Keypad: AC Power Loss
The alarm keypad display reads, "Ready to Arm" and below it blinks, "Keypad: AC Power Loss". I replaced all four original AA batteries with brand new NiMH rechargeable batteries, cleaned the four terminals on the keypad unit and the four slider connectors on the cradle, re-seated the keypad unit onto the cradle, trimmed off the wiring on both ends of the power cable (stapled to the wall) and reconnected the freshly exposed wires to the cradle and the AC Adapter (named Asian Power Devices originally installed by the A&T technician), and checked that power outlet has power.
After all this, the display still blinks, "Keypad: AC Power Loss". Could it possibly be an AC adapter failure, broken wires in cable, or is there another explanation?
