Aligning Perimiter Microwave Detectors

This one happened about a year ago. I won't name anybody to avoid embarrasment.

We manufacture a System called FG350, which is a microwave perimiter system, consisting of a Transmtter and Receiver which are located up to 200 Metres apart. They are similar in principle of operation to Active infra-red beams, but are higher security Microwave Detectors.

A company had installed them at a site to protect a car compound, but had been unable to align them after repeated attempts. They were required to work at a distance of around 100 metres, which is well within the specified range.

They had then brought them back to their offices where they had tried to set them up at a distance of 10 metres, again with no success. I had therefore been asked to Visit them to establish the problem.

The problem was very quickly established. Rather than having the microwave reflectors pointing towards each other, they were pointing in completely opposite directions!

I simply swivelled each unit 180 degrees, and immediately obtained a good signal.

The installer was slightly embarrased, as you would expect.
