Installation

This device is designed to be flush ceiling-mounted. See page 12 for additional mounting options.

• Do not site the unit where direct sunlight & artificial light might enter the sensor.
• Do not site the sensor within 1m of any forced air heating or ventilation.
• Do not fix the sensor to an unstable or vibrating surface.
• Occupancy is best detected when the ambient temperature is different to that of the human body, thus, use within -20 to 35ºC ambient temperature.

1. Create cut out
   Cut a 74mm diameter hole in the ceiling.
2. Wire stripping 
   Strip the wires as shown opposite. Presence detector does not require earth conductor.
3. Wire in plugs & connect to detector 
   Wire in plug/s, using wiring diagram on page 3 as a guide. Connect the plug/s to the detector.
4. 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.
5. 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.
   Caution: To avoid injury, take care when bending springs.

Head position & locking

1. Remove metal locking clip from rear of unit.
2. Set sensor head position to 90º for maximum detection range. Push clip into position shown in the adjacent diagram to lock head. To remove clip, lever out with a small screwdriver.
   Caution: Sensor head position < 90deg may result in varying detection range & sensitivity.
3. Mount the detector centrally above the doorways for optimum detection as shown in the above image.
4. Mount the detector as close to the doorway as possible for precise movement detection and high sensitivity.

Default Settings

• Time out: 20 minutes.
• LUX on level: 999
• LUX off level: 999
• Sensitivity on: 9
• Sensitivity off: 9
• Detection: Presence

Adjustments can be made using the optional UHS5 or UNLCDHS handsets.

Testing

Presence Detection

1. Power up the sensor. The load should come on immediately.
2. Vacate the room or remain very still and wait for the load to switch off (this should take less than 20 minutes).
3. Enter the room or make some movement and check that the load switches on.

Absence Detection

1. Power up the sensor. Switch the load on.
2. Vacate the room and wait for the load to switch off (this should under than 20 minutes).
3. Enter the room, the load will remain off until you switch it on again.
