Modification
Single call sub station to receive All Call and Background Music (BGM).
Difficulty Level
1 – Easy – wire connection only.
Components Required
- Capacitor: Aiphone model NP-25V
(33 µfd, 25V, non-polarized).
Instructions
- Install capacitor in series between the number terminal of the master station and the BGR-10A/BG-10C as shown on the diagram.
- All Call and/or BGM require either the BGR-10A (with PS-2410A) or the BG-10C (with PS-12F) to be installed in the system.
- Aiphone master stations with All Call activation capability are:
- LEF-3C
- LEF-5C
- LEF-10C
- LEF-10S
- LEF-1C
- LE-C/CN sub stations do not require the capacitor.
Operation
This system allows communication from the LEF-10C master stations to all other stations in the system. The sub stations can call the master stations by tone and communicate hands-free. All stations can receive music and All Call announcements. Only the LEF-10C’s can initiate All Call announcements and answer the door station.
Capacitor: Aiphone NP-25V (33mfd, 25V, non-polarized). For easy installation, connect one leg of the capacitor to a numbered terminal on the LEF-10C and the other leg to a wire going to the same number terminal on BG-10C.
