Hi All,
It's been a while as I've been obsessed with all things chocolate and bread recently but as we're about to set off on our first 'big trip' I'm back on the Moho subject again.
I have a Hymer Tramp SL 568 and notice the hab door when opened is not triggering the alarm. I have no idea what alarm is fitted although I will look through all the paperwork later.
The cab doors are ok and set it off. There is a sensor on the hab door lock.
any idea's ?

The sensor on hab door could be stuck in the "closed" position if mechanical. Maybe it's not armed if it's possible to have two zones. We assume it used to work, i.e. you open the hab door with the alarm armed and the alarm went off much like you describe the cab doors. Without a few pics (not a good idea to share on a public forum) might be tricky to diagnose...

If you have wireless door contacts check the battery. Also on any type of switch worth checking the reed switches are OK if the glass is broken they won't work

If you have an alarm sensor near the bottom of the frame of your hab door that looks something like this then they sometimes have a habit of the reed switch contacts sticking together.

The majority of alarms fitted to motorhomes are of zero use anyway. They are car alarms, wired into the cab central locking. Thieves know that it is a 2 second job to unlock ducato/boxer/relay drivers door and automatically turn OFF the alarm

This poor design means that the hab door and other lockers are simply an extension of the circuit and prone to very easy failure

I'll need to take a screwdriver to it as the sensor does have a screwplate. I'm wondering whether it's wired through the lock in some way?

Not good to hear but much as I suspected anyway and enforces my decision to get a tracker fitted. I have a bulldog wheel clamp but finding it heavy and a right bugger to fit. I'll need to get the knack of it

Not sure what I have so maybe I'll head over there today and investigate a bit and take some photos

That's certainly not the case with the Autowatch 695 RLC fitted to an Elddis which if you use the key to lock or unlock the central locking it has no effect on the alarms operation as the alarm is only set and unset via the key remote.
The Autowatch 695 RLC is widely fitted to MH's.

You must be referring to those rubbishy foreign MH's :giggle:

The Drivers door is an optional extra on most A Class, and the bigger ones not available at all.

Now you are being silly, the number of A class vans with no doors is totally eclipsed by the majority of vans that are coach built or PVC with the fiat etc cab doors. Punch a small hole below the handle with a sharpened screwdriver and simply depress the lever on the central locking controller. Voila unlocked van

why even bother with that effort then. Chose any one of the plastic windows with the plastic catches

the reason they almost silently appear to unlock and open the door rather than rip a window off is that they are cowards and don't wish to draw attention to themselves. Breaking the catches off an acrylic window is far noisier and dramatic. Guaranteed to be noticed, whereas a person walking up to the door, fish something quite small from their pocket and push it in, in the same area as the lock is perfectly normal. Any casual bystander will immediately forget seeing it. The human brain does that for random everyday actions.

Believe it or not thieves don't wear striped jumpers and carry a bag with swag written on it. They blend right in with people around them
