That should be irrelevant as the final set confirm switch should be
completely independent of the detection loop and should only set the alarm,
not unset it or disable the detection loop. It sounds like you are wiring it
as a shunt switch instead, which used to be the way to do it until ACPO
released guidance on final set confirm switches and more panels became
available with the facility.

A final set switch should be a non-latching push button wired to the final
set input on the panel and outside the protected area.
