2.4.1.2
ALARMS
The Alarms function allows changing the state of the output on the reception of an alarm
trigger from the KNX bus. It is possible to configure the state the output will be switched
to, both on the alarm
activation
and on the alarm
deactivation
.
Cyclically monitoring
the alarm trigger is also possible by defining a certain time period.
The actuator will check that the alarm or no-alarm state is received at least once before
the period expires (note: this check doesn’t take place unless the object has been
received at least once). In case the object stops being refreshed (i.e., the actuator does
not receive an updated value anymore), the alarm action will be performed as well, for
safety reasons.
Regarding the deactivation of the alarm, it is also possible to configure a simple
deactivation or an
acknowledgement-demanding
deactivation.
The first case triggers the deactivation action as soon as the alarm object
recovers its normal value.
The second one, on the other hand, requires that an external
acknowledgement (through another object) is received after the alarm object
has recovered its normal value.
Notes
:
Alarms always prevail
over other functions (e.g.: lock orders during the alarm
state will be ignored; alarm orders during the lock state will not).
Alarm
has priority over Alarm 2.
If a channel is in alarm 2 and alarm 1 is
activated, the alarm 1 action will be executed until the alarm 1 is deactivated,
resuming the alarm 2 status (but without executing the alarm 2 action again).
