5. Apply power to the unit. A green LED on the circuit board indicates power is applied.
0 = Station Only 1 = 1 Sensor 2 = 2 Sensors 3 = 3 Sensors 4 = 4 Sensors
Note: Coverage is NOT dependant on the sensor. Coverage is a function of the building structure and air flow patterns. A minimum of one sensor for 5000 sq. ft. is recommended. Wide open areas where the air is well mixed may require a few sensors.

OPERATION The GMxA Series monitoring station accepts digital inputs from up to four G Series carbon monoxide sensors. It provides alarm status indication for each input and a normally open Form C (SPDT) fan actuation relay controlling a normally closed fan contactor. If any of the four sensors detect CO levels above 25 ppm, or if a fault is detected, the corresponding alarm status indicator light turns on and the fan relay will activate the fan.

Connect G Series sensors to input terminals as indicated. To ensure proper operation, all unused inputs must be jumpered from (V+) to (IN) as shown in the wiring diagram. To provide fail-safe operation, the normally open fan relay contacts must be used with a normally closed motor starter or contactor.

3. Connect only Veris Industries, G Series carbon monoxide sensors to the GMxA monitoring station. 4. Connect only 24VAC/24VDC power to the two-position terminal block as shown in the wiring diagram. Connect a ground wire to the metal case at a mountinig screw or metal conduit fitting.
PRODUCT IDENTIFICATION GM
2. Select a location for the sensor in a secure area where it will be accessible only to qualified service personnel. The GMxA Series monitoring station should be installed 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.
