Glyn Harper Posted July 29, 2008 Report Share Posted July 29, 2008 (edited) When I arm my alarm (Cobra 6422) it buzzes at me for about a minute, with the telltale LED flashing really quickly, and then the alarm sounds after the minute. Any ideas why it does this? There are deffo no doors open. I'm suspecting the microwave sensor is not plugged in properly, but could this be anything else?
