FB_BA_FireAlarmSystem

This template receives the fire alarm as an input via an FB_BA_SensorBinary function block and transfers it as Site.stBuildingAlarms.bFireAlert to the local variable list Site.

The alarms are made available to other controllers in the FB_BA_AdsComServer_Basic template.

The FireDetector01 sub-template represents a fire detector or a fire alarm system (aggregate level). If there are several fire detectors/fire alarm systems, the FB_BA_FireAlarmSystem template must be extended.

The recording of the signal is defined in FB_Init as a quiescent current principle (FireDetector01.Input.ePolarity := E_BA_Polarity.eReverse).

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