Unfortunatley you are not using any tamper.
You have a pair for power and a pair for alarm only.
I would use resistors, place 4k7 between A and B, and from B to C 2k2
connect to a and c back to the panel and use double pole/eol.
Is there more than 1 smoke detector on the zone?
Just let me know and I will advise of the wiring and placement of resistors, if you don't have any spare 4k7 and 2k2, you should have some 3k3 resistors and you can swap both the 4k7 and the 2k2 for 3k3's instead. You should have a set of all these.
If you have already wired this to the panel, all you need to do is put the resistors in and move wire in B going back to panel to C.
