Switching PIR Presence Detector
Manufacturer: CP Electronics
Product Type: Presence Detector
Model Number: EBDMR-PRM
Website: http://www.cpelectronics.co.uk/cp/922
Product Usage Instructions
- This device should only be installed by a qualified electrician, following the latest edition of the IEE wiring regulations.
- The device comes with presence detection as default. To use absence detection, a retractive (momentary) switch must be connected between the 2 terminals on the diagram. Note that this will switch mains voltage.
- Cut a 64mm diameter hole in the ceiling for installation.
- Strip the wires as shown in the diagram. The presence detector does not require an earth conductor.
- Wire in plug/s using the wiring diagram on page 3 as a guide. Connect the plug/s to the detector.
- Tighten the screws to secure the device in place.
Note: The above adjustments can also be made using the optional UHS5 or UNLCDHS handsets. Please refer to the user manual for further details and safety instructions.

- Switched output
- 10A circuit protection if required
- Load
- Momentary push-to-make switch, 230V (for absence detection)
Switching channel is L-Out.
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.
Installation
This device is designed to be flush ceiling-mounted.
- 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.
- Occupancy is best detected when the ambient temperature is different to that of the human body, thus, use within -20 to 35ºC ambient temperature.

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 3 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.

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.
