Hub Controlled Operation
Default DALI Operation
After a factory reset – the AL-WS-DR1-PIR only responds to DALI broadcast commands. There is no group or
short address assignment yet. Since the device accepts DALI broadcast commands – any DALI switch or master
that sends broadcast commands can connect to this device remotely for on/off/dimming – the LED outputs are
controlled by the switch or DALI broadcast packets. In Default mode – no standard DALI ARC level transmissions
occur. DALI received commands are treated like 3-way switch controls.
Auto Virtual 3-Way Operation
If no DALI address is assigned, the AL-WS-DR1-VAC assumes that the device is in autonomous mode, and not
connected to a DALI bus. In this mode, each time there is an On/Off event locally – the device will transmit via
DALI the dimming level using the reserved command 171 in broadcast mode - this will be recognized by other AL-
WS-DR1-VAC as an ARC level command and ignored by regular DALI devices. This allows multiple devices to be
connected as one large, multi motion sensing network controlling a large number of LEDs.
Full DALI Operation
For full DALI operation - connect your powered DALI bus to the DA+ connections of the AL-WS-DR1-PIR. The
device responds to the provisioning commands from a DALI master. In order for addressable functions to work, a
‘short’ address [0 thru 63] needs to be assigned. This can be done by a DALI Master with configuration features.
Once a short address is assigned – the device can be understood to operate as two devices in one.
1) LED driver with DALI control – the LED outputs will have a unique DALI short address after provisioning.
The LED driver outputs are connected to LED’s and each switch can now be individually controlled by DALI
commands from the bus. All DALI 60929-2006 commands are supported. The actual address and group
is defined and can be changed by the DALI master. See below.
2) Dimmer / Switch with DALI outputs – after provisioning – the mechanical front switch in this device is
placed into either short address or Group mode – see below – flipping the switch, or the 3-way remote
switches, or the slider dimming value will cause a DALI command to be sent internally to the LED outputs
as well as externally to the DALI bus.
3) A DALI Short Address Reset command will return the device to broadcast receive mode and disable all
On/Off/Dim transmissions.
Use an AL-DALI-PI or DALI-100 or similar provisioning tool to assign short and group addresses.
