IMPORTANT NOTE:
There are two versions of the
Model 8720 Central Controller. In
one version (not shown) an
added terminal
8(+)
and terminal
9(-)
are used to provide an
additional siren output and thus
duplicate the function of
terminals (7+) and 10(-),
respectively. In the other version
(shown here) terminals 8 and 9
have been eliminated.
