Relay output
settings
The switching conditions for the relay output can be configured. The
function of an open switching relay (normally closed contact) or a
closed switching relay (normally open contact) can be specified.
It is also possible to specify whether the output should operate as a
bistable or as a monostable. In bistable operation, the activated
state of the relay remains as switched. In monostable operation, the
time can be selected after which the relay is to revert to its steady
state.
Various events can be selected to automatically activate the output.
In this way, for example, it is possible to switch on a floodlight when
a motion alarm has been detected and to switch the light off again
at the end of the alarm.
Idle state:
Select Open if the relay is to operate as a normally open contact or
Closed if it is to operate as a normally closed contact.
Operating mode:
Select the operating mode for the relay.
If, for example, a lamp is switched on by an alarm and is to remain
on when the alarm has ended, select Bistable. If an acoustic signal
activated by an alarm is to remain on for a period of, for example,
10 sec, select Monostable 10 s.
