Connector
To connect an output device, repeat the previous steps but this time connect to
4
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.
Use wires of the correct gauge to connect either of the signal output pin pairs (1-
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.
