Note
1. It is recommended to use the auxiliary sensors shown in Figure 3-5. If you want to connect other types of sensors, make the
connection cables according to the port pin definition in Figure 3-4 and then connect them.
2. Both vibration sensor and water sensor use D3 channel. If the vibration sensor is selected, it cannot share the same digital
sensor port with the water sensor.
3. The line sequence (see Figure 3-4 for detailed definition) of the DI1, DI2 and DI3 ports is fixed. The types of the sensors
connected to a port cannot be the same.
If the digital sensor (with a connection cable in factory) recommended by Emerson is connected, insert the RJ45
connector of the connection cable into the DI1, DI2 or DI3 port.
The recommended sensors are shown in Figure 3-5.

Connecting multiple signals of RJ45 ports
DI1, DI2 and DI3 ports can be connected with multiple signals simultaneously.
When a port is connected to multiple signals, RJ45 three-way connectors (optional) are required for transferring
according to the signal amount. Use standard straight network cables to cascade-connect the signals in daisy chain
mode and then connect them with the corresponding port. Figure 3-6 indicates the connection method that DI1 port is
connected with infrared sensor, door magnet sensor and smoke sensor.

Figure 3-6 Connecting multiple sensors
When a port is connected with multiple signals simultaneously, you must note that the line sequence conflict of the
signals cannot occur. For example, the DI1 port can be connected with four sensors simultaneously. The
recommended sensors include smoke sensor, door magnet sensor, water sensor and infrared sensor. If the DI1 port
is connected with vibration sensor and water sensor simultaneously, signal conflict will occur, resulting in signal
acquisition failure, because both sensors use the DI3 channel.
3.2.3 Connecting IRM Sensor Port
The IRM sensor port (silkscreen: TH_BUS) is used to connect the IRM series temperature sensor and temperature &
humidity sensor.
Note
The address range of the IRM series temperature sensor and temperature & humidity sensor is 10, 11, 12, 13, 20, 21, 22 and 23;
besides the above addresses, the address range of the IRM series temperature sensor also includes 30, 31, 32, 33, 40, 41, 42 and
