connector--(4,5) (6,7) (8,9) (10,11). The pin numbers run from the right side of the connector to
the left.
Connect each of the sensor's two signal output wires to the Signal connector by depressing
2a
the spring clip corresponding to the pin you are connecting to.
Insert the wire and release the spring clip.

To connect an output devicel, repeat the previous steps but this time connect to either pins (1,2) or
4
(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.
Use wires of the correct gauge to connect either of the signal output pin pairs (1-normal close, 2-
1
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.
