I have just purchased a Auto-trail Cheyenne 840SE 2007 and am trying to find out if I have a Cat 1 alarm fitted. I have in the paperwork a card giving instructions on on how to operate the system. I have checked the MH today and notice on the HAB door and 3 storage lockers there are contacts like you would have on doors to secure buildings... There is an LED on the front of the dashboard, but that may be factory fitted. I don't have separate remote to the main van key. Any ideas please. Thanks
