PTIONAL
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.

EPLACEMENT
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 ).
