Hi Peter , many thanks for the tip regards my old wickes branded rascal super hard wired alarm. It has brought it back to life.
Hi James, "But very little with on board keypads most people have remotes now" If you mean having separate hard wired remote keypad. I'm happy to have one of these. Any particular brands/ models you can suggest .
Even though control panel is working again, it has caused occasional false alarms always on hot days over the last year or two and I really think its time to retire it. When visually inspecting the pcb yesterday there was signs of overheating on far right side of the board by an onboard small battery and metal heatsink that comes out the back of the pcb . Whether this was part cause of the historical false alarms on hot days, or the unit acting dead after the power cut, I am unable to say
