Why does the alarm on our Swift Sundance go off by itself randomly

[Pigeonpost]

Our alarm seems to just go off by itself, doesnt do it for a while & it will go off several times after re setting.
It's ok for quite a while then it suddenly goes off no apparent reason. The batteries are all fully charged.
Anyone any ideas pleeezzzz.

How long after resetting does it go off?
What year?
Does it have interior sensors?

Give up and get a vanbitz alarm , you know it makes sense

It will be the sensortivity of the ultrasonic sensors in the cab. You need to find the control unit ( black box) for your alarm which will be installed probably within your dashboard. There will be a tiny little adjusting pot that will need a little tweak, but do not use a metal bladed terminal screwdriver as metallic objects can screw the system up. I bought a plastic screwdriver set of EBay. Adjust it about 1/12 of a turn and then try it. Good luck.

Are you sure all doors ,including the locker ones, are fully closed, there may also be a bike rack connection if one is fitted.

last time it went off I reset it, then 10 mins later repeated. Then after half an hour later when werent about (a neighbour rang us) it went off again. Hasn't done it again for 3 days. Have since cleaned all sensors. It last did this months ago so random ?1/
