I have a twenty years old DA Systems Abacus 6P control panel. Each of the six zones is split with two PIR's on each zone. The existing PIR's are believed to be by Comet (but could be Stella or Apollo)and each has an integrated zone spliter so enabling three wire connection(12v+ 0v and tamper). Can you supply a replacement for the PIR's.

Im afraid that system is long obsolete

Thanks for your response, I do know that the panel is obsolete.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.

Im afraid nothing will work as a zone splitter. If you have the cores then you can go more conventional and use eol. If not your looking at an addressable tech like hkc

Many thanks, more thought needed.
