You can also load the files on the VS4810 and play them as a live audio transmission. The downside to this is
that once the message is started, you will not be able to stop it easily. You would program in a device ID with
the type “wireless speaker”, and use the DSC field (Device Special Command) to play an audio file stored on
the unit rather than have you speak the message. The unit will not send alarm messages during this, as the
system prioritizes live audio over message activation. It will keep playing the audio until finished. If you have
to stop it, you would need to turn the unit off. For these reasons we would recommend uploading the custom
audio to the speakers themselves, and just having the GM command activate them.
The format for the 4-digit DSC field is: TTRD
• TT: Two-digit track number. For the VS4810, 01 is the first file you load on it, since there are no built-
in audio files on this unit.
• R: Repeats, 1-9. How many times it will play the audio file.
• D: Delay, 1-9. How many seconds it will wait between plays.
For example, if you load 1 file on the VS4810, and you want it to play twice with a 3 second delay, the DSC
field would be 0123.
The DSC field is also how you would use the telephone line interface if you have it, to dial out to a number
and play a recorded message. Program a device ID you can trigger, leave the code field blank, then enter the
phone number you want it to call in the phone field (with a 1 in front, no dashes or anything). The type will
be phone, and you will use the DSC field to indicate the message to play. When the phone is answered, it will
play the recorded message over the phone line.
