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
qualied service personnel The G Series sensor should be installed 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 
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.
