Only when the alarm or warning threshold is detected number of times specified by the repeat parameter
such data is noted and reported. This is made to avoid triggering accidental alerts. Similarly, in order to
remove the alarm / warning status, the value of a source of the alert must not exceed the threshold for
the number of times specified in the repeat field. This applies to field Acquisition parameters area in
Configuration website tab. For example, an alarm will be reported at the Repeat parameter equal to 2
during the third threshold violation (1 occu 2 repetitions).

Method of operation
AVM GATEWAY is the coordinator of wireless sensor network. It is used for configuration or downloading
measurements and reports from all sensors. It also stores all data in non-volatile memory and presents
them to users. It has connectivity via Ethernet, Modbus and OPC protocol. The alarms and warnings are
reported through the GATEWAY device.
