ZPI 4 Multi Zone broadcasting interface

The ZPI-4 is a four zone paging system which couples with each telephone and may be a line level signal to a broadcasting amplifier (PA) to send or send directly to speakers via the amplified output.

The ZPI has four balanced audio circuits and is compatible with inputs and outputs of balanced broadcasting amplifiers. In addition, separate volume controls provide for broadcasting and background music. The background can be disabled by zone.The integrated night bell is activated by a potential free contact or bubble voltage from an analog trunk or station port.
