    We had a hab service done last week and ever since then every time i try and set the alarm i get a couple of extra beeps and then about a minute later the alarm goes off is an easy fix available or will it have to go back in? :cry:

    thatcham is a security standard (in the case of vehicle alarms) and not the manufacturer. therefore working out what fault it may be is a bit difficult. try resetting the alarm system as per manufacturers instructions and make sure all doors are closed including the bonnet and that the switches havent been knocked.

    on many alarms 2 beeps is a door open warning

    You need to identify the make first.
    Are there any identifying stickers on the windows or key-fob?
    Does the alarm have a bike-rack loop (a cable with a multi-pin connector at one end and a pull-apart link between the two wires at the other?

    I have a Cobra. The beeps on my van normally indicate a door open?

    As journeyman says, they usually beep to warn you of an open door. Usual culprit is the bonnet sensor breaking up inside ....they look ok, but do take alot of grief!

    Take some wire, an insulated pair of pliers and remove the connector from the back of the switch. Bend the wire so is goes into both ends of the connector (using pliers so you don't risk zapping yourself!)

    Place somewhere where it cannot touch anything/tape up with inulating tape. No need to close the bonnet - you have just folled it into thinking it is.

    Reset the alarm, and see if the fault is gone or not. If it has, replace the switch - if not, move onto the next one.:thumb:

    I had a similar problem with my Cobra alarm, and discovered that the door contact on the garage door had become dislodged whilst unloading and was obviously not making contact when the door was closed. I just put the contact back in place and bingo problem sorted. :thumb:

    There's a similar contact under the bonnet too.

    If the alarm has been triggered the inside warning will flash, and it flashes a code which identifies what caused the alarm to be triggered.

    You need to know the model of alarm. You can then find a manual.

    The link has manuals for cobras.

    ...And did you follow Rainbow Chaser's advice in post #7 to check the switch?

    What was the outcome?

    The alarm type is Autowatch 695 can, if the wire had come off would it mean the alarm needs re setting and if so does anybody know how to do it
