Default sigma keeps going off for no reason?

I have a blob eye for the last year and never had a problem with it before but today every time i lock it give it 30seconds and the alarm go's off. I have open and shut every door,boot and bonnet and even pressed all the switches to see if they have bust but the problem still persists.
Please help or will have to leave the car unarmed

Looking at the current weather you could have some moisture on one or more switches that makes it think the door is open. Used to get similar on my bonnet switch added some protection to stop water getting on it no problem since. That was on a clifford alarm and it would beep to say that a door was open.

I had a sigma on my last car and the connectors on the bonnet switch corroded causing it to register as open. Changed the switch (couple of quid) and job was done

Do you know if you can get it read by a dealer to see which switch is faulty?
I think i may make a few calls tomorrow

God knows mate. you can book it in to a sigma dealer they should be able to plug in and see what switch is triggering it but not 100% sure. I think that would be your first bet rather than spending £££ on replaceing ecu.
