Micro Sd Card (Mp3) - Redback A 4595A Operating Manual

Redback® A 4595A School Lockdown Controller

3.4 Micro SD CARD (MP3)

The micro SD card supplied with the unit has audio files for testing purposes only. These audio files do not meet any Aus-
tralian standards or fulfill any particular criteria.
The audio files must be in MP3 format (they cannot be WMA) and are stored in folders on the Micro SD Card.
NOTE: It is recommended to store only one MP3 file in each folder.
The A 4595A will play the first file it finds in each folder which corresponds to the mode the unit is running in.
For example if "Standby Mode" is activated, the A 4595A will search the "Standby" folder on the Micro SD card, and
then play the corresponding MP3 file. If DIP switch 1 is set to "ON" (See DIP switch settings in section 3.6) the MP3 will be
played in a continuous loop. If DIP Switch 1 is set to "OFF" the MP3 will play only once.
The length of time the MP3 plays for is determined by the length of the actual MP3 file itself.
3.6.1 Installing MP3's on to the A 4595A
• Firstly remove power from the A 4595A and then remove the Micro SD card from the rear of the unit.
To remove the Micro SD card, push the card in and it will eject itself.
The Micro SD card will then need to be connected to a PC, equipped with a Micro SD card reader.
• Make sure the PC is ON and the card reader is connected and correctly installed. Then insert the Micro SD card into the
reader.
• Go to "My computer" as shown in Fig 3.4a and open the Micro SD card which may be labelled Local Disk or Removable
Disk.
Open Local Disk or
Removable Disk
• Once the Micro SD card has been opened you should see a series of folders as shown in Fig 3.4b. These folders relate to
the triggers and modes of the A 4595A. E.g the "All Clear" folder contains the MP3 which is played when the "All Clear"
mode is activated.
NOTE: There is a folder labelled #LIBRARY# which has some samples tones, school bells etc.
NOTE: Some A 4595A models may not have the Fire and Firetest folders supplied on the SD card. If using the A
4597 wall plate (See section 4.3), these folders will need to be added to the SD card.
We will use the allclear folder to demonstrate the installation of the MP3 file.
