Can anyone help, when i set my alarm my horn sounds once which according to the book means a door is not closed properly. I promptly checked the doors and found them all to be closed, my first train of though was the switches i've tested all switches and the readings have come back correct, i have noticed the interior light doesn't dim when i set the alarm and after a short while the alarm sounds, has anybody come across this before it's driving me crazy
I would be greatful for any help.
