To better understand this behaviour, please read the following application example:
Example:
Suppose that a cyclical monitoring time of 3 minutes is configured for the Alarm 1. The trigger
value is “1” and the reaction of the actuator when the alarm is activated is to raise the shutter and
when the alarm is deactivated, ACTinBOX MAX6 lowers the shutter. Figure that the shutter is
down. At this moment, a “1” is received through the communication object “[CX] Alarm 1”, so the
Alarm 1 will be activated, thus raising the shutter. While the alarm is not deactivated, any action
over the channel outputs will be ignored. After a while (t2), the alarm is deactivated (“[CX]
Alarm=0”), thus lowering the shutter. Before the cyclical monitoring period (3 minutes) ends, a
new alarm deactivation order arrives from the KNX bus, so this time starts counting again. After 3
minutes without any action performed over the alarm object, it is automatically activated, raising
the shutter. Like before, any action over the output will be ignored until the alarm is deactivated.
See figure 3.16.
