‘Orion Range’
Infra-red Microwave Presence Detector- Adjustable
Model: ODM201
Important Safety Instructions
•
Please read these instructions carefully before installation and keep safe for future
reference.
IMPORTANT
This product should be installed by a competent person and in accordance with the
current IET Wiring Regulations and Building Regulations.
If in doubt,consult a qualified electrician.
•
Always turn off the mains supply before commencing work.
Our range of PIR microwave presence detectors are designed to reduce the amount of time
lighting is left on unnecessarily, for example if an area is unoccupied or if there is sufficient
natural light.
A presence detector monitors the detection zone for occupancy, using radio waves in the
microwave band (5.8 GHz) if a person is sensed then the detector will automatically turn the
lighting on. When the area is vacated, the lighting will turn off after a preset time delay. Most
of our microwave sensors have a built in light level (lux) sensor which will keep the lighting off
if there is enough natural light available.
Controlling lighting with a presence detector can save up to 60% of lighting energy costs
dependent on occupancy behaviour and the amount of natural light available; our
microwave sensors can also be used to control heating and ventilation.
As this detector uses microwaves, detection is possible through plastic, glass and thin walls
such as office partitions. It will not detect movement through brick, concrete or metal.
TESTING
Dia:3
1. Turn ‘Time’ control fully anti-clockwise, ‘Lux’ control fully clock wise and ‘Sens’ control fully
clockwise refer to Dia:3.
Dia:1
Dia:2
Switch the mains supply OFF first to prevent electric shock.
INSTALLATION
1. Decide on mounting position of sensor
in and screw into position using the two
mounting lugs at either end. (ensure there
is no wiring/gas/water services directly
behind the screws) refer to Dia:1.
2. Connect the mains in and load out wires
according to Dia:2.
2. Re-connect mains supply, allow 30 seconds for the sensor to warm-up, and then per
form a walk-by in front of the sensor; lamp should turn on and stay on for
approximately 10 seconds, and will go off if no further movement is detected.
Note:
Please refer to Data Sheet on the GreenBrook website -
