Room Carbon Dioxide Detectors

Product Description

The GS-CDR20K Series are room carbon dioxide gas detectors.

These devices provide precision measurement of CO

CDR20K series uses a highly accurate and reliable Non-dispersive

combined

linearization and temperature compensated circuitry in an attractive,

low profile enclosure for room applications to monitor room CO

levels.

A linear analog signal output of 4-20 mA, 0-5 or 0-10 Vdc is provided

for connection to a building automation system. Optional features such

as temperature sensor, setpoint adjustment, manual override and

adjustable relay output are available.

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 with the controller.

Mounting Instructions

The room type sensor installs directly on a standard electrical box and

should be mounted five feet from the floor of the area to be controlled.

Do not mount the sensor near doors, opening windows, supply air

diffusers or other known air disturbances. Avoid areas where the

detector is exposed to vibrations or rapid temperature changes.

The cover is hooked to the base at the top edge and must be removed

from the bottom edge first. Use a small screwdriver to carefully pry

each bottom corner if necessary. If a security screw is installed on the

bottom edge, then it may have to be loosened or removed also. Tip the

cover away from the base and set it aside.

The PCB must be removed from the base to access the mounting

holes. Follow usual anti-static procedures when handling the PCB and

be careful not to touch the sensors. The PCB is removed by pressing

the enclosure base to unsnap the latch near the bottom edge, then the

PCB can be lifted out of the base. Set the PCB aside until the base is

mounted on the wall.
