On / Off Operation
Press the button once to toggle the light on or off. If the light is turned on by the switch during fade out, then the On
Time is doubled
Local and Remote Dimming
Press and hold the switch to dim the LED down. To dim up – hold the switch down until it fades to low, and
continue to hold so it will brighten back up again. If you reach to high a dim level – then release and press again –
the level will decrease.
Auto Gang Operation
If no DALI address is assigned, the AL-WS-DR1-PIR 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 0xDD. This will be recognized by other AL-WS-DR1-PIR 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.
Daylight Harvesting Modes
If daylight harvesting is enabled, the device will increase and decrease the ceiling LED brightness to match the
target “Harvesting” brightness set by the user. Every 10 minutes, the system will compare the light in the room with
the requested level, and adjust up and down as needed. The level will be sent on the DALI bus, allowing a large
number of LEDs to be automatically controlled.
