4To 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.

1Use 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.
