  4. CONNECTION

Channel 1 (switched output) can either be used to switch a set of 

luminaires, or to isolate the mains supply of DALI/DSI dimming ballasts 

(saving on the standby consumption of the ballasts).

Multiple loads can be connected in parallel as long as the maximum 

total load is not exceeded.

Channel 2 (dimmable output) can be used to dim DALI/DSI ballasts or 

dimming transformers.

The ballasts/transformers can be connected in parallel as long as the 

maximum number is not exceeded.

The wiring examples below show common installations using this 

detector.

1 - Halogen lamps
2 -  ELV halogen lamps with 

separate ferromagnetic ballast

3 -  Fluorescent tubes with separate 

ferromagnetic ballast

4 -  Compact fluorescent lamps with 

separate ferromagnetic ballast

5 -  ELV halogen lamps with 

separate electronic ballast

6 -  Fluorescent tubes with separate 

electronic ballast

7 -  Compact fluorescent lamps with 

built-in electronic ballast

8 -  Compact fluorescent lamps with 

separate electronic ballast

9 -  LED lamps with separate 

electronic ballast

10 -  LED lamps with built-in 

electronic ballast

Single channel dimming with manual dimming control

Single channel dimming with manual dimming control

Functions:

 Switching the luminaire according to occupancy and 

maintaining a defined lighting level. Override dimming and switching 

using a centre-biased retractive switch.

Configured for presence detection:

 Turns on automatically when 

occupancy is detected. Maintains the lighting level. Press and release 

the down button to turn off, press and release the up button to turn 

back on. Press and hold the down button to dim down, press and hold 

the up button to dim up. Turns off automatically when occupancy is no 

longer detected.

Configured for absence detection:

 Press and release the up button to 

turn on. Maintains the lighting level. Press and release the down button 

to turn off, press and release the up button to turn back on.
Press and hold the down button to dim down, press and hold the up 

button to dim up. Turns off automatically when occupancy is no longer 

detected.

Channel mode: 

Set to “Switch and dim together”.

Manual control mode: 

Set to “Synchronised 1-position push-button”.
