PRODUCT 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.
