Chapter 3 Hardware Overview 3.1.7.1 Connect a Sensor to the Signal Slot This section shows you how to connect an external sensor device to the Switch. 1 Use a connector to connect wires of the correct gauge to the sensor's signal output pins. Be sure to check the sensor's documentation to identify its two signal output pins. 2 Connect these two wires to any one of the following pairs of signal input pins on the Switch's Signal connector--(4,5) (6,7) (8,9) (10,11). The pin numbers run from the right side of the connector to the left. 2a Connect each of the sensor's two signal output wires to the Signal connector by depressing the spring clip corresponding to the pin you are connecting to. 2b Insert the wire and release the spring clip. 2c Repeat the process for the sensor's other signal output wire. A total of four sensors may be connected to the Signal connector in this way using the remaining signal input pins. 3 Insert the alarm connector into the Signal slot. Figure 17 Connecting a Sensor to the Signal Slot 4 To connect an output devicel, repeat the previous steps but this time connect to either pins (1,2) or (2,3) on the Signal connector. You can also daisy-chain the external alarm to another ZyXEL Switch which supports the external alarm feature. If daisy-chaining to a ZyXEL switch that is a different model, check your switch's documentation for the correct pin assignments. MES-3528 User's Guide 37

3.1.7.1
Connect a Sensor to the Signal Slot
This section shows you how to connect an external sensor device to the Switch.
1
Use a connector to connect wires of the correct gauge to the sensor’s signal
output pins. Be sure to check the sensor’s documentation to identify its two signal
output pins.
2
Connect these two wires to any one of the following pairs of signal input pins on
the Switch’s
Signal
connector--(4,5) (6,7) (8,9) (10,11). The pin numbers run
from the right side of the connector to the left.
2a
Connect each of the sensor’s two signal output wires to the
Signal
connector
by depressing the spring clip corresponding to the pin you are connecting to.
2b
Insert the wire and release the spring clip.
2c
Repeat the process for the sensor’s other signal output wire. A total of four
sensors may be connected to the
Signal
connector in this way using the
remaining signal input pins.
3
Insert the alarm connector into the
Signal
slot.
Figure 17
Connecting a Sensor to the
Signal
Slot
4
To connect an output devicel, repeat the previous steps but this time connect to
either pins (1,2) or (2,3) on the
Signal
connector.
You can also daisy-chain the external alarm to another ZyXEL Switch which
supports the external alarm feature. If daisy-chaining to a ZyXEL switch that is a
different model, check your switch’s documentation for the correct pin
assignments.
