1. GENERAL INTRODUCTION AND OPERATING PRINCIPLES

1.1 Introduction

To meet the demand for a comprehensive public address distribution system, a new concept, built around 19 inch rack mounted Euro card circuit boards, has been developed.

Being controlled by a microprocessor, the system is particularly ﬂexible, speciﬁc functions being easily programmed and changed by non technical personnel. In order to meet differing application needs a variety of circuit cards are available and a wide range of system conﬁgurations are possible.

The total public address distribution system comprises: Call stations; a 19 inch rack unit, containing a microprocessor controlled SM40 centre; and SQ45 power ampliﬁers. These in turn feed loudspeakers located in geographical and/or functional zones where people must be reached with background music, announcements alarm signals and evacuation messages

The SM40 Distribution centre is fed by professional microphones mounted on Call Stations. Each Call station contains up to 10 user keys, which can be programmed to route the microphone calls, digitally stored messages, attention tones or alarm signals to one or several power ampliﬁers.

Because the SM4O centre is designed to handle many different commands simultaneously, a system of priorities has been developed to cope with conﬂict situations. A person attempting to call a zone already being called by someone with a higher priority will not be switched through, and is warned by a red (busy) LED mounted on the Call station. If the zone is clear to call, or is being called by a station with a lower priority, a green (talk) LED is illuminated and any lower priority calls are overridden.

All wiring in the SM40 system is particularly installer friendly. Two core screened microphone cable is used between call stations and central racks, and standard loudspeaker cable between power ampliﬁers and loudspeakers.

The basic (starter) system, LBB 1350, which can be fed by a maximum of 3 call stations, comprises: 1x Input Card; 1x Central Processing Card; the Display and Keyboard (which is mounted on the front panel); 1x Signal Generator Card; 1x Matrix Card; 1x Control Relay Card; 1x power supply; plus 1x Interconnection Board and 3x Termination Boards; tested and mounted in a 19 inch rack frame. The basic system is capable of controlling 8 ampliﬁers to feed a maximum of 8 loudspeaker zones.

The single 19 inch rack frame, capable of holding 10 circuit cards, has enough room to accommodate the basic system plus 5 extra cards. Adding these cards expands the basic system, enabling it to be fed by additional Call Stations and auxiliary inputs, and to feed more ampliﬁers.

When a system’s requirements exceed the space offered in a single rack frame, SM40 Extension Frame LBB 1360 is available. This comprises: 1x power supply; 1x Interconnection Board; and 5x Termination Boards; tested and mounted in a 19 inch rack frame. 10 SM40 circuit cards ﬁt into each Extension Frame, and these frames can be linked together to expand the system.

In a maximum conﬁguration, the distribution centre can accept (via a 16 x 64 matrix) up to 16 audio inputs to feed up to 64 individual ampliﬁer inputs, or (via a 32 x 32 matrix) up to 32 audio inputs to feed up to 32 ampliﬁers. The basic system is expandable to a maximum of:

■ 8 Input Cards,

■ 32 Matrix Cards,

■ 16 Control Relay Cards (128 make and break contacts).

■ 16 Digital Message Cards,

■ 8 Signal Generator Cards

Plus associated:

■ Tone Control Cards,

■ Automatic Volume Control Cards,

■ Signal Processing Cards.

Background music can be supplied by a background music player or from a radio tuner, compact disc player, cassette deck, etc..

The system, being capable of handling several different signals at the same time, is also ideally suited to situations where a number of music sources are fed to the same loudspeaker location simultaneously. Typical applications are hospitals, hotels and nursing homes, where it is required that a choice of music channels are selectable at each individual loudspeaker cabinet.

Various timer facilities allow tones, recorded messages, and music to be both switched in and routed at speciﬁc times of the day. Days of the week are also selectable.

An ambient noise dependent volume control function is available for installations where continually changing background noise levels are a problem (e.g. airports, sport stadiums).

As an optional extra, an I/O -PCB is available, which allows the SM40 system to be coupled to a personal computer via a standard RS232 serial interface. Depending on the software applied the computer can be used in the ‘active’ or ‘passive’ mode. In the passive mode you can read or record the static information (system conﬁguration, sources connected) and the ‘dynamic’ information (call logging, auxiliar y routing, failure information). In the ‘active’ mode you can use the computer for up/down loading of the programme, to program the matrix, or even to operate as a Call station or Master Call station.

Because of their integral music/announcement relays, SQ45 ampliﬁers are ideally matched to the SM40 centre. During an announcement the preset music level can be automatically overridden, while the announcement itself comes through at the normal level.

1.2 OPERATION PRINCIPLES

The SM40 Public Address Distribution Centre is easy to use and logical in its operation, it is helpful however to understand, in principle, how the system works.

Herewith a typical series of actions, initiated by the operator, and carried out by the system:

1. User Key on Call Station (CST) is pushed (see Chapter 5.12).

2. Central Processor Card (CPC), which is continuously scanning the system, monitors which User Key

on which CST is being pressed. It then puts into effect a list of orders it was given at its programming stage (see Chapter 4.1).

3. First it looks to see which ampliﬁer input, or inputs, our User Key is routed to (see Chapters 4.3.1, 5.3

and 5.12)

4. Then it makes sure that no other Call Station is currently calling that same input (see Chapter 5.12).

If the requested loudspeaker zone is already being called, the CPC checks which priority rating each User Key has been given, and if the original caller has a lower priority than the Key being pushed, its call will be muted and overridden by the new caller. If the Key being pushed has the same, or a lower priority than the original Key, its call will be ignored, and a ‘BUSY’ LED mounted on the Call station illuminates to advise that the call has not gone through.

5. If all is clear the CPC checks which attention tone and/or pre-recorded message has been programmed

to precede an announcement originating from our User Key, then it switches on the Signal Generator Card; selects a tone; activates message(s) from the Digital Message Card(s) (DMC’s) and feeds it to the designated ampliﬁer inputs (see Chapters 5.4 and 5.11).

6. Meanwhile it sends an electrical signal, via the IPC, back to the CST which energises a ﬂashing green

LED in order to tell the user that the call is going through, but that they will have to wait until the attention signal has ﬁnished (see Chapter 5.12).

7. If our key was given an alarm tone it will, dependent on the type of tone, be broadcast either for

1 minute, or until the user key is released.

8. The CPC checks, not only to see where the User Key has been routed to, but whether it has been

given any special orders regarding what it is to do when it gets there. Normally the CPC will mute any music signal being transmitted to a loudspeaker zone, when an announcement is being broadcast in it.

9. In order to allow the announcement and/or signal to come through at full volume, regardless of the

volume settings of ampliﬁers or individual loudspeakers, the CPC switches in a series of corresponding relays mounted on the Control Relay Card(CRC). These in turn activate the volume control override circuits of the SQ45 ampliﬁers and/or individual volume controls in loudspeakers, or loudspeaker groups (see Chapter 5.6).

10. When the CPC is certain that all is in order, it proceeds to give the message to the Input Card (IPC),

which in turn initiates the Call Station (CST) microphone.

11. The ampliﬁer built into the CST ampliﬁes the audio signal to line level, after which it runs through

the Input Card (IPC); via the Matrix Cards (MC)s; through Tone Control Cards (TCC)s if ﬁtted; via the Interconnection Board (IB); to the Termination Board (TB); and out to the inputs of the ampliﬁers; which in turn feed loudspeakers located in geographical or functional zones.

12. When the announcement is completed and the User Key is released, the system returns to its idle

mode, with the CPC continually scanning, until another call is made. This whole operation is carried out in less than

of a second, giving the user the speed and power necessary to communicate in a

clear and efﬁcient manner.

2. UNPACKING AND INSTALLATION

2-1

2.1 Unpacking and Installation

In order to ensure that your SM40 Centre functions properly, please follow these few simple instructions after unpacking your unit.

1. Carefully check the enclosed system components for physical damage caused during shipping. Any

complaints should be made immediately to the shipping company.

2. Mount the Basic System frame in the appropriate position in the 19 inch rack unit (not higher than

shoulder height, so that the display and keyboard can be clearly seen).

3. Extension Frames are available to expand the Basic System into a larger system. These should now be

mounted, and wired according to the appropriate wiring diagrams.

4. Mount the ampliﬁers and auxiliary equipment in the rack(s). If power ampliﬁers are mounted beneath

SM40 frames, a heat shield should be installed above them to deﬂect hot air currents.

5. Taking care to avoid earth (ground) loops, wire the mains power to the units.

SM40 will operate successfully on mains voltages from 187 V to 264 V when tapped for 220 V, and from 90 to 132 V when tapped for 110 V. Be sure to check that your system is wired for the correct mains voltage. Refer to Chapter 2.2 Power Supply Modules.

Warning: Because it is possible to touch the mains voltage terminals when the frame back panels are opened, it is advisable not to turn the power on at this stage.

6. Open the back panel of the Basic system, and check that all of the connectors on the Interconnection

Board and Termination boards are ﬁrmly in place. If, in the unlikely event that one of the connectors has become disconnected, refer to the enclosed basic system wiring diagram.

7. Referring to Termination Board illustrations in Chapter 5.2, wire the Call Stations, auxiliary input

sources, ampliﬁers, etc., to the screwblock connectors.

8. Plug the screwblock connectors into the termination boards, ensuring that they are in the correct

locations.

9. Open the front panel of the rack frame and gently push each of the circuit cards to make sure that

they are all ﬁrmly connected to the Interconnection Board.

10. If, after double checking that all of the mains power and signal wiring is correct, and that the system is

adequately earthed, switch on the mains power to the rack.

3.1 Basic System - BS LBB 1350/30

Self contained, fully operational system, around which all SM40 systems are built. Comprises 5 circuit cards, mounted in a single 19 inch rack frame.

The Basic (starter) System is the heart of the SM40 Public Address Distribution Centre. When supplemented with a variety of Euro-cards and PCB’s, a wide range of system conﬁgurations are possible, and many different application needs are successfully met.

Containing (along with its other circuit cards) the Central Processor Card (CPC); and the Display and Keyboard; and because it is mounted in a single rack frame; the Basic System is a self contained, fully working unit in its own right.

Being fed by a maximum of 3 Call Stations LBB 9567 (ordered separately), it is capable of controlling 8 ampliﬁers to feed a maximum of 8 loudspeaker zones.

Because the Basic System is supplied fully wired, adjusted, tested, and mounted in its own 19 inch rack unit, ready for use, it is an ideal model from which to build a larger system.

By running through the Basic System’s programming sequence it is easy to understand how the SM40 concept works. Any larger system has merely a greater quantity of Call Stations (CST)s, auxiliary inputs, etc. to program, and is dealt with in exactly the same way.

When a system’s requirements exceed the facilities available in the Basic System, further circuit cards (plus the Extension Frames LBB 1360 necessary to accommodate them) are ordered, expanding the system to meet speciﬁc application needs.

4.1 Central Processor Card - CPC

At the heart of the SM40 Public address Distribution System is the Central Processor Card (CPC). Capable of controlling 16 or 32 call stations; 320 user keys; 1024 matrix points; 2 x 128 relays, 16 Digital Message Cards and 8 signal generators; this is a powerful piece of equipment, providing a system of this type with previously unheard of possibilities.

The basic functions of this card are as follows: DETECTION of call station user keys. Using information given it by the Input Card (IPC), the unit is

capable of sensing which user key is being pressed. ROUTING of microphones and attention signal tones (actuated by user keys), alarm tones, digital

messages, background music, etc., via Matrix Card (MC) to ampliﬁers and loudspeakers located in geographical and/or functional zones.

USER KEY PRIORITY level setting. To cope with conﬂict situations (e.g. when 2 call stations attempt to call the same zones simultaneously) each user key is given a priority level of 0-9, 9 being highest priority.

ATTENTION SIGNAL TONES, are coupled with the user keys so that when a key is pressed the tone will be broadcast before or instead of an announcement. Dependant on their character these tones may also be used as alarm signals or test tones.

DIGITAL MESSAGE CARD control, allows per card up to 7 messages with varying duration up to a maximum of 65 seconds to be recorded, and played back as desired. The maximum number of cards per centre is 16.

SWITCHING of loudspeaker volume control override circuits, and bypassing of the input attenuators in the SQ45 ampliﬁers, via the Control Relay Card (CRC). SWITCHING of ampliﬁer outputs for loudspeaker group switching, via ‘unlocked’ Control Relay Cards.

CHECKING of system hardware. The processor acts as a “watchdog”, continuously scanning the SM40 system hardware to check for errors, malfunctions or disconnections. If a problem exists a message is displayed on the lcd screen of the Display & Keyboard; for instance if Call Station 3 is disconnected the message displayed is:

REAL TIME CLOCK is built into the unit, and is displayed, giving date, hours and minutes. A timer facility is coupled to the clock, making it possible to switch on and route tones, recorded messages and music at speciﬁc times of the day, or week.

A yellow LED, mounted on the front edge of the (CPC) card advises that the unit is running with the rest of the SM40 system, and 1 green LED indicates that adequate supply voltage is present.

A Display & Keyboard mounted on the rack unit’s front panel, is used to carry out installer and user programming as listed above. When programming is complete, the unit returns to its idle mode and, until a secret password is entered it has no inﬂuence on the processor. In this state the day, date, and time are displayed.

The CPC has 2 driver stages providing communication lines for up to 80 cards approximately. All circuit cards controlled by the CPC must be mounted as close as possible to the CPC. All other cards may then be mounted in as many frames as are necessary.

SM40 KEY FUNCTIONS

0-9 Numeric keys to select call station number,

user key number, priority level, attention signal tone number and program numbers as listed in the main menu.

Moves the cursor 1 position to the right when routing Call Stations, Attention Tones, pre-recorded messages or Auxiliary sources (background music players, etc.) to ampliﬁer inputs; each ampliﬁer input representing a loudspeaker zone. Also used for programming free-programmable relays. This is called : “MATRIX/RELAY PROGRAMMING”.

Moves the cursor 1 position to the left during matrix/relay programming.

Moves the cursor to the beginning of the following lock of 8 ampliﬁer inputs during matrix programming.

Moves the cursor to the end of the previous block of 8 ampliﬁer inputs during matrix programming.

Switches the output, indicated by the cursor during matrix programming, to the “ON” position. Routing the call station or auxiliary source being programmed to the desired ampliﬁer input.

Switches the output to the “OFF” position, cancelling routing of the call station or auxiliary to the ampliﬁer input indicated by the cursor.

Switches all outputs to the “ON” position, routing the source being programmed to all ampliﬁer inputs.

Switches all outputs to the “OFF” position, cancelling all routing of the source being programmed.

Mute Switches the output, indicated by the cursor,

to the -10 dB mode when it is desired to attenuate the volume of background music during an announcement, rather than muting it. This function is only available on ever y fourth input of the Matrix card.

Break If pressed during auxiliary programming, will

return user to the main menu for the next programming sequence (in this case Call Station programming) without storing any new information. During Call Station programming, ‘BREAK’ returns the user to the previous stage in the program (e.g. after “PROGRAM USER KEY: (1-10)”, it will go back to “PROGRAM CALL STATION: (1-16)” without storing any new information.

Enter Enters numerical inputs into the memory and

moves to the next program stage, or at the end of a program sequence; to the main menu ready for the next program.

A While the system is in its run mode, pressing

button A, displays the system status. The top line of the display indicates where Call Stations, Signal Generator Cards, Digital Message Cards and auxiliary sources are connected to the matrix. The bottom line indicates which user key is currently being pushed, and which SGC is producing a signal or which DMC is relaying a message.

B In the Installer programming Menu, button B,

is used to set the I/O RS232 serial interface communication parameters with an external computer. The parameters are as follows: Baud rate, stop bits and parity. See Chapter 5.13 on the I/O PCB.

C With the system in programming mode,

button C is used to couple or uncouple the Keysets (KST)s, as described in the Input Card, see Chapter 5.3.

Result / Remarks

When an audio output of SM40 is activated by a call, the corresponding relay of the Locked Relay Card, with address 1-4 is also automatically activated. If a system has no more than 8 audio outputs, CRC cards 2, 3 and 4 can be considered as being freely programmable. However they are still shown on the display as routing. They can be used to activate zone relays or volume override relays.

In the 32x32 matrix mode, the relays of Locked Relay Cards L5-L8 are free and can be considered as free programmable and can be programmed accordingly.

[L-5] [L-6] [L-7] [L-8]

This is the current programming of the relays on Locked Relay Cards 5-8. This causes the programmed relays to activate when the corresponding Call Station key is active. In addition the relays on Unlocked CRC U-4, U-5, U-6, U-7 and U-8 can be activated via a user-key.
