Series 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 than 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.
