Using the Audio
Programming Set up
The Audio channels must be mapped to alarm groups using menu 56.7. This allows the Galaxy panel to know
which audio channel to send to the alarm receiving centre following an alarm activation. In this menu, its also
possible to specify which type of alarm events will result in listen-in operation.
In Use
The audio system continuously records the audio from all channels in a 10 second loop. When an alarm
activation occurs, the audio form the specified channel stops recording and the audio from the time of the
alarm is saved, including a few seconds from before the activation of the detector. The panel will dial the
Alarm Receiving Centre normally and transmit the alarm message and then stay on the line to allow the opera-
tor to listen to the audio. The Galaxy system will automatically select the specific channel to be transmitted and
play the live audio initially. The operator has three control options using a DTMF telephone keypad;
1: Talk to site
2: Listen to recorded audio from the activated channel
3: Listen to live audio from the activated channel
99: End call
