Presence or absence detection
The unit ships with presence detection as default
- To change over to absence detection, press and release the external switch 5 times within the first minute of power up. The LED will turn on red for 30 seconds to indicate absence mode has been selected.
- To change back to presence detection, repeat the above procedure – the LED will flash red for 30 seconds to indicate presence mode has been selected.
To use absence detection a retractive (momentary) switch must be connected between the 2 terminals on the diagram. Note that this will be switching mains voltage.
Note: the above adjustments can also be made using the optional UHS5 or UNLCDHS handsets.

Walk towards & walk across explained
Alignment marks
The sensor head has 4 alignment marks. These correspond to the 4 outer passive infrared sensors under the lens. Use these marks to align with aisles and corridors to ensure the best detection characteristics.
Masking shields
The detector includes two clip-on masking shields, enabling precise masking of the detection shape for aisles and corners as well as narrowing the detection diameter.
- Lateral trim pattern for slot style detection.
- Radial trim pattern for narrowing the detection diameter.
Ensure all infra-red (IR) programming is completed before affixing the masking shields to the detector.
Masking shield application
Aisles
Trim the masks laterally to reduce the detection width for aisles.

Installation
This device is designed to be flush ceiling-mounted. See page 20 for additional mounting options.
- Do not site the unit where direct sunlight might enter the sensor.
- Do not site the sensor within 1m of any lighting, forced air heating or ventilation.
- Do not fix the sensor to an unstable or vibrating surface.
Create cut out
Cut a 64mm diameter hole in the ceiling
Wire stripping
Strip the wires as shown opposite. Presence detector does not require earth conductor.
Wire in plugs & connect to detector
Wire in plug/s, using wiring diagram on page 2 as a guide. Connect the plug/s to the detector.
Clamp cable
Continue tightening the screws until the clamp bar snaps out and is tightly engaged against the cable/s. The cable clamp must clamp the outer sheath only
Install detector
Bend the springs up and push detector through hole in ceiling. When fully inserted the springs snap back to hold the device in place.
To avoid injury, take care when bending springs.
Default Settings
- Time out: 20 minutes.
- LUX on level: 9
- LUX off level: 9
- Sensitivity: 9
- Detection: Presence
Adjustments can be made using the optional UHS5 or UNLCDHS handsets.
Testing
Presence Detection
- Power up the sensor. The load should come on immediately.
- Vacate the room or remain very still and wait for the load to switch off (this should take less than 20 minutes).
- Enter the room or make some movement and check that the load switches on.
Absence Detection
- Power up the sensor. Switch the load on.
- Vacate the room and wait for the load to switch off (this should under than 20 minutes).
- Enter the room, the load will remain off until you switch it on again.
