Product Description
This document describes the hardware installation procedures for the GS-2CDD02K Series duct carbon dioxide gas detectors.
The GS-2CDD02K CO
2
transmitter uses Infrared Technology to monitor CO
2
levels up to 2000 ppm (adjustable to 10,000 ppm) and
outputs a linear 4-20 mA or 0-5/0-10 Vdc signal. Options include a control relay and a resistive temperature sensor. Features include
a back-lit LCD and a user menu for easy installation.
General Installation Requirements
For proper installation and subsequent operation of each device, pay special attention to the following recommendations:
- Upon unpacking the product, inspect the contents of the carton for shipping damages. Do not install damaged device.
- Avoid areas where corroding, deteriorating or explosive vapors, fumes or gases may be present.
- Ensure that all equipment is installed according to local, regional, and national regulations.
Personal injury or loss of life may occur if you do not follow a procedure as specified.
Equipment damage or loss of data may occur if you do not follow a procedure as specified.
Do not use in an explosive or hazardous environment, with combustible or flammable gases, as a safety or emergency
stop device or in any other application where failure of the product could result in personal injury.
Take reasonable precautions to prevent electrostatic discharges to the controller when installing, servicing or operating
the controller. Discharge accumulated static electricity by touching one’s hand to a well-grounded object before working
NOTE: This CO
2
sensor incorporates a Self Calibration feature to correct CO
2
sensor drift. This feature is recommended for
applications where the CO
2
will be exposed to fresh air (400 ppm) at least one hour per day. If the monitored space is occupied 24
hours or consistently maintains higher or lower levels of CO
2
, it is recommended that this feature be turned off, but yearly calibration
will be required. If the self calibration is disabled at installation time without allowing for 7 day auto calibration cycle, then a manual
calibration should be performed to ensure accuracy of the device.
