The alarm went off and the keypad was completely dead. It stopped after about 10 minutes and the pad and all the sensors are dead, but the input light is on at the power supply. Is it a fuse problem or what?
If there are any LED indicators on the sensors/keypad and they aren't lit up, it sounds like a fuse could be blown, or the power supply feeding the sensors may be faulty.
