Sorry for all the thick questions.
If you are sure this is a switched output,
You need to wire this 12 v output to a suitable relay(12volt dc, into the coil terminals, normally marked up A1 and A2), run a cable to the control panel, on the relay use 1 core to the common, and another core to n/o. then at the cntl panel end, use the same 2 cores into open and common.
should work.....
