9.0 MP3 AUDIO FILES and ALERT and EVAC VOICE OVER MESSAGES
The supplied MIcro SD card houses all the MP3 audio files used for the output tones. These files are stored in six separate
folders (see figure 4) and relate to the corresponding output. e.g. the Alert folder houses the MP3 file to be played when
the Alert mode is triggered.
These files can be any length and bit rate, but must be in MP3 format (they cannot be Wav files or AAC files).
(NOTE: only one MP3 file can be in each folder).
There is also a folder labelled “#LIBRARY# which contains a host of sample MP3 files.
The “Voice” folder contains the MP3 audio files played as the Alert and Evacuation messages. There are separate folders
for both the Alert and Evac messages as shown in figure 4.
The messages have to be recordered in MP3 format using any readily available PC software or other means, and then
transferred to these folders.
Fig 4.
10.0 Activating the Voice Over Message:
Voice over messages become active when an MP3 file is present in the relevant folder.
If the voice over message is not required leave the folder empty.
