Redback® A 1709 50 Event Weekly Timer
1.0 OVERVIEW
The A 1709 is a versatile timer which has four switched 24V DC outputs and four closing contacts which activate
simultaneously. It permits a total of 50 station (event) switching times. Each can be set to turn on any single day of the
week or on multiple days, from 1 sec up to 24 hours. Switching events programmed for multiple days count as only a
single station (event) and each of the 50 event times may be set to any (but not multiple) output.
Manual override is provided so that any of the four outputs can be set “ON” or “OFF” manually which overrides any of
the event times programmed for that output.
The unit has security lock out of Time Edit, Station Edit and Clear Memory Functions via DIP switch selections on the rear
of the unit.
2.0 OPERATION
On the front of the timer there are 3 groups of LED’s which provide a visual indicator of the status of each of the four
output zones. The red LED’s indicate a zone is in “Auto” mode and therefore the output of that zone will be controlled by
whatever event times have been programmed into the timer. The green LED’s indicate that a zone is in “Manual” mode
and therefore has been manually set to be either “ON” or “OFF” by the user. Once a zone is in “Manual” mode it will stay
in this mode until the user sets it back to “Auto” mode. The amber LED’s indicate the output status of the zone.
On the rear of the unit are the 24V DC switched outputs and four sets of closing contacts. If a zone is set to “ON” the
corresponding switched output will become active and 24V DC will be present at the terminals. At the same time the
closing contact for that zone will short, and stay that way until the zone is again set “OFF”.
(NOTE: the 24V DC outputs switch the voltage supplied to the unit via the 24V DC input connector. Therefore the output
voltage is determined by the voltage supplied to power the unit).
In order to setup the unit to run automatically, the station (or event) times will need to be programmed. There are four
buttons on the front of the timer which are used to program the unit and navigate the various menus.
3.0 NAVIGATING THE MENUS
When the unit is rst powered up, the model number and rmware version will be displayed briey before the current
time is shown.
Fig 3.1
The main screen (Current Time Screen) shown in Fig 3.2 displays the current time. When this screen is displayed the unit
is running in “AUTO MODE” and therefore all outputs will work as programmed. However if the unit is in any of the sub
menu’s (Menu Mode) the unit will no longer respond to any event that has been programmed to occur. On exiting the
menu, the timer will check all programmed events and update the status of the output zones.
Fig 3.2
Monday
07:00:00
SPECIAL NOTE ABOUT “AUTO MODE” OPERATION
If the timer is not displaying the main clock screen, where the time is changing, the unit is not running in “Auto Mode”.
This means it will not be checking any of the programmed events and hence will not activate any outputs automatically.
Essentially this means that as soon as the Menu button is pressed the unit is no longer in “Auto Mode”.
Make sure to return to the main screen by exiting all menu’s when not making changes.

3.1.4 Clearing the Memory
This function will clear the internal memory, erasing any information entered.
Navigate to the “Clear Memory of ON/OFF times” Sub Menu as shown in Fig 3.3.
Press “Enter” to activate this option. If DIP switch 4 is set to “ON” the screen will display the message shown in Fig 3.15.
Fig 3.15
This is one of the security options to protect the information stored in memory. See the DIP Switch settings for more
information. Set the DIP switch 4 to “OFF” and then press “Enter” again. This time you should enter the Clearing the
Memory Sub Menu. The following two screens should be briey displayed.
Then you will be asked to press “Enter” to conrm you want to clear the memory or press “Menu” to exit.
If you press Menu you will return to the Clear Memory Sub Menu.
If you press Enter, the unit will cycle through the memory locations clearing any data stored. This will take a few minutes.
Once nished you will return back to the Clear Memory Sub Menu.
NOTE: It is advisable to now set DIP switch 4 to “ON” to prevent accidental clearing of the memory.-
4.0 DIP SWITCH SETTINGS
There are eight DIP switches accessible on the rear of the A 1709 which are for selecting the backup battery and various
security lockout features (See Fig 4.1).
Switch 1 - Not Used
Switch 2 - Station Edit Lockout
When switch 2 is set to “ON” access to the Station Edit Mode will be restricted. Therefore there can be no tampering of
the Station (Event) times.

or MENU for No
IMPORTANT NOTE:
Ensure power is switched off when adjusting DIP switches.
New settings will be effective when power is switched back on.
IMPORTANT NOTE:
The memory must be cleared before using the unit for the rst time.

Switch 3 - Time Edit Lockout
When switch 3 is set to the “ON” access to the Time Edit Mode will be restricted. Therefore there can be no changes
made to the current time.
Switch 4 - Clear Memory Lockout
When switch 4 is set to the “ON” access to the Clear Memory Mode will be restricted. Therefore there can be no erasing
of the Station (Event) times stored in memory.
Switch 5-7 Not Used
Switch 8 - Battery Backup
When switch 8 is set to the “ON” position the internal battery is connected to the units clock chip. If power is ever
removed the battery will ensure the clock chip continues to run and therefore keep the current time.
NOTE : This battery does not provide backup power to the entire A 1709 unit. The display will not light up and the unit
will not function. Only the internal clock chip will still be supplied power.
If the entire A 1709 requires backup power a backup power supply can be connected to the 24V DC input.
Fig 5.1
6.0 REAR CONNECTORS
6.1 24V DC Connectors
DC sockets have been provided for 24V DC input and a 24V DC backup. These two sockets are connected in parallel inside
the unit, so either could be used as an input or output or both as inputs.
6.2 Interface
These is for future connection of Redback® products. Do not connect leads to these ports.
6.3 Micro SD Socket
This is used for rmware updates (see below for more details). A Micro SD card is not supplied.
To perform an update, follow these steps.
1) Download the Zip le from the website.
2) Remove the Micro SD card from the rear of the A 1709 and insert it into your PC.
3) Extract the contents of the Zip le to the root folder of the Micro SD Card.
4) Rename the extracted .BIN le to update.BIN.
5) Remove the Micro SD card from the PC following windows safe card removal procedures.
6) With the power turned OFF, insert the Micro SD card back into the A 1709.
7) Turn the A 1709 ON. The unit will check the Micro SD card and if an update is required the A 1709 will perform the
update automatically.
The backup battery is
located inside the unit
and can be accessed by
removing the lid.
5.0 BATTERY BACKUP
Inside the unit is the battery used to backup the internal clock chip. If DIP switch 8is set to “ON” and the unit fails to keep
the correct time after apower failure then it may be possible that the backup battery is �a t. To replace the battery, remove
the lid and use aCR2032 battery (such as S4999A) as the replacement. The location of the battery is shown in Fig 5.1.
Battery type CR2032
P/No: S4999A
It is possible to update the �rmware for the A1709 by downloading the relative update version from
redbackaudio.com.au if available.

6.4 Switched 24V Outputs:
These terminals have 24V DC present when the corresponding zone is set “ON”.
These may be used to operate something like an external relay used to turn on a solenoid, a lunch bell, etc.
(NOTE: The maximum current draw per output is about 120 milliamps (internally polyswitch protected), so it is advisable
to run external 24V DC relays instead of trying to drive a 24V DC device directly from these outputs. See Fig 6.2 for an
example of this).
6.5 Closing Contacts:
Fig 6.5 demonstrates an example of how to connect the A 1709 to the A 1741. 24V DC plugpacks (supplied) are used to
power the A 1709 and the A 1741.
In the example shown the Zone Output 2 closing contact of the timer is connected to the Input 1 trigger of the message
player. When Zone 2 is activated by the timer, message 1 of the message player will be played.
