• Position the detector so that the occupants of the room are normally inside the detection zone.
• Do not install the detector within 1 m of any lighting, forced air heating, or ventilation equipment.
• Do not fix the detector to an unstable or vibrating surface.
• Install the unit as far away as possible from the surface of metal objects.
• The detection pattern illustrated (see ‘Detection Pattern’ on page 1) is based on a mounting height of 2.8 m. A lower
mounting height will decrease the overall size of the detection zone.
Prerequisites
Installation
Connection, Fitting and Set Up
Connect the DALI
terminal blocks.
If required, connect the
external power cable.

In some cases the generic EPS output is referenced to earth.
With some models, you must make a wire
link between the DALI negative terminal
and the negative terminal of the external
power supply, as shown in the figure.

With the circuit switched on the
LED in the sensor will flash red
for 30 seconds.
When the detector is activated the relating light load will
illuminate and remain on for a defaulted time of 20 minutes if
there is no other movement detected.

heck the DALI network connection by selecting the
Identify
function
in Designer or Toolbox
Adjustments to the detector such as sensitivity, On / Off transitions
and illumination periods can be managed using Designer or Toolbox.
Note:
Maximum sensitivity makes the detector unit
extremely sensitive
to movement and may detect through glass, thin walls or partitions. If this
causes a problem, reduce the sensitivity.
When using Designer, connect the PC to the lighting network via a
Helvar router.
When using Toolbox, connect the PC to the lighting network via a
Helvar serial or USB interface.
