Product Identification
Product Overview
The G Series carbon monoxide detectors measure CO levels and signal control systems to provide an inlet of fresh
air optimal for the space at a given time. G Series devices are equipped with a relay contact that closes when
the CO level is below 25 ppm and opens when the CO level is above 25 ppm (when used with a normally closed
contactor). Removal of the sensor, interruption of power, or cut wires cause the relay circuit to open and start the
fan. Minimum relay cycle time is 3 minutes to prevent fan short-cycling.
Audible Alarm: An 85 dB alarm sounds if the CO level rises above 100 ppm for 30 minutes.

Dimensions
1. Lock out all power supplies prior to installation.
2. Select a location for the sensor in a secure area where it will be accessible only to qualied service personnel. Install the G Series
sensor centrally in the parking structure, near the main trac paths, but away from outside air vents and excessive drafts.
Mount the unit securely to a wall or column at a height of about 5 ft. (1.52 m) from the oor.
3. Connect wiring as shown below. If using a voltage output model, use the output jumper to select 0-5 V or 0-10 V.

4. Apply power to the unit. A green LED on the circuit board indicates proper operation of the power supply.
Coverage is not dependent on the sensor. Coverage is a function of the building structure and air ow patterns. Wide open areas where the air is well mixed may
require multiple sensors.

Installation Guide
Air Quality
GSeries TM
For any service or installation, consult qualied service personnel. To ensure continued reliable operation, replace the sensor
module every ve years with a Veris Industries CO sensor replacement module (Veris part number AA09).
Replacement instructions:
1. Disconnect power from the unit.
2. Carefully remove the old sensor module.
3. Install the new module rmly into the socket.
4. Reconnect power to the unit.
5. The replacement sensor requires 96 hours to stabilize after initial power application.
The sensor module is factory calibrated. No eld calibration is required or possible. Verify proper operation by observing the LED
indicators.
Problem Solution
4-20 mA output does not function • Verify that the unit is a 4-20 model.
• Verify that the unit is wired for sourcing output.
Output is half or twice what is
expected
• Verify span jumper is set to desired scale.
• For voltage units, verify jumper is set to desired
voltage output scale.
Output is inaccurate or unstable • Allow 96 hours for sensor to burn in and stabilize.
