PAGING TRIGGER OUTPUT
The PR-4Zi is equipped with a +12V paging trig-
ger output (Figure 8) that switches on during a
page. This output can be used to trigger an
external amplifier, muting device, or other
peripheral associated with paging. (Paging
peripherals are discussed on page 14.) MUTE INPUT
The PR-4Zi system mutes when a +12VDC signal
is applied to the mute input (Figure 8). This
allows connection of external paging or muting
devices.
