According to the BACnet protocol documentation:

Defines a standardized object whose properties represent the externally visible characteristics of a binary lighting output and includes dedicated functionality specific to lighting control that would otherwise require explicit programming. This object is binary in nature and can be either in a logical on or off state. The object is commanded by writing to the Present_Value property. This property is commandable and uses a priority array to arbitrate between multiple writers to the binary lighting output.

Objects of type binaryLightingOutput have the following properties:

•ackedTransitions

•blinkWarnEnable

•commandTimeArray

•currentCommandPriority

•description

•egressActive

•egressTime

•elapsedActiveTime

•eventDetectionEnable
