1.0 OVERVIEW
The A 1707A 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 ve
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 Chipset will be displayed briey before the current time is
shown.
Altronics A 1707A
DS3231 Chipset 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, while the unit
remains in menu mode. On exiting the menu, the timer will check all programmed events and update the status of the
output zones.

07:00:00 Fig 3.2
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.
Not Available
Check Settings 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.
This will clear
all ON/OFF times
Are you sure?
Then you will be asked to press “Enter” to conrm you want to clear the memory or press “Menu” to exit.
Hold ENTER for Y
or MENU for No
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.-
IMPORTANT NOTE:
Ensure power is switched off when adjusting DIP switches.
New settings will be effective when power is switched back on.
4.0 DIP SWITCH SETTINGS
There are four DIP switches accessible on the rear of the A 1707A which are for selecting the backup battery and various
security lockout features (See Fig 4.1).

IMPORTANT NOTE:
The memory must be cleared before using the unit for the rst time.
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.
Switch 1 - Battery Backup
When switch 1 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 1707A 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 1707A requires backup power a backup power supply can be connected to the 24V DC input.

The backup battery is
located inside the unit
and can be accessed by
removing the lid.
Battery type CR2032
Altronics P/No: S 4999A
5.0 BATTERY BACKUP
Inside the unit is the battery used to backup the internal clock chip. If DIP switch 1 is set to “ON” and the unit fails to keep
the correct time after a power failure then it may be possible that the backup battery is at. To replace the battery, remove
the lid and use a CR2032 battery (such as Altronics S 4999A) as the replacement. The location of the battery is shown in
Fig 5.1.
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.
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.
6.0 REAR CONNECTIONS
6.1 24V DC Connectors
DC sockets have been provided for 24V DC input and a 24V DC output. These two sockets are connected in parallel inside
the unit, so either could be used as an input or output or both as inputs. Two sockets have been provided so that the
power can be daisy chained to another device. The Altronics P 6717 DC power lead has been designed for this purpose.
The sockets also have a threaded connector so that the Altronics P 0602 2.1mm DC Plug with collar can be screwed onto
the DC socket so that the DC power lead cannot be accidentally pulled out.

Fig 6.2
6.2 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 anout 250 milliamps, 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).
6.3 Closing Contacts:
These contacts “close” when the output zone is set “ON”. These can be used to trigger devices such as the Altronics
A 1741MP3 Message player.
Fig 6.2 demonstrates an example of how to connect the A 1707A to the A 1741. A 24V DC plugpack is used to power
the A 1707A, the 24V DC output of the timer is then fed into the A 1741 using a power lead with 2.1mm DC connectors
such as the Altronics P 6717. Thus removing the need for another plugpack to power the message player.
The Zone 1 switched output of the timer is then used to trigger a 24V DC bell. As the current draw of the Bell is more
than 250mA a relay board is used to switch an external power supply. The Altronics S 4444 24V Relay Board as shown is
an inexpensive and easily installed option designed for this purpose.
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.
