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.
