SPEAKER SWITCHBOARD

The speaker switchboard allows for the use of an I/O source to be switched. The continuous audio source “A” is interrupted by the “B” audio source. Typical uses are with voice annunciator, intercom, and elevator music.

Note:
Source A is the audio signal which normally plays continuously and is the signal to be interrupted.

Source B is the audio signal that is to be played upon interruption either by its presence or upon door strobe activation. This interruption mode is determined by the JP1 jumper setting.
