1 INTRODUCTION

The SM30 sound management system
provides an ideal solution for public address
distribution systems, requiring a compact
and flexible set-up with ease of operation.
Being controlled by a microprocessor, the
system is particularly flexible, specific
functions being easily made and changed by
non technical personnel. In order to meet
differing application needs a variety of
plug-in modules are available, and a wide
range of system configurations are possible.
The total public address distribution system
comprises:

■ One Control Centre, containing a

microprocessor and plug-in modules.

■ SM30 Call stations.

■ Power amplifiers which feed loudspeakers

located in geographical and/or functional
zones where people must be reached with
background music, announcements, pre­recorded messages, and alarm signals.

A maximum of 6 Call Stations may be used,
their functions being programmed from a
keyboard and display unit built into the
Control Centre. The system is designed to
handle calls and music simultaneously, so
that if a call is made to a particular zone or
combination of zones, music playing in
other zones will not be interrupted. A
system of priorities has been developed to
cope with conflict situations, for example a
person attempting to make a call when
another call is being made by someone with
a higher priority, the new call will not be
switched through.

Control Centre

At the heart of each SM30 system is the
Control Centre. This is a self contained
unit, housing the microprocessor which
controls SM30, and 12 slots which hold the

plug-in modules.
On the front panel of the Control Centre
are programming keys and associated LEDs,
an alpha-numeric LCD display, and keys for
controlling the functions of the music source
inputs. The programming keys enable the
installer to program SM30 to suit the overall
system configuration, and the user’s specific
needs. To allow the operator to control the
music sources, four Music Function Keys are
provided on the front panel.
These keys allow the operator to select the
music source; alter the music volume level
up or down; and mute the music signal.

Programming

The displays and the programming menus
are presented in the selected language. In the
normal ‘run’ mode of the system, the LCD
display indicates the name of the current
music source (e.g. “TUNER”, or “MUSIC
OFF”), plus the current music volume level.
In the ‘programming’ mode, the display will
enable the installer/user to see:

■ Program selections while scrolling

through the programming menus.

■ Function selections within a program.

■ The number of the current Call Station;

Function Key; Microphone; Control
Inputs; etc., being programmed.

■ Call priority status.

■ Attention or Alarm signal number.

■ Pre-recorded message number.

■ Loudspeaker Zone call; Control Relay;

and music routing.

■ Alternative Function Key functions.

■ Alternative Music Input text.

■ Current program status (e.g. CLEARING

MEMORY PLEASE WAIT).

■ ‘Error’ indications.

■ Language selection.

■ Alarm interruption.

■ Power-on delay.

SM30 plug-in modules

All of the interconnections between
individual modules in the Control Centre
take place automatically when they are
plugged into the interconnection board of
the Control Centre, so that no complex
inter-wiring is required. Owing to the
unique construction of the housing, the
modules slide in and out quickly and easily.
These features make SM30 simple and
inexpensive to install and maintain.
All switching and routing of the system is
carried out by software, so that hard-wiring
problems are kept to a minimum. This
means that though SM30 comprises a great
amount of features, making it a
comprehensive Public Address Centre, the
unit itself is uncluttered and simple to
assemble and use.

Call Station

The Call Station is the primary input to the
system, allowing the operator to route and
broadcast calls, announcements and music.
Each Call Station includes:

■ An electret condenser microphone.

■ A Numeric Keypad, allowing individual

selection of up to 18 loudspeaker zones
by typing in the zone number. Each Call
Station can be programmed with a
priority status, attention tone and pre­recorded message. These become
operational whenever the keypad is used
to route a call.

■ Zone Selection Indicator.

Each zone has its own LED which is
illuminated when the zone is selected.
When the call is completed the LEDs will
be extinguished.

■ 4 Function Keys.

Programmable with: priority; alarm and
attention tones; pre-recorded messages;
routing to loudspeaker zones; and
Control Relay activation.

■ Alternative functions.

These include music volume up/down;
music source selection; music mute; and
independent Control Relay switching or
toggling.

Using the Function Keys to make a call is
done in the same way as using the Key-pad.
The main difference being that instead of
the operator selecting the zones using the
Numeric Keypad, the Function Keys route
the call to a pre-programmed selection of
zones.
This of course saves a great amount of time
when an operator has to frequently call the
same selection of zones, or when an “ALL
CALL” must be made in emergencies.

Signal generator

Built into the SM30 Control Centre is a
signal generator, programmed with attention
tones and alarm signals. These can be
programmed, via the User Menu, to precede
a call or pre-recorded message, or to be
activated independently.

Background music

Background music sources, such as a
background music player, a radio tuner, a
compact disc player, a cassette deck, etc. are
connected and pre-adjusted.

Emergency Power Supply +48 VDC

In situations where the mains power supply
is unreliable, and SM30 is used for
security/evacuation purposes, an emergency
power supply may be used. This will be
switched on automatically whenever the
mains power fails.

2 SYSTEM OPERATION

SM30 Sound Management System presents
the operator with a logical, comprehensive,
and easy to use method of routing and
broadcasting calls, announcements, pre­recorded messages, and music.
SM30 is easy to use and logical in its
operation, but it is perhaps helpful to
understand, in principle, how the system
works.

A Typical Operation

Herewith a typical series of actions, initiated
by the person (“the operator”) making an
announcement, a paging call, etc., and
carried out by the system.

1 The operator selects in which loudspeaker

zones the call must be broadcast. This is
done by simply typing in the number of
each desired zone using the Numeric
Keypad of the Call Station. The Zone
Routing Indicator LEDs for these zones
will illuminate.

2 The microprocessor, which is continu-

ously monitoring the system, sees which
key is pressed. First it looks to see
whether another call is currently being
broadcast. If so, the processor activates a
flashing ‘BUSY’ LED on the call station.

3 When the ‘PRESS TO TALK’ key is

pressed, the processor checks which
priority rating each Call Station,
Function Key, microphone, etc., has been
given, and if the original caller has a
lower priority than the one being made,
its call will be muted and overridden by
the new caller. If the call being made has
the same, or a lower priority than the
original caller, the new call will be
ignored, and the ‘BUSY’ led will be
constantly illuminated to advise the
operator that the call has been aborted.

Pressing the ‘REDIAL’ key will automati­cally reselect the zones which were last
selected, eliminating the need to type
them in again.

4 If all is clear, the processor mutes any

music signal which may be broadcast in
the zone(s). Music routed to any other
zones will not be affected.

5 The processor checks which attention

tone has been programmed to precede an
announcement originating from the Call
Station, then it switches on the built-in
signal generator; selects a tone; and feeds
it out to the amplifier input.

6 If a message, recorded on the Recorded

Message Module, has been programmed
to precede a call, it will be broadcast after
the attention signal, and before the call.
Meanwhile the processor energises a
flashing green ‘WAIT/TALK’ LED in
order to tell the user that the call is going
through, but that they will have to wait
until the attention signal, or recorded
message, has finished.

7 The output signal of the amplifier is then

input into the SM30 Control Centre, via
its Zone Relay Module (a processor
controlled routing/switching matrix),
which routes it out again to the selected
loudspeaker zones.

8 When the announcement is completed

and the ‘PRESS TO TALK’ key is
released, the system returns to its idle
mode, with the processor continually
monitoring the system, until another call
is made. If music was playing in the
zone(s) it will return at its original
volume level.

Activation of Control Relays

Generating a call could also activate a relay,
or set of relays, which can be used to switch
on (or off) external equipment.

4

Volume Control Override Relays

It is important that announcements and/or
alarm signals come through at full volume,
regardless of the volume settings of
individual loudspeakers. The processor can
be programmed to switch in a series of relays
mounted on the Control Relay Card, which
correspond to the loudspeaker zones
selected. These in turn activate individual
volume control override relays in the
loudspeaker enclosures.

Using the Function Keys to Make a Call

Using the four Function Keys (mounted on
the Call Station) to make a call is done in
the same way as using the Keypad.
The main difference being that instead of
the operator selecting the zones using the
Numeric Keypad, the Function Keys route
the call to a pre-programmed selection of
zones.
This of course saves a great amount of time
when an operator has to frequently call the
same selection of zones, or when an “ALL
CALL” must be made in emergencies.
The Function Keys can also be used to select
and broadcast an alarm or attention tone, or
activate a pre-recorded message, without any
microphone generated call being made.
Whenever the function key is pressed its
Function Key LED illuminates, along with
any Zone Selection Indicators activated by
the routing of the Function Key. When the
call is completed the LEDs are extinguished.

Microphone and Control Input Calls

Calls, signals and/or pre-recorded messages,
can also be activated by means of a
microphone switch connected to the
Microphone Input Module, and a remote
switch wired to the Control Input Module
(The last of course without a “live” call).

Power on delay

In order to conserve power for battery
operated systems, the amplifier can be
switched on only when a call is made.
It causes a time delay (programmable from
2-9 seconds) between pressing an activation
key and the actual activation moment of the
call. Relay 3 of the Control Relay Module is
dedicated to switching the power to the
amplifier(s).

Alarm interrupt

In order to conform with certain European
military requirements an alarm call
generated by a contact on a Control Input
Module can be interrupted by a call with a
higher priority. After releasing the relevant
call key, the alarm signal will return for the
programmed duration. Selection of the non­interrupted or interrupted mode is
programmable in the “CTL ALARM
MODE” program of the Installer Mode.

3 ATTENTION AND ALARM

SIGNALS

Built into the SM30 Control Centre is a
signal generator, programmed with more
than 40 attention tones and alarm signals.
These can be programmed, via the User
Menu, to proceed a call or pre-recorded
message, or to be activated independently.
As noted in the list below, some of these
signals are terminated when the Call Station
key, Control Input Relay, etc. is released.
Other signals stop after about 1 minute, or
when the Call Station activation key is
pressed again. In order to confirm with
STANAG (Standard Nato Agreement)
requirements, an alarm signal can be
interrupted by a call with higher priority.
After releasing the call key, the alarm signal
will return for the programmed duration.
Along with the list below, chapter 6 (Call

5

Station) details the way in which each type
of call, when activated via the Call Station,
can be terminated.

Signal description

Signal numbers from 1 up to 12 are
attention or chime tones. The tone is quit as
soon as the activating key is released.
Signal numbers from 18 up to 50 are alarm
signals.
Alarm tones continue, even though the
activating key is released. An alarm tone
stops at the end of the signal duration or
after activating the relevant key again.
Signal numbers from 81 up to 87 are
identical to 1 up to 7.
These signals are meant for time signalling
purposes. However, they will always finish
their cycle, even if the activating key is
released.

4 CONTROL CENTRE LBB 1280

At the heart of each SM30 sound
management system is the Control Centre.
This is a self contained unit, housing the
microprocessor which controls SM30, and
12 slots which hold the plug-in modules.
On the front panel of the Control Centre
are programming keys and associated LEDs,
an alpha-numeric LCD display, and keys for
controlling the functions of the music source
inputs. The versatile construction allows the
Control Centre to be mounted free-standing
on a table top, or with other equipment, in a
19” rack. All of the interconnections
between individual modules take place
automatically when they are plugged into
the interconnection board of the Control
Centre, so that no complex inter wiring is
required. Thanks to the unique construction
of the housing, the modules slide in and out
quickly and easily. These features make
SM30 simple and inexpensive to install and
maintain. All switching and routing of the
system is carried out by software, so that
hardwiring problems are kept to a
minimum. This means that though SM30
comprises a great amount of features,
making it a comprehensive Public Address
Centre, the unit itself is uncluttered and
simple to assemble and use.

On delivery the rear panel of the SM30
Control Centre (fig.5.1) contains the Line
Output Module and the Power Supply
Module, as well as the removable blank
module panels. (The last only in LBB
1280/30). Both modules are essential
components, without which the SM30
system will not function.

Line Output Module

As its name implies, the Line Output
Module terminates line level audio signals
for the ‘Call’ output (fig.4.2D) and ‘Music’
output (fig.4.2A).
These feed the inputs of their respective
amplifiers. Both signals are terminated on 5­pole 180° DIN sockets, see fig.4.2 for wiring
details. For amplifier surveillance purposes,
it is possible to activate the built-in pilot
tone generator by means of a switch
(fig.4.2E) and to adjust the volume level
(fig.4.2F).
The module is fitted on the frontpanel with
two potentiometers; Alarm Volume Control
(fig.4.2C) and Attention Tone Volume
Control (fig.4.2B).
These allow the installer to set the output
volume of the internal signal generator to
the desired level for each of the two types of
signal tone.
The output volume level of the Call signal
has no preset (setting is done on both the
Microphone Input Module and the Call
Station Input Module).

Power Supply Module

This module contains the terminations for
both the mains power and emergency +48
VDC supply. The mains power socket
(fig.4.3A) is of the standard “Europlug”
type, and has a mains fuse holder built in.
To remove the mains fuse (fig.4.3B), first

remove the mains power cable (cord) from
the socket, and carefully insert a medium
sized screwdriver under the small lip of the
fuse cover (nearest the socket pins), and
gently twist the screwdriver to lever the fuse
holder out. A ‘Mate-N-Lok’ emergency
supply socket (fig.4.3D) is provided to allow
a +48 VDC supply to be connected.
An Earth terminal (fig.4.3C) is mounted on
the Power Supply Module to allow an extra
earth (ground) wire to be connected for use
with the Emergency Power Supply, or when
the mains power earth is inadequate.

5.2 Opening the housing

WARNING: Before attempting to open
the housing, the mains lead and the 48 V
DC battery plug should be disconnected.
It is not sufficient to merely switch off the
ON/OFF switch on the front panel.

Access to the inside of the Control Centre is
gained by removing the cover. This is done
by removing the four ‘cross-head’ screws
located in the sides of the unit. The cover is
then simply lifted off the housing. When the
cover is removed, a ‘retaining bar’ (fig.5.2A)
will be seen spanning the top of the housing.
This should now be removed by loosening
(not removing) the screws located in its
ends.
To access the screw heads, the screwdriver
must be inserted through the holes in the
sides of the housing (fig.5.2B). With the
screws loosened a little, the bar can be slid
vertically out of the screw slots.

Removing Module Blank Panels

The module blank panels are removed in a

similar way, by loosening the cross-head

screws a little and sliding the panels

vertically out of their keyhole slots.

Mounting the Modules

Before inserting the modules, read their

respective chapters to make sure that there

are no jumpers that need to be set in order

to carry out the desired function(s). The

modules are located, as illustrated in fig.5.1,

by aligning the front plate screw with the

keyhole slot (fig.5.2C); the key at the

bottom of the front plate (fig.5.2D) with the

slot in the bottom of the housing; and the

multi connector (fig.5.2E) with the socket

mounted on the mother board. The module

is then gently pushed into place by putting

pressure on the top of the circuit board. If it

does not slot easily into place do not

attempt to force it. Check that it is properly

aligned and try again. When the modules

are inserted, and properly seated in their

connectors, tighten their front plate screws.

The retaining bar (fig.5.2A) can now be
replaced by sliding it down in its slots as far
as possible, and tightening the screws in its
ends (fig.5.2B).

5.3 Voltage Setting

The system is delivered with the mains
transformer wired for 220 Volts AC.

Before attempting to switch on the unit
ensure that the voltage is set correctly for
your mains supply.

To change the voltage, unplug the long (grey
coloured) screw connector block (fig.

5.2X3), and rewire it for the appropriate
voltage, shown in the circuit diagram
(fig.5.3). Push the connector block firmly
back into place. The cover of the Control
Centre can now be replaced, and the screws
reinserted in the side panels.

48 Volt Emergency Power Supply

In situations where the mains power supply
is unreliable, and SM30 is used for
security/evacuation purposes, an emergency
power supply may be used. This can be
switched in automatically whenever the
mains power fails.

A 4-pole ‘Mate-N-Lok’ socket (fig.4.3D) is

provided on the Power Supply Module on

the back panel, to allow a +48 VDC supply

to be connected. The terminations for the

supply are clearly marked alongside the

Mate-N-Lok socket. The emergency supply

plug should be wired accordingly.

Earth Terminal (ground)

An Earth Terminal (fig.4.3C) is mounted on

the Power Supply Module to allow an extra

earth (ground) wire to be connected.

This should be used when the Emergency

Power Supply is used alone, or when the

mains power earth is inadequate.

If audible interference is present in the

system, caused by an inadequate, or

contaminated earth (e.g. due to heavy

equipment using the same common earth), a

separate “clean” earth may be connected to

the Earth Terminal.

scratched by metal components of SM30.
The SM30 Control Centre is available in

two versions:
LBB 1280/30 for table top use including the
cover.
LBB 1280/40 for 19” rack mounting,
without cover but including the mounting
brackets.

Removing Feet

WARNING: Before attempting to open
the housing, the mains lead and the 48 V
DC battery plug should be disconnected.
It is not sufficient to merely switch off the
ON/OFF switch on the front panel.

The feet of the Control Centre may be
removed for rack mounting if space is
limited. To remove the feet simply unscrew
the cross-headed screw which is recessed in
the centre of each foot.
If rack space is not limited however, it is
preferable to leave the feet in position and to
mount a narrow blank rack panel beneath
the unit. If the Control Centre then has to
be removed for servicing, the feet will
protect the surface of furniture from being

Calculating Required Rack Space

To simplify ordering of modular units and

panels to fit into standard 19” rack units,

Philips have chosen a standard height ‘HE’

equal to 44.55 mm (1.75 inches). Each

SM30 Control Centre, for instance, is 3 HE

high, requiring 133.65 mm of rack space.

The use of the HE unit eases the problem of

calculating the number of equipment

housings, blank panels, etc. that will fit into

a rack.

General Rules

Certain rules should be observed when

planning the equipment layout in a rack:

1 To ensure that the SM30 display is clearly

visible, and the controls are easy to
operate, the Control Centre should be
mounted at a height which makes it easily
accessible (head, or shoulder height if
possible).

2 Cassette front loaders, tuner scales, and

other frequently used equipment, should
be mounted at a height which makes
their front panels clearly visible to the
operator.

3 It is always preferable to mount power

amplifiers, which generate a certain
amount of heat, above heat sensitive
equipment, like SM30.If however, power
amplifiers must be mounted beneath the
Control Centre, a heat shield should be
installed above them. This is necessary to
deflect the hot air currents, which could
otherwise cause instability in the SM30
microprocessor controlled units.

5.5 Connecting amplifiers

The SM30 system is intended for use with 2
separate amplifiers, or two separate channels
of a multi channel amplifier. One channel
will handle the ‘call’ signal, and the other
channel will amplify the ‘music’ signal. This
allows the music signal to continue,
uninterrupted, when a call is made to other
loudspeaker zones. It is possible to use only
1 amplifier channel for both the ‘calls’ and
‘music’ signal. This has the disadvantage
however, that any music playing will be
interrupted whenever a call is made,
regardless of the zone(s) to which the call is
routed. Though the SM30 system will work
with any line level input amplifier, the
amplifiers from the Philips SQ45 range have
been specifically designed to take the greatest
advantage of the functions of SM30.

One Channel System (fig.5.5.2)

When using a single amplifier system, the

following steps must be taken:

1 The ‘Call’ and ‘Music’ outputs of the

Line Output Module should be
connected to their respective ‘Call’ and
‘Music’ inputs on the SQ45 amplifier.
The relay on the Line Output Module
will switch the active input of the SQ45
amplifier from music to call.
See the relevant SQ45 amplifier
Instructions For Use for details of this
function.

2 The output of the amplifier has to be

connected to the ‘Call’ input on the
‘Mate-N-Lok’ on the SM30 Zone Relay
Module.

3 Refer to Installer Program step 9 to

program this function.

As previously stated, zones with music will

be interrupted for as long as a call to any

other zone(s) lasts.

Rack Mounting

If the amplifier(s) and SM30 are mounted in

a rack unit, and an ‘earth loop’ occurs

(evident by a 50 or 60 Hz hum through the

loudspeakers) follow the Instructions For

Use given with the SQ45 amplifier for

details of earthing the units.
Two Channel System (fig.5.5.1)

Connections of SM30 to two amplifiers, or
two channels of a Philips SQ45 amplifier:
1 Connect both the ‘Call’ and ‘Music’

outputs of the Line Output Module, to
the separate ‘Call’ inputs of the SQ45
amplifier(s).

2 Connect the outputs of the amplifiers

(with two core loudspeaker cable) to their
respective ‘Call’ and ‘Music’ inputs on the
‘Mate-N-Lok’ connector on the Zone
Relay Module of the SM30.

6 CALL STATION

(CST) LBB 9568

Redial function (fig.6.1I)

Repeats the last zone selection.
The SM30 Call Station presents the

operator with a logical, comprehensive, and
easy to use method of routing and
broadcasting calls, announcements, and
music. Since each Call Station Input
Module will accept two Call Stations, SM30
will accept up to 6 Call Stations in total.

Electret condenser microphone

The high quality phantom powered
microphone with built-in bass rolloff filter
(fig.6.1L) gives clear voice reproduction,
even in difficult acoustic environments.

Built-in Compressor

Helps to keep the audio output level of the
Call Station constant, even in situations
where the operator’s speech volume level
changes radically. The amount of compres­sion is dependent on the Microphone pre­amplifier gain setting: the higher the gain
setting, the greater the amount of compres­sion, and therefore the greater the effect on
the microphone signal (see paragraph 6.3).

Balanced Line Level output

Allows Call Stations to be located up to
1000 metres from the Control Centre.

6.1 Operating controls
Numeric Keypad (fig.6.1J)

Allowing individual selection of up to 18
loudspeaker zones by typing in the zone
number. Each Call Station can be
programmed with a priority status, attention
tone and pre-recorded message. These
become operational whenever the keypad is
used to route a call. (See chapter 14 for
programming details).

Zone Selection Indicator (fig.6.1B)

Each zone has its own LED which is

illuminated when the zone is selected. When

the call is completed the LEDs will be

extinguished.

Function Keys (fig.6.1K)

The 4 function keys are to be programmed

with priority; alarm and attention tones;

pre-recorded messages; routing to loudspeak-

er zones; and Control Relay activation. The

alternative functions of these keys include:

music volume up/down; music source

selection; music mute; and independent

Control Relay switching or toggling (see

chapter 14 for programming details). Using

the Function Keys to make a call is done in

the same way as using the Keypad. The

main difference being that instead of the

operator selecting the zones using the

Numeric Keypad, the Function Keys route

the call to a pre-programmed selection of

zones. This of course saves a great amount of

time when an operator has to frequently call

the same selection of zones, or when an

“ALL CALL” must be made in emergencies.

Each Function Key may be programmed to

carry out a totally different task.

Key F1 can be programmed to route a low

priority call, preceded by an attention tone,

to several, frequently used, loudspeaker

zones.

Key F2 could be programmed to route an

alarm tone, followed by a pre-recorded

evacuation message, to all loudspeaker zones

(an “ALL CALL”).

Key F3 could be used to mute the music

signal.

Key F4 could be used to toggle a Control

Relay on and off, switching a warning lamp,

illuminated notice, etc..

18

NOTE: If a Function Key and the Keypad
are both selected to activate a call, the last
selection will always have precedence,
cancelling any other selection.

During Installer programming a program is
available to prevent the user of the Call
Station from addressing specific zones
selected via the keypad (see program

14.3.12).
Function Key LED (fig.6.1A)

Whenever a Function Key is pressed the
LED illuminates, together with any Zone
Selection Indicators activated by the routing
of the Function Key. When the call is
completed the LEDs will be extinguished.

‘Press-To-Talk’ Key (fig.6.1H)
Activates a call after the zones have been pre­selected using the Key Pad or Function Key.
The way in which a call is executed, and
how the ‘Press-To-Talk Key’ is used, depends
on the type of signal and/or message with
which the Key Pad, Function Key, or
Microphone is programmed.

■ Call without signal or message:

Will stop when the ‘Press-To-Talk’ Key is
released.

■ Call with attention signal and/or non-

repeating message:
Will stop when the ‘Press-To-Talk’ Key is
released.

■ Call with attention signal and repeating

pre-recorded message:
The message and/or signal cycle will
continue after the ‘Press-To-Talk’ Key is
released. The cycle can be stopped by
pressing the ‘Press-To-Talk’ Key a second
time.
If this is done during the attention signal,
the call stops immediately.
If the message is playing, the call will stop
at the end of the message.

■ Call with alarm signal:

The alarm signal will continue after
release of the ‘Press-To-Talk’ Key.
It can be stopped by pressing the ‘Press­To-Talk’ Key a second time.

Busy and wait/talk LEDs

(fig.6.1F and 6.1G)

Advise the operator whether a call may be

activated, the status of the call, and whether

any other calls are active.

The red ‘BUSY’ LED flashing means that

another call is in progress.

The red ‘BUSY’ LED illuminated constantly

indicates that the call has been blocked by

another call with a higher priority.

In its ‘WAIT’ state, the green LED flashes,

indicating that the call is accepted, and the

attention tone or pre-recorded message is

being broadcast.

The green LED illuminates constantly

(‘TALK’) when the tone or message finishes

and the processor switches on the

microphone for the call to proceed.

Loudspeaker Zone Template

A paper template is provided, on which the
names of the loudspeaker zones can be
written. The template has a detachable blank
section at the bottom, allowing it to be used
in a typewriter.
To mount the template in the Call Station,
first remove the right hand side cheek
(fig.6.1D), by unscrewing the two screws in
its side (fig.6.1E), and the one screw located
in the bottom. The plastic template cover
(fig.6.1C) can now be slid out. Place the
(type) written template in position over the
zone LEDs (having first torn off its blank
perforated panel), and carefully slide the
plastic template cover back in place.

Connection to Control Centre

Between the Call Station and the Call
Station Input Module (see chapter 7.1) the
following cabling is needed::

■ a shielded twisted pair for audio and

power transport;

■ a twisted pair for data transport.

When the copper diameter of each wire is
not less than 0.75 mm2 the length of the
cable can be up to 1000 meters for proper
functioning.

Microphone Preamplifier Gain Preset

should only be used for setting the

amount of compression, not for lining up

the Call Station output with the rest of

the SM30 System. See ‘Built-in

Compressor’ earlier in this chapter.

LED Intensity Preset

With the right hand side cheek removed, it

is possible to gain access to the LED

intensity preset.

To compensate for various local lighting

conditions, the illumination intensity of the

LEDs can be adjusted. Turning the

potentiometer (fig.6.2A) to the right

increases the intensity.

With the template and its cover in position,

and the microphone volume and LED

intensity adjusted, replace the right hand

side cheek.
