Filenames
SA models of the PM will recognise files of the above types with the following
filenames:
Message files:
M_
x
.mp3
or
M_
x
.wma
Chime files:
C_
x
.mp3
or
C_
x
.wma
In both the message and chime filenames,
x
must have a value between 1 and 8. Thus
valid message filenames are
M_1.mp3
to
M_8.mp3
, and valid chime filenames are
C_1.mp3
to
C_8.mp3
(or their *.wma equivalents). All other files on the memory
card will be ignored.
The sound file
M_1.mp3
(or
M_1.wma
) will be played when MESSAGE button 1
is pressed; the remaining sound files correspond numerically to the other buttons in
exactly the same way.
The sound file
C_1.mp3
(or
C_1.wma
) is always used as the pre-announcement
page chime. Pre-recorded messages may be preceded by either
C_1.mp3
or
C_2.mp3
(or their
*.wma
equivalents). Additionally, any chime file may be assigned
to a zone group to precede a pre-recorded message. See “Chime settings – SA
models only
l
” on page 39
for details of how to configure chime settings, and
“Assigning a chime to a zone group (SA models only)
y
” on page 34 for details of
chime assignment to zone groups.
Filenames
M_5.mp3
to
M_8.mp3
and
C_5.mp3
to
C_8.mp3
(or their
*.wma
equivalents) will be ignored by a PM4-SA.
It would be common practice to copy sound files to the memory card so that they are
either all in the root directory, or the message files in one folder in the root and the
chime files in another. These arrangements are not mandatory, and the PM-SA will correctly
retrieve the required files from any folder location on the card. However, slightly faster
operation will result by placing all sound files in the root directory.
