In the old heavy relay panel days pre80's  the battery was just stand
by duty no low battery indicator most panels.and 120 vac was taken to
box to a heavy wound transformer which could run several sirens.
When electronic boards came about the battery became integrated to the
board  to provide the energy needed to run the sirens. and 120 runs to
a small wall transformer.
after changing battery it could take up to 24 hr till battery is
floated to proper voltage and panel sees it.
aprox 13.5 most panels.
