Finding a fault in a security system is really a process of elimination. You need to
think laterally sometimes. Ask yourself the question “Why?” at least five times and
you are bound to come up with the reason why something doesn’t wo
rk, or why the
alarm is falsing.
It has been said that “experience is the best teacher”. Making mistakes is the best
way to learn, and hopefully you won’t make the same mistake twice. However, you
should always try to find the answer before ringing up the
supplier of the product.
Quite often the answer is in the Operator’s Manual or the Installation Manual.
Here are a few tips to help you fault find in security system.
