Used with 24V systems, the BUFEX is a multi-purpose
device that can work as a volume control for a network
of speakers, and as a buffer that can drive up to 150
speakers. It also functions as a system expander when
connecting to 100V, 70V, and 25V speaker systems.
To address the needs of emergency announcements,
the BUFEX has a Bypass feature that allows emergency
announcements to be heard at high levels regardless
of the volume setting on the BUFEX. The BUFEX contains
a Bypass Trim feature that allows some adjustment to
the Bypass level.

Bypass Feature
Local volume controls allow people
working in an area to control the level
of paging and background music for
their needs. However, in paging sys-
tems where alert announcements are
made as well as general announce-
ments, local volume controls can be a
problem. When users set volume con-
trols for very low levels or off, the alert
announcements may not be heard.
When the BUFEX’s Bypass feature
is activated (by an external contact clo-
sure), it overrides the local level setting
of the BUFEX and allows important
messages to be heard.
In certain circumstances, full level
audio messages may be overpowering.
The BUFEX includes a Bypass Trim that
allows a maximum 12 dB of attenuation
to the alert message when the local
level is set to 0. As the local level is in-
creased, the Bypass Trim will track this
and increase the alert message level
proportionally.
