sometimes on my sigma alarm just as I turn the engine over the alarm chirps once...... Can anyone tell me what this means ? It doesnt happen every time and it is not super lock or forced arm etc. I cant find an answer in the hand book either....

Aha....One for me I believe,

Your alarm is sometimes detecting a voltage drop from the battery when you turn the car over, but not enough to set it off. Some stupid individuals who try and nick stuff from cars think the best way to foil an alarm is to remove the power from the battery, at least it shows you've got a good working backup battery in your alarm....I think this is the reason, otherwise stop pushing the keypad when you turn the key !!!

 

Have to admit to doing that too.

Thanks for that I`ll charge the battery up with an optimate and see if it makes a difference.
