Advanced Mode: Relay

You can configure the switching behavior of the relay outputs. For each relay, you can specify
an open switch relay (normally closed contact) or a closed switch relay (normally open
contact).
You can also specify whether an output should operate as a bistable or monostable relay. In
bistable mode, the triggered state of the relay is maintained. In monostable mode, you can set
the time after which the relay will return to the idle state.
You can select different events that automatically activate an output. It is possible, for
example, to turn on a floodlight by triggering a motion alarm and then turning the light off
again when the alarm has stopped.
Idle state
Select Open if you want the relay to operate as an NO contact, or select Closed if the relay is
to operate as an NC contact.
