APPLICATIONS
Zone Paging with Background Music & Emergency Override
Programming of the PMX84 for this application can be done by simply opening & downloading a file (page1b.pmx) during Configuration.
This application is identical to the application on the previous page, except that an emergency override signal has been added. The
emergency override signal is connected to Input 8 of the PMX84, and an emergency override switch (or contact-closure) is connected
between the Override terminal and the adjacent ground (
ý
) on the PMX84. Override is programmed to assign Input 8 to Outputs A~D.
Override maintains a higher priority than any of the Logic Inputs. When Override is activated (shorted to ground), all paging & background
music assignments will be shut off and the emergency override signal will be applied to all outputs. When Override is released (no longer
shorted to ground), the PMX84 will automatically revert to its previous settings, and normal operation. The emergency override signal may
be paging, an alarm, or a siren. If no emergency override signal is connected to Input 8 of the PMX84, the Override terminal will still
provide an override function. Under these circumstances, Override will still shut off all paging & background music assignments, but no
emergency signal will be applied to the outputs.
