Audio Program

The AlphaCom system is prepared for distribution of audio programs. There must be an external audio source as input to each program, a radio, CD-player, alarm device or other sound input.

A number of inputs for audio programs are available, depending on the system configuration. By default 6 audio program inputs are available via the APC board for the AlphaCom E20 and AlphaCom E26, and 2 audio program inputs for the AlphaCom E7. The number of audio program inputs can be expanded by using AGA board.

Audio Program selection

To select a program, dial the program number (default 801 - 806, 8101 - 8132). The program is temporarily disconnected by outgoing and incoming calls, but remains on during Group Calls and All Calls.

To switch off a program, press the C-key or dial 800.

When lifting the handset the dialing tone is normally heard, replacing any program. To listen to the program with the handset off, simply hold the M-key down while lifting the receiver, and the dialing tone is not turned on.
