OPERATING INSTRUCTIONS
Distributed by Altronic Distributors Pty. Ltd. Perth. Western Australia.
This simple to operate digital timer allows numerous
variations of ON/OFF cycles every 24 hours. It can be
configured to 14 on cycles every day. Additionally , it
may be programmed to operate on any combination of
days ( ie. weekdays or weekends). The on duration is
variable and can be set from 1 second to 23 hours 59 min-
utes and 59 seconds. It is ideal for programming period
breaks in schools or change of shift bells in factories and
work places. The in-built digital clock can be set to one of
three modes of operation, manual , automatic and off. In
the manual mode you may override any programmed
setting , the automatic mode switches on at the pre-pro-
grammed times and the off mode disables the pre pro-
grammed on times.

OPERATING INSTRUCTIONS
To install and operate the unit you will need to
programme the timer as follows.
1) Set the current time and day .
To set the current day or time press the key to
clear the entire memory. Hold down the CLOCK key and
press either the DAY, HOUR, MIN or SEC key
continuously until the desired day or time is shown.
Then lift your finger off the CLOCK key to start the timer
operating.
2) Set the ”ON” duration for all programs
Press TIMER key, the display will show :
Set the duration of all the programs (T1) by pressing
HOUR, MIN and SEC keys until the desired “ON”
duration is displayed. It is recommended that you use
durations of no more than 1 second for a single chime
tone. For longer chime durations you will need to set dip
switch 3 to ON as well as programming the ON duration
for a longer period.
To review the programmed duration , press the timer
button when in timer function.
3) Set the programmed “ON” times.
After setting the ON duration, press the TIMER
button again to bring up the first “ON” program.
Use HOUR , MIN and SEC buttons to set the first
program start time. Use the DAY button to set the
desired day or sequence of days this program will
operate on.
You may then press TIMER again to set the “ON” time
for programs 2 - 14.

To exit programming press the CLOCK button , this will
return you to the timer function.
To review a programmed “ON” time press the TIMER
button until the program you wish to alter is displayed.
4) Switch the unit to “Auto” mode.
For the programmed “ON” times to operate the unit
must be switched to Auto mode. Use the button marked
MANUAL until the dash indicator is above the word
AUTO. In this mode the programs will function at the
prescribed times and days.
5) Use of Manual or Off
Manual operation allows the user to override a program.
To use the timer in manual mode press the MANUAL
key until the dash indicator is over the word On.
This will turn the timer on. The timer will stay triggered
until you manually set the timer to the “OFF” position.
To set the timer to the off position press the MANUAL
key until the dash indicator is over the word Off.
Chime Tone Switch Settings
To set the tone for “ON” cycle , use the dip switch setting
table to obtain the type of tone you wish to output.
The factory setting for the chime tone will be single Bing.
Dip switch 4 makes the alert/evac tone cycle
continuously after it is triggered or stay on only while the
Alert/evac button is held down.
To enable the alert /evac to operate continuously switch
dip switch 4 to ON. Note that this will be factory set to
OFF.
REAR WIRING CONNECTIONS
The connections on the rear of the unit require some
explanation in order to set up for continuous trouble free
use.
The 10 way pluggable terminal is labelled Evac, Alert,
Chime, 24V Out and Timer 24V Out.
The terminals activate the assigned tone, e.g. if you want
the ALERT to sound from a remote location the contacts
may be connected to a normally open switch which when
pressed will trigger the ALERT tone and will then sound
as if the ALERT button on the front panel was pushed,
and the same applies to the EVAC and CHIME terminals.
The 24VDC switched out terminal has no output until a
button or the timer activates a tone. When a tone is acti-
vated 24VDC is present across the positive and negative
terminals .
There is a switch next to the Timer 24V Out terminal on
the rear of the unit. This allows you to select whether the
timer “ON” cycle triggers the Timer 24V out contacts or
the chime. If this switch is in the “Up” position , the timer
will cause 24VDC to appear across the “Timer 24V out “
contacts. In the “Down” position , the timer will trigger
the chime.
Note : this switch will be factory set to “Down”.
The RCA Sockets are line level (1V) outputs, which are
run to an amplifier or mixer input.
Power Supply
The power for the unit may come from either 24VDC or
240 AC , for 240V operation simply plug the 240V power
cord into the socket labelled 240VAC.
For 24VDC operation , use the terminal marked 24VDC.
Caution: The 24VDC is polarised and may cause dam-
age to the unit if not connected correctly. The polarity is
marked on the unit, just under the terminal.
Power only needs to be in one form either AC or DC to
work. Both 24VDC and 240VAC can be connected at the
same time (for battery backup).

The volume controls can be found on the rear of the unit,
these should be adjusted with a small phillips head screw-
driver or adjustment tool.
Chime Volume controls the output level of the Chime.
Voice Over controls the level of the optional Voice Over
module (A 2072) if installed.
Alert/Evac Volume controls the level of the Alert and Evac
tones.
Adjust the output volumes to the desired levels.
THE OPTIONAL VOICE OVER MODULE
The A 1700 timer panel has the option to fit the A 2072
voice over module. This will add a voice message to the
evacuation cycles when the evacuation cycle is triggered.
Use with the A 1700 Timer and tone generator
Connection to the A 1700 is via the 5 way keyed header
cable (JP1). The Voice-over Module will play a recorded
message twice in succession after every four evacuation
cycles. The volume control on the A 1700 Timer , labelled
“Voice over level” is used to vary the volume ratio between
the evacuation tones and the voice playback.

BATTERY REPLACEMENT
Periodically the CR2302 lithium battery located within the
time clock (Altronics part No. S 4999) should be replaced,
this should not be necessary to be done more often than
once in 4- 5 years , or should the timer begin to loose pro-
grams or time. To replace the lithium battery in the unit,
disconnect power to the unit. Open the lid and peel off the
label on the rear of the timer. You will then see a screw type
battery cover. Un-screw this cover and remove the old bat-
tery. Checking that the orientation is correct place the new
battery in the timer and screw down the cover. The panel
should now have a reading on the display.
You will need to re-programme the settings on the timer
(refer to that part of the operating section for instructions on
re-programming the settings on the timer ).
