Many thanks, more thought needed. Regards Robert

Thanks for your response, I do know that the panel is obsolete. It is replacement pir's for use with this control panel which I am trying to find. The original, believed to be Comet or Apollo and possibly made by DA have a built-in zone splitter so that two pir's can be wired to one zone on a three wire system. So I am looking for any make of pir with built-in zone splitter OR a zone splitter which could be wired to the zone in the control box. Are you able to help me with this? Many thanks. RobertS
