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 b uilding structure and air ow patterns. A minim um of one sensor for 5000 sq. ft. is recommended. Wide open areas whe re the air is well mixed may require mu ltiple 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

Output is inaccurate or unstable • Allow 96 hours for sensor to burn in and stabilize.

• Verify span jumper is set to desired scale.

• For voltage units, verify jumper is set to desired

voltage output scale.

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.
