Got the alarm installed almost 3 years now, all worked fine, until beginning of the week where alarm control unit started beeping at 2:30 every night!!!! Every 30 - 60 sec and carries on for about 30 minutes. This happens in armed or un-armed mode. Doesnt show any fault on display.Now its happening more randomly. Tried to phone Yale, but was holding for 15min...Please help as this is driving me insane!!!!(
