‘Orion Range’
Infra-red Microwave Presence Detector
- Programmed Settings
Model: ODM202
Switch the mains supply OFF first to prevent electric shock.
INSTALLATION
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.
With ambient light
more than the setting
value, the lamp does
not switch on when
someone enters the
room.
With ambient light less
than daylight threshold,
the lamp will be on
100% when someone
enters the room.
After the hold time, the
light switches off
automatically when no
movement is detected.
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:1 and Dia:2.
