5.26 Relay Settings
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.
5.26.1 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.
5.26.2 Operating mode
Select an operating mode for the relay.
For example, if you want an alarm-activated lamp to stay on after the alarm ends, select
Bistable. If you wish an alarm-activated siren to sound for ten seconds, for example, select
10 s.
