We got the Strikeback alarm system installEd last June and happily used it during the summer but now after a few months of not using the motorhome we are travelling again but have forgotten how to arm/disarm the alarm. I think (but please correct me if I’m wrong) to arm/disarm from outside it’s one short press on the small button, whereas to arm/disarm in sleep mode it’s one long press on the small button. Am I right?
