Installation
These instructions will step you through
setting up and installing the A 2083.
Setting Up the System
Set DIP switches to enable/disable 4 spe-
cific system functions.
Please read instructions first,you may not
need to alter any DIP switch settings
DIP switches are located inside the Master
Switching Unit (Switch Box) to the left of
the power switch ( see figure 1). The lid
must be removed to set the DIP switches
Switch 1 (Priority Select): When enabled,
paging station 1, plugged into the
Microphone Station 1 socket (rear of
Master Switching Unit) will override all
other paging stations. This is factory set to
ON. ie: in this position Input 1 has priority.
Switch 2 (Pre- chime): Provides a two tone
announcement chime to all zones being
paged. Factory set to OFF.
Switch 3 (All call): Enables the ALL CALL
button on the paging station to page all
zones when selected.
When OFF the all call function is disabled.
Factory set to ON.
Switch 4: This switch is not required.
Factory set to OFF.
Paging stations
These are connected from the switch box
RJ45 socket on the paging station to the
RJ45 socket on the Master Switching Unit.
Microphone Station 1 socket must be used
for Microphone 1 priority. See Priority
Select section above.
Use Cat 5 cable for wiring the paging sta-
tions, Altronics recommends part number
W 2760. Maximum distance from paging
station to Master Switching Unit is 300
metres. For wall plates Altronics recom-
mends the use of part number D 5110
(single) or D 5112 (dual)
2 paging consoles can be daisy chained on
the one input if desired. See figure 2 for
details.

Be very careful to make sure no strands
of wire from cabling are shorting
between terminals on the rear connec-
tors, short circuits can cause the master
switching unit to stop working.
Incorrect Dip Switch Settings
For correct operation ensure internal
DIP switches are set correctly prior to
power up.

Background Music (BGM)
If you wish to play BGM, you must con-
nect a background music source. This can
be a CD, Tuner etc and is connected to the
"Background Music In" RCA sockets on
the rear of the Master Switching Unit .
Each zone requiring background music
must be switched ON from the "Zone
BGM Selector" switches on the front panel
of the Master Switching Unit.
Each zone output is a low impedance bal-
anced signal suitable for feeding directly
into a power amplifier of suitable power
rating.
As the signal is balanced, the amplifier can
be remotely located with the use of a
shielded 2 core audio lead. This enables
the amplifier to be located up to 100m
from the switch box.
Pre-installation Power Up.
Prior to installing the unit in it's perma-
nent location it is important to carry out
some preliminary tests.
Connect power to the Master Unit. Ensure
all paging stations are plugged in. Switch
on at the Master Switching Unit. Power for
the paging stations comes from the Master
Switching Unit. Ensure all zone amplifiers
are switched ON.
Set amplifier volumes to 1/2. Make sure
the background music source is on.
Background music should be heard in all
zones with "Zone BGM Selector" switches
(front panel of Master Switching Unit )
turned ON .
Paging station Operation.
To page a "zone" press the switch for that
zone, the LED associated with that zone
will flash.
If more than 1 zone is to be paged , press
additional switches until all the desired
zones are selected.
If you have selected a zone you don't want,
press the switch for the unwanted zone
again and it will cancel.
To page the selected zones, press and
HOLD the"push to talk" switch and speak
into the microphone.
To end paging, release the "push to talk"
switch. The selected zones will automati-
cally cancel after 10 seconds and music
will commence to selected zones. You can
also press the “cancel” switch to cancel
zones selected for paging.
All Call This function allows paging to all
zones. Press “all call” then “push to talk”
switches to page all zones. Release “push
to talk” to end paging.
Cancel Press “cancel” to switch off all
selected zones.
Storing groups of zones
Two function keys (store and recall) are
used for programming groups of zones
into a single number recall just as your
telephone has a single button recall for a
telephone number. Each paging station has
memory to store up to 16 different groups
of zones. Each station in the system can be
individually programmed to suit the oper-
ators requirements.
Store. To store a set of zones into a single
number recall, first press all the zones
required so the zone LED's are flashing.
Then press "store" then press the number
(1 to 16 ) to store the selected group.
Recall. To recall any group of stored
zones press "recall" then the number
(1 to 16) of stored groups. Press "push to
talk" to page . Releasing "push to talk"
ends paging.
System Busy. The system busy LED will
flash when other paging stations in the
system are paging.
Wait until the "system busy" LED extin-
guishes before selecting other zones to
page. The exception to this is when
“microphone priority 1” is enabled (See
Dip Switch Setup, Page 1).
System adjustment.
Volume levels of paging, BGM and chime
can be adjusted. To adjust these levels (see
figure 6) use the trim pots inside the mas-
ter switching unit. Only to be adjusted by a
qualified installer or service person.
Sensitivity of the paging microphone can
be adjusted using a screwdriver via the
rear of the paging console.
Switched 24V Output. For the operation
of fire evacuation override relays in atten-
uators etc. a switched 24V output is pro-
vided. This is referred to as “external relay
out” on the rear panel.
This is activated every time a zone is
paged to provide 24VDC output from the
external relay. The unit is factory set to
"fail safe" mode for the external relay.

About Fail-safe mode.
It is often necessary to override the
volume control in an evacuation
control system during an
emergency situation. In failsafe
mode a relay is used to bypass the
attenuation circuitry enabling an
announcement at full volume
regardless of the volume setting,
including OFF.
