Hi guys, thought you may be interested in this. Like many UK sold Espaces, mine has a Thatcham CAT1 alarm made by Cobra fitted. I read with interest on another renault forum, that you could extend the range at which the key fob would arm and disarm the alarm by adjusting screws in two parts of the Cobra alarm. One is underneath the rear hatch in the roof and the small unit has a screw in the centre. Likewise under the top section of the dash where the ain Cobra unit is fitted, it too, has a screw in the centre of the unit.
The poster on the renault forum suggested you could extend the range at which the key fob would work by turing these screws to the right. IN FACT the only thing this does is to increase the sensitivity of the alarms units, AND if you turn them far enough, you can set off the alrm just by standing within a foot of any door!
Moral of this story is don't believe all you read. The units were installed pre-delivery in the UK by Cobra and ARE properly set up already!!
Correct Colin,
These adjustments are only for adjusting the envelope of the ultrasonic sensitivity, and they should not be touched. If you do you will only usually upset the system and get false triggering. The one above the rear tailgate was often known to fail too, causing the system to trigger when anyone walked close to the car, and one quick way to stop it, was to disconnect that sensor. You should also be aware you can turn these sensors off, so that you can lock the car but leave someone or something like a dog in the car, which will not trigger the alarm by movement, but opening the doors without turning the alarm off will still trigger the alarm. This is also useful when the car is left on a ferry so it can be locked and alarm armed but not trigger owing to movement.
