There is also the possibility of periodically monitoring the status of the

trigger object, for situations where this object is periodically received from the

bus. This will let Z41 Pro automatically assume the alarm situation if the “no

alarm” value does not get sent through the trigger object after a certain time,

for example upon failures of the transmitter. The maximum time window can

be defined by parameter.

Consequently, alarm boxes permit configuring the following parameters:

 Trigger: defines the value that will trigger the alarm (“0” or “1”; it is “1” by

default), i.e., the value that, when received through [Pn][Bi] Alarm Trigger,

should be interpreted by Z41 Pro as an alarm situation. Implicitly, this

parameter also defines the inverse “no alarm” value.

 Periodic Monitoring: activates (“Yes”) or deactivates (“No”, default option)

periodic monitoring of the alarm trigger object.

 Cycle Time (x 1min.): in case of having selected “Yes” under the above

parameter, sets the maximum accepted time space without receiving the

“no alarm” value before Z41 Pro adopts the alarm situation.
