Aiphone BG-10C Telecommunication Equipment

The BG-10C is an All Call and Chime adaptor for the Master Sentry Series. It has a built-in All Call amplifier, chime generator and input for background music.

A call from the door station sounds a 4 stroke chime at all master and sub master stations. To answer, select the illuminated station button on the master, press the "talk" button and speak to the door, release the "talk" button to listen. The person at the door station speaks hands free.

The voice and music volumes are adjustable at LEF-C masters. If music is included in the system it will mute automatically while communicating within the system or to the door station.

To place an "All Call", press and hold the "All Call" button while making an announcement. A short pre-tone will precede the All Call at the other stations. There is no talk back while placing an All Call. However, other masters and sub masters can respond by using their "All Call" button.
