    I think what you are trying to do is build a burglar alarm. Maybe you want a time delay to give you time to open the door and shut the alarm off before the siren sounds. Or maybe you want the alarm to sound like 15 minutes and then shut off. Do a search for burglar alarm circuits and you will find a few. Don't try to reinvent the wheel!

    It's an add on system to my original car alarm
    I have added additional sensors to the alarm which I need to work with it
    Yes I know I could fit an aftermarket alarm
    But if I can get the original alarm to work with it I will
    I like a challenge and I have not been defeated yet and I plan not to be bet with this ome
