G Series
Carbon Monoxide Transmitter
and Fan Controller
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.
NOTICE
Audible Alarm: An 85 dB alarm sounds if the CO level rises above 100 ppm for 30 minutes.

Installation
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 qualified service personnel. Install the G Series
sensor centrally in the parking structure, near the main traffic 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 floor.
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 flow patterns. Wide open areas where the air is well mixed may
require multiple sensors.

Service
TM
For any service or installation, consult qualified service personnel. To ensure continued reliable operation, replace the sensor
module every five 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 firmly 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 field calibration is required or possible. Verify proper operation by observing the LED
indicators.
Troubleshooting
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.
Z202025-0R

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.
