Wiring the Outdoor Air CO2 Sensor

A dedicated power supply is required for this sensor. A two-wire cable is required to wire the dedicated power supply for the sensor. The two wires should be connected to the power supply and terminals 1 and 2.

To connect the sensor to the control, identify the positive (4 to 20 mA) and ground (SIG COM) terminals on the OAQ sensor. (See Fig. 52.) Connect the 4 to 20 mA terminal to RTU-MP J4-5. Connect the SIG COM terminal to RTU-MP J4-6. (See Fig. 55.)

(33ZCSENCO2) Connections

On 580J units equipped with factory-installed Smoke Detector(s), the smoke detector controller implements the unit shutdown through its NC contact set connected to the unit’s LCTB input. The FSD function is initiated via the smoke detector’s Alarm NO contact set. The RTU-MP controller communicates the smoke detector’s tripped status to the BAS building control. See Fig. 26 for unit smoke detector wiring.

The Fire Shutdown Switch configuration, MENU→Config→Inputs→input 5, identifies the normally open status of this input when there is no fire alarm.

Alarm state is reset when the smoke detector alarm condition is cleared and reset at the smoke detector in the unit.

Connecting Discrete Inputs

Filter Status

The filter status accessory is a field-installed accessory. This accessory detects plugged filters. When installing this accessory, the unit must be configured for filter status by setting MENU→Config→Inputs→input 3, 5, 8, or 9 to Filter Status and normally open (N/O) or normally closed (N/C). Input 8 or 9 is recommended for easy of installation. Refer to Fig. 42 and 43 for wire terminations at J5.

Fan Status

The fan status accessory is a field-installed accessory. This accessory detects when the indoor fan is blowing air. When installing this accessory, the unit must be

configured for fan status by setting MENU→Config→Inputs→input 3, 5, 8, or 9 to Fan Status and normally open (N/O) or normally closed (N/C). Input 8 or 9 is recommended for easy of installation. Refer to Fig. 42 and 43 for wire terminations at J5.
