Peripheral Installation

External Page with BIOU Interface

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 Figures 12-8~12-12for connection diagrams).

Figure 12-9 Single Zone Page Options

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 Figures 12-10) for separate BGM over external Page connections).
