Marquis AS Devon Alarm

Can anyone tell me what model of Corgi Alarm is installed on AS Coachbuilts when sold by Marquis Sussex, Marquis do not fit alarms themselves. also how do I deactivate the interior motion sensor when I set the alarm. 

If alarm was fitted by Marquis, surely they can tell you what model. I've never heard of a Corgi alarm and nor has Google, do you mean Cobra alarm? If a Cobra I can possibly help.

Sorry Paul. Yes it is a Cobra Alarm. typing error. I contacted Marquis at East Sussex and they said they have alarms fitted by Auto solutions of Eastbourne but when I got in touch the fitter was on holiday and the person that I spoke to said no one else could help. I can download a manual from www.corgi-at.com if I know the model number.
Thank You

My Cobra is a 4615, not fitted by Marquis or Auto Solutions but by a local guy.
With mine , switch ignition on and immediately off, then within 5 seconds press dashboard alarm button and hold down until flashes once, then press set button on fob. Wait 25 seconds for alarm to set, then wave hands in front of sensor to see if it has worked.

Thank you for that information, Paul, I will try that tomorrow, don't want to disturb neighbours tonight. Best Wishes and Thanks again. Peter c

Just remembered - when you switch on ignition, you may get a buzzer sounding, it will be you 'step out' buzzer if you have your step out. It catches me every time!

Thank you Paul, Very helpful and it works. Happy Motorhoming. Peter C

Glad to help.
