Walk test
The range of the detector increases without the front cover on. This is why it must be
replaced for aligning the sensor correctly and for testing the outputs. Adjust the range using
the following table and pan and tilt the lens module over the area to record the entire
space. Press the program button to light up the red display and the pulse counter is set to 1
automatically. The device can now be aligned. The red display on the outdoor motion
detector lights up with any detection. This test module is terminated automatically 5
minutes after the last detection. You can also disconnect the power supply and start the
test module again.
Aligning and masking
In the outdoor motion detector, the multifunctional lens produces 7 long range beams and a
curtain of 7 beams at medium to short range. Movements across the beams provide the
best response and the largest detection range, while movements in the direction of the
detector have a weaker performance result. The device detects temperature changes and
movements in the beam grid; therefore objects such as trees, bushes, ponds, heat
exchange from air-conditioners and animals need to be taken into account when
positioning the detector. The detector module has two sliding panels to reduce the
scanning angle. Additional diaphragms are supplied to restrict the beam grid even more
(for example if a minimum scanning angle of 10° is required).
