NOTICE
• This product is not intended for life or safety applications.
• Do not install this product in hazardous or classied locations.
• Read and understand the instructions before installing
this product.
• Turn off all power supplying equipment before working on it.
• The installer is responsible for conformance to all applicable codes.
No responsibility is assumed byVeris Industries for any consequences arising out of the
use of this material.
PRODUCT IDENTIFICATION
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 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 in the Wiring section. 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. A minimum of one sensor for 5000 sq. ft. is recommended. Wide open areas where
the air is well mixed may require multiple sensors.

G SERIES INSTALLATION GUIDE
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.

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.
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.
SERVICE
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.
