ProDuct iDentification
quick install
Lock out all power supplies prior to installation
Select a location for the sensor in a secure area where it will be accessible only to
qualied service personnel The G Series sensor should be installed centrally in the
parking structure near the main trac paths but away from outside air vents and
excessive drafts Mount the unit securely to a wall or column at a height of about
ft m from the oor
Connect wiring as shown in the Wiring Diagram
Apply power to the unit A green LED on the circuit board indicates proper
operation of the power supply
Note: Coverage is NOT dependant on the sensor Coverage is a function of the building structure
and air ow patterns A minimum of one sensor for sq ft is recommended Wide open areas
where the air is well mixed may require a few sensors

oPeration
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. The G Series
devices are equipped with a relay contact that closes when CO level is below 25ppm
and opens when the CO level is above 25ppm (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: 85dB alarm sounds if CO level rises above 100ppm for 30 minutes.

service
For any service or installation consult qualied service personnel To assure
continued reliable operation the sensor module should be replaced every ve years
with a Veris Industries CO sensor replacement module
Replacement instructions:
Disconnect power from the unit
Carefully remove the old sensor module
Install the new module rmly into the socket
Reconnect power to the unit
The replacement sensor requires hours after initial power application to
The sensor module is factory calibrated No eld calibration is required or possible
Verify proper operation by observing LED indicators
