REDBACK A 1717 Message Player User Manual

REDBACK A 1717 Message Player

IMPORTANT NOTE:

Please read these instructions carefully from front to back prior to installation. They include important setup instructions. Failure to follow these instructions may prevent the unit from working as designed

OVERVIEW

• The A 1717 is an MP3 based message player housed in a compact flange mount aluminium enclosure and offers playback of four MP3 tracks. Ideal for custom programming, tones, messages or music for use in interactive displays, security, cus-tomer entry and emergency evacuation announcements.
• When combined with a Redback A 1708/S 0080 timer it can be used to play back scheduled messaging. The included Micro SD card is preloaded with standard tones, including bell, bing bong, siren and pre-announcement chime, plus Australian Standard alert and evacuation tones (complying to AS1670.4).
• Playback for each track can be activated by a closing set of contacts. Contacts may be configured between alternate or momentary action.
• Trigger 4 contacts can be configured to provide a cancel playback switch.
• A 24V DC switched output is activated when any message is active. The unit is supplied with a 24V DC 1amp power supply.

INSTALLATION

• Power requirements: The A 1717 needs a minimum of 24VDC at 300mA to work correctly. Maximum working voltage is 30VDC, do not exceed 30VDC as it will cause permanent damage to the unit. The power is connected via the 2.1mm (tip positive) DC socket on the rear of the unit or via the euro block terminals (see fig 2).
• Output: Output is via the stereo RCA connectors on the rear. Output level is nominal 500mV but is related to the recorded level of the MP3.
• Input triggers : The input triggers are activated by closing contacts on the rear of the unit whether by a normally open switch or a timer or controller.
• Switched output: The switched output terminal is triggered when any zone is activated. The voltage output is the same as the power supplied to the unit. ie if the A 1717 is powered by 24V, the switched output voltage will be 24V.

PLAY MODES

• Alternate: When the A 1717 is in Alternate mode (DIP1 switch1 OFF) (see Fig 3) the closing contact must be held for the duration of the MP3 play time, if it is released before the MP3 ends the MP3 will stop playing immediately. If the contact is held closed continually the MP3 will continue to loop over and over until the contact is released.
• Momentary: In Momentary mode (DIP1 switch1 ON) (see Fig 3) a momentary closing contact or pulse on the trigger pins will activate the MP3. The A 1717 will continue to play the MP3 till it finishes and will stop playing and wait for another trigger activation.
• To stop an MP3 playing when in Momentary mode the Cancel trigger is used. A momentary closing contact on the Cancel trigger will stop the MP3 playing (it is recommended that the Cancel contact be held closed for up to 2 seconds to ensure the MP3 stops playing)

FRONT PANEL CONNECTIONS

1. Volume
   Use this to adjust the volume.

2. Message Active Indicators
   These LED’s indicate when the associated message is playing. The messages are activated by using the triggers on the rear of the unit. (See Fig 2 for details.)

3. DIP Switches
   These switches are used to enable various options. See section 7 for more details.

4. Micro Micro SD card slot
   The Micro Micro SD card which has the messages (in MP3 format) to be played is inserted here. The Micro SD card can be a maximum of 16GB.

5. Power Led
   This LED indicates when the unit is ON.

REAR PANEL CONNECTIONS

1. 24V DC Input
   Connects to a 24V DC supply with at least 0.5 Amp current capacity. (Please observe the polarity)

2. 24V DC Input
   Power is supplied to the unit via a 2.1mm (tip to positive) DC socket. The input voltage must be between 24-30V DC.

3. Pluggable 12-30VDC switched output
   Connects via Euroblock screw terminals. Please observe correct polarity when connecting.
   The switched output terminal is triggered when any message or tone is activated. The output voltage is the same as the power supplied to the unit. ie if the A 1717 is powered by 24V DC, the switched output voltage will be 24V DC.

4. Message 1-4 Triggers
   The message triggers are activated by closing contacts on the rear of the unit whether by a normally
   open switch or a timer or controller. The triggers can be set to Momentary or Alternate triggering. See DIP SW settings. Trigger 4 also acts as a remote cancel when DIP switch 2 is set to ON.

5. RCA Stereo Line Output
   Connect these outputs to the output amplifier. Output level is nominal 500mV but is related to the recorded level of the MP3.

INSTALLING MP3 FILES

You will first need to remove power from the A 1717 then remove the Micro SD card from the front of the unit.
To remove the Micro SD card push the card in and it will eject itself.
In order to access the program, the Micro SD card will need to be connected to a PC. You will need a PC or laptop equipped with an Micro SD card reader to do this. If an SD slot is not available then the Altronics D 0371A USB Memory Card Reader or similar would be suitable (not supplied). Step-by-step guide to installing an MP3 into Trigger1 with a Windows-installed PC

• Step 1 : Make sure the PC is on and the card reader is connected and correctly installed. Then insert the Micro SD card into the reader.

• Step 2 : Go to “My Computer” or “This PC” and open the Micro SD card which is usually marked “Removable disk”. In this case it is named “Removable disk (J:) as shown in figure 3.

• Step 3 : Open the Removable Disk and you should get a window that looks like figure 4.
  The contents of the Micro SD card include a Library folder of sample MP3 files and four folders for the trigger MP3 files. These four folders correspond to the triggers on the rear of the A 1717.

• Step 4 : Open the Trig1 folder and you should see an MP3 file which could be named Trigger1.MP3 as shown in figure 5.
  This MP3 file needs to be deleted and replaced by the MP3 file you want to play when you activate trigger1. The MP3 file name is not important. But it is important that there is only one MP3 file in the trig1 folder.

• Step 5 : Delete the trigger1.MP3 file and replace with the MP3 file of your choosing which in our case is Trigger1Music.

• Step 6 : Check the properties of the MP3 file.
  NOTE the new MP3 file cannot be Read only. To check this, right click on the MP3 file and scroll down and select Prop-erties, you will get a window that looks like figure 7.
  Make sure the “Read Only” box has no tick in it.
  The new MP3 is now installed on the card. Repeat these steps for Trigger2 to Trigger4 if you need to.

• Step 7: The card can be removed from the PC following windows safe card removal procedures. Make sure the A 1717 is OFF and insert the Micro SD card into the slot in the front; it will click when fully inserted. The A 1717 is ready to use.

DIP SWITCH SETTINGS

• SW 1 – Momentary or Alternate triggering
  Alternate: When the A 1717 is in Alternate mode (DIP switch1 OFF) the closing contact must be held for the duration of the MP3 play time, if it is released before the MP3 ends the MP3 will stop playing immediately. If the contact is held closed continually the MP3 will continue to loop over and over until the contact is released.

• Momentary:
  In Momentary mode (DIP switch1 ON) a momentary closing contact or pulse on the trigger pins will activate the MP3. The A 1717 will continue to play the MP3 till it finishes and will stop playing and wait for anoth er trigger activation.
  To stop an MP3 playing when in Momentary mode the Cancel trigger is used (check DIP switch 2 settings). A momentary closing contact on the Cancel trigger will stop the MP3 playing (it is recommended that the Cancel trigger be held closed for up to 2 seconds to ensure the MP3 stops playing).

• SW 2 – Cancel Trigger Option
  When DIP switch 2 is set to ON, trigger 4 acts as a cancel trigger.

• SW 3-4 – Not used.

TROUBLESHOOTING

• NO Power (Power LED does not illuminate):
  • Check power supply DC jack is 2.1mm and not 2.5mm size.
  • Check power supply voltage is 24-30VDC.
  • Check power supply is a DC output, not AC.
• How do I cancel a trigger?
  • Check DIP switch 2 is set to ON. Trigger 4 then becomes a cancel trigger.
