Gts, I know its my fault I should have powered down, I've learn't my lesson for the future. I'm 100% sure the control panel is fine, only keypad busted. I've walk tested & tested outputs /bell/strobe, all is fine. I guess I was lucky!
I installed system myself 10 years ago, hasn't skipped a beat.
Would like to keep the system, if you have the 9827, I will appreciate it very much.
thanks
