Hello Acorn, what happened is this:
I disconnected keypad with system in eng mode.
Upon reconnection, had system in Eng mode, then proceeded to wire up. In doing so, I managed to short the 12v connection onto the pcb! there was a slight burning smell. Now what happens is that all the leds light up & no display on the keypad. it seems locked.
Before you mention it, I was lazy, should have first disconnected the keypad wiring at the panel, but there you go.
So I presume its beyond fixing now(:{
regards
