Contact Closure Zone Connections
NOTE: To ensure proper
operation of all zones, it is very
important to connect the zone
cabling in sequence on controller
and each unit. Remember, start
at your Ieft and work to the right,
not skipping any zones. Refer to
the connectors on previous
illustrations.
The contact closure input and output and signal zone connect to the
controller and zone expansion units are same as with the paging zone
speaker hookups. Refer to figure 3-7. The major difference is the mode
function slide switch, behind the screw down zone connector, is set to
either Contact Closure Output (back setting) or Contact Closure Input (mid
setting), not 70V output (paging signal). Refer to the subsection called
“Switch Settings.”
The output contact closure contacts are rated at 120VAC or 50VDC at 1
amp. It is recommended to have this output control a low voltage relay.
The input signal is a normally open circuit which is momentarily closed
(i.e., pushbutton switch). The input signal sets off a preprogrammed tone
to a particular zone(s).
Each optional zone expansion unit accommodates an additional 16 control
and paging zones, and zones are connected in the same manner as the
controller. A maximum of three zone expansion units can be used which
provide a total of 56 paging zones.
