External Page with BIOU Interface
Up to two BIOU interfaces can be installed for connecting external page equipment. Each BIOU
can provide up to four unique page zones for a total of eight page zones maximum per system. The
BIOU interfaces can be installed in the main cabinets and/or any remote cabinet. Each BIOU
provides a 600ohm, non-amplified page output and an 8 ohm, 3-watt amplified page output. Only
one type of page output, amplified or non-amplified, can selected per BIOU in a given installation.
The BIOU also provides a control relay which can be used to mute external BGM when the
external page circuit is active (see

A separate external BGM source can be connected to a building's external Page speakers using the
BIOU interface. This enables the BGM sent over the external page speakers to be different from
the BGM sent to telephone speakers (see
connections).
