4.3.3 Connecting a Monitoring Cable to an Independent
Deployment AI/DI Unit
Prerequisites
A network cable used for monitoring is prepared.
Procedure
Step 1 Connect one end of the network cable to the COM_IN port on the independent deployment
AI/DI unit.
Step 2 Connect the other end of the network cable to the COM port with 12 V power supply on the
collector, namely COM4 or COM5 port.
Step 3 (Optional) If multiple independent deployment AI/DI units need to be cascaded, connect the
COM_IN port on one independent deployment AI/DI unit to the COM_OUT port on another
independent deployment AI/DI unit.

Port Description
Provide 12 V DC outputs for sensors and are compatible with 4 mA to
20 mA current signals, signals from current-based smoke sensors and
water sensors, dry contact signals, and NTC signals.
Pin definition:

3: 12 V DC, 54 mA
 6: D-

7: D+
 8: GND
Do not connect an active sensor to an AI/DI port. Otherwise, the port will be invalid.

 Sensors including 4 mA to 20 mA sensors, door status sensors, water sensors, and smoke sensors
provide data for the ports.
 The power supply of each AI/DI port can be separately controlled. Each port provides a maximum of
14.6 V, 54 mA output power.
A maximum of two independent deployment AI/DI units can be cascaded to the COM4 or COM5

port on the ECC500.
 When the number of AI/DI ports for the ECC500 collector is insufficient, collect the device to the
independent deployment AI/DI unit.
