4. CONNECTION
Wire the products as shown in the diagrams. Auxiliary switches are
optional.
An auxiliary switch can be used to turn off the light and adjust the
dimming level (up/down) - on/off.
5. INSTALLATION
The product is designed to be surface mounted on the ceiling or flush
mounted, or directly on a luminaire.
The detector should be sited so that the occupants of the room are
inside the detection area, at a recommended ceiling height of 2.8 m.
The lower the sensor is installed, the smaller the detection range will be,
subject to the parameters shown on the detection diagram.
- For optimum operation of the lux sensor, the lens must be shielded as
much as possible from the light source.
- If flush mounting in a panel > 6 mm thick, remove the bottom of the
retaining clips with a cutter.
- Avoid direct sunlight entering the sensor.
- Do not site within 1 m of forced air heating or ventilation.
- Do not fix to a vibrating surface.

Flush mounting
The product can be mounted using the flush mounting ring as shown.
If flush mounting in a material > 6 mm thick, remove the bottom of the
retaining clips with a cutter.
A 32 mm diameter hole will be required to insert the flush mounting
ring.
Power-up test procedure
When power is applied to the unit, the load will turn on immediately.
Set the timeout to 10 seconds, vacate the room or remain very still and
wait for the load to switch off.
Check that the load switches on when movement is detected.
The unit is now ready for programming.
Surface mounted on luminaire or the ceiling
Use the lugs on the back of the detector to secure it into thin sheet
metal (1 mm max)

6. OPERATION
Detection mode
- Presence: When movement is detected the load will automatically turn
on. When an area is no longer occupied, the load will switch off
automatically after an adjustable time period.
- Absence: The load is manually switched on. When an area is no longer
occupied, the load will switch off automatically after the adjustable time
period has elapsed.
- Manual control: Short press to turn on, short press to turn off, press
and hold for dimming cycle.
In either case, Presence/Absence, sensitivity to movement of the PIR
sensor can be adjusted using the Sensitivity parameter.
HINT: To assist in setting the sensitivity, turn on the
Walk test LED which will flash red when movement is detected.
Switching according to Lux level
Occupancy detection can be made dependent on the ambient light
level using the Lux On Level and Lux Off Level parameters
Regulation according to light level
The detector measures the overall light level in the detection area, then
calculates and dims the luminaire lighting to achieve a preset Lux level
(maintained lighting or daylight harvesting).
