This system provides coupling with a Page/Party ® system. The Electro-Sound system is shown coupled to
party line 5 but can be coupled to any other party line as desired. Switching between page and party lines
is controlled by Electro-Sound handset and headset switches. The power source contains a relay to isolate
systems when no handset or headset is in use.
Only one jack station and one permanent station are shown for drawing simplicity. The power source is
current-limited to 15 operating stations.
Suggested wire colors shown to aid in connection identification. The stations will not function if polarity is
reversed. Cables to and between stations must be kept separate from power cables.
N OTE : An existing Page/Party ® system should already have a line balance assembly. It is shown here in
the event it is relocated to be within 300 feet of the two-way amplifier as recommended.
