Tyrol Warning and Alerting System

The system consists of a radio alerting network in the form of around 50 high-altitude alarm transmitters that supply around 110 low-altitude alarm transmitters. Alarms are distributed to all alarm transmitters in the radio network via a feeder network (1m band) at the 50 high-altitude transmitters and to the low-altitude alarm transmitters via a distribution network (2m band) regardless of the POCSAG frequency. The modulation method used is 4-level FSK with a rate of 9600Bd.

After the alarm has been transmitted throughout the entire infrastructure via the feeder and distribution network to all alarm repeater, the POCSAG transmission is sent to all repeaters to alert pagers and siren terminals. The alarm packages are distributed redundantly to all repeater locations and the intelligent siren terminals via the BOS digital radio network of the province of Tyrol. In order to achieve the required triggering times and throughput rates, a special synchronization procedure is used that allows simultaneous POCSAG transmission during alerting by the alarm repeater.

The nationwide alerting of pagers and sirens is carried out centrally by the Integrated Control Centre Tyrol. At the same time, alarms are triggered by the district command centers as a redundancy level and extension level to the Tyrol Control Center in the event of major incidents. Further alarm triggering, especially for civil protection and disaster control, is achieved via interfaces to the state and federal warning center.

The system status and thus also the individual status of all alarm repeater in the network is queried cyclically (cycle time configurable) via the feeder/distribution network or via TETRA and logged and stored on the alarm server.
