Bypass Connection Examples
Bypass Terminals
The bypass terminals override the vol-
ume control knob, thereby allowing a full
volume page to be heard in the area
even if the front-mounted volume con-
trol knob is set to maximum attenuation.
Bypass can be triggered via a contact
closure or an open collector output.
Bypass Trim Control
The bypass trim control
sets the volume when the
unit bypasses the volume
control knob (maximum
attenuation of
1
2 dB).
In the example below the AUX contacts of the UTI
1
are programmed to close when the
UTI
1’s
Override (Emergency) input becomes active.The AUX contacts trigger the Bypass fea-
ture of the BUFEX allowing a full volume page to be heard regardless of the voume setting of
the BUFEX. See previous page for power and output wiring.
UTI
1
PCM-ZPM
PCM2000
In this configuration the Bypass feature
activates when the zone is being paged,
but allows volume control when the
zone is inactive and background music
is playing. See previous page for power
and output connections.
