Profile_Name (Read-only)
The value of this property is “178-http://www.loytec.com/xsd/DALIOccupancy Sensor/v1”.
Debounce (Read/Write)
The value of this proprietary property (property ID 535) specifies the debouncing time in
seconds (see Section 8.2.7.1).
Unoccupied_Delay (Read/Write)
The value of this proprietary property (property ID 536) determines the delay in seconds
after which the state changes to unoccupied. The timer is armed each time the value
reported by the sensor changes from occupied to unoccupied. A value of 0 disables the
unoccupied delay.
Heartbeat (Read/Write)
The value of this proprietary property (property ID 558) determines the maximum period of
time that expires before the object automatically updates its Present_Value. This allows
using the Present_Value as occupancy event input to a constant light controller object.
8.3.5 Constant Light Controller

controller functionality for each DALI channel. Every instance is represented by a BACnet
Loop object.
8.3.5.1 Setpoint
The desired setpoint for the illumination level is configured via the property Setpoint.
8.3.5.2 Operating Modes
