FB_BA_SmokeDetector_01

The template is used to display faults and warnings of a duct smoke detector.

The binary output object RstHw can be used to reset these messages by remote release.

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

Outputs

Name	Type	Description
bSmokeAlarm	BOOL	Current value of the binary input object SmokeAlarm.
bSystemFailure	BOOL	Current value of the binary input object SystemFailure.
bContamination	BOOL	Current value of the binary input object Contamination.
bAirFlow	BOOL	Current value of the binary input object AirFlow.

Inputs CONSTANT

Name	Type	Description
SmokeAlarm	FB_BA_BI_Raw	Binary input object is used to process a smoke alarm.
SystemFailure	FB_BA_BI_Raw	Binary input object is used to process a system fault of the duct smoke detector.
Contamination	FB_BA_BI_Raw	Binary input object is used to process a pollution of the duct smoke detector.
AirFlow	FB_BA_BI_Raw	Binary input object is used to process insufficient air flow.
RstHw	FB_BA_BO_Raw	Binary output object which triggers a remote release on the smoke detector.
RstRm	FB_BA_BV_Op	The binary value object RstRm triggers a remote release on the smoke detector from the management level. The RstRm object is initialized as a button object by the additional parameter eToggleMode.

Variables

Name	Type	Description
tpResetHw	TP	The timing element extends the acknowledgement pulse for interfacing relay circuits (e.g. frost protection relay).
