the enclosure. The pod design provides a greater area of gas sampling then that of devices that utilize a single vent hole. Replacement pods come pre-calibrated and ready for installation.

The GDT is available with either Analog, BACnet or Modbus outputs for communication with a building automation system. Standard features include LCD display for configuration and local display as well as status LED’s. Optional features include: 1 or 2 adjustable control/alarm relays, adjustable audible (buzzer) & visual (strobe) alarms as well as various temperature sensor.

The GDT is housed in an IP65 polycarbonate enclosure with a hinged and gasketed cover that provides ease of installation and access for set up and configuration.

 

Please specify in the Order comments field, whether you need Analog Output or DC Voltage Output options, Concealed or Visible LCD display.

For Relay, Audible/Visual Alarm, Temperature Sensor or BACnet MSTP/Modbus RTU options, please contact us.
