FB_BA_BuildingAlarms

This template summarizes building-specific safety criteria and makes them available in a globally declared structure stBuildingAlarms (see global variable list Site).

The criteria in detail are:

1. Fire alarm (FireAlert): this alarm is read in directly via a binary input object.
2. Burglar alarm (Bgly/Burglary): this alarm is read in directly via a binary input object.
3. Central switch-off (CentSwiOff), actually no alarm. This input object makes it possible, for example, to reset manual flags building-wide or to switch off lights at this central point.
4. Forced ventilation (ForcedVenilation): in this template on reserve, to trigger forced ventilation.
5. Smoke extraction (SmokeExtraction): in this template on reserve, to trigger a smoke extraction operation.

The initialization of the template takes place within the method FB_Init.
