NOTES:
1. Any LE- or LS- series sub station can be used.
2. Capacitor for All Call is Aiphone model NP-25V: 33µfd, 25V, non-polarized.
Capacitor must be inserted in series between BG-10C and the number terminal on the master station that
is wired to a standard sub station.
3. Background music can be distributed throughout the system via the BG-10C(s). Music source must
provide
an AUX (10K ohm) output. Music is distributed to the master station through the "C" terminal,
showed
wired to "11" above.
4. Each BG-10C can provide music and/or All Call to as many as 11 sub or master stations. Include as
many adaptors and power supplies as necessary to provide enough outputs to the stations in the system.
5. Do not connect "+" terminal between multiple BG-10C adaptors.
