1
Use a connector to connect wires of the correct gauge to the sensor’s signal output pins. See
Chapter 46 on page 333 for the wire specifications. 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.

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.
1
Use wires of the correct gauge to connect either of the signal output pin pairs (1-normal close, 2-
common) or (2-common, 3-normal open) on the Signal connector to the input signal pin pairs of
an Signal connector on another ZyXEL Switch.
