1. GENERAL INTRODUCTION

1.1 Introduction to the SM40 Surveillance Centre

In large public address distribution systems, which often play a key role in alarm and evacuation installations, it is vital that the correct functioning of the large number of ampliﬁers and loudspeakers used can be veriﬁed.

The SM40 Surveillance Centre is designed to monitor the status of ampliﬁers, loudspeakers, and cabling in large PA systems. Because it pinpoints any failures in the system, it saves a great deal of time, minimising repair costs as well as ensuring that the system is fully functional at the earliest possible moment.

On detection of a malfunction, error messages are generated automatically, giving the precise time and location of the fault. These messages can either be relayed to the system’s LCD display, or sent to an external printer for a permanent hard-copy record of the malfunctions. The messages can also be linked to warning lamps, buzzers, or personal paging units, alerting security and maintenance personnel. The possibility also exists to automatically switch in a spare ampliﬁer in place of an ampliﬁer which becomes faulty.

A pilot tone signal is generated which is inserted into the Test inputs of Philips SQ45 power ampliﬁer range. The Surveillance Centre is able to scan for the presence of this signal in up to 4096 monitoring devices, located in strategic places (at ampliﬁer outputs, loudspeaker cabling junction boxes, inside loudspeaker enclosures) throughout a PA distribution system. It can also receive ‘internal error’ information from an SM40 Routing System itself, as well as responding to external sensing devices such as smoke detectors and micro switches.

Being controlled by a microprocessor, the system is particularly ﬂexible, speciﬁc functions being easily programmed and changed to allow for alterations in the PA system conﬁguration and surveillance requirements.

Because the system is built around 19-inch rack mounted Euro Card circuit boards, expansion or alterations to the system are quickly and easily carried out.

A total Surveillance Centre would comprise:

- 19-inch rack unit, containing a microprocessor controlled SM40 Surveillance Centre

- 100V loudspeaker line, and low voltage loudspeaker, monitoring devices; external warning devices (lamps, buzzers, etc.)

- printer, or computer/printer combination.

All SM40 Surveillance Centre internal wiring is particularly installer friendly due to the ‘Quick Fit’ connectors used.

Standard twisted two core screened microphone cable is used to carry data and 15V power between the system and the interlinked Ampliﬁer/Loudspeaker Surveillance Boards.

All SM40 Surveillance Centres are built around the LBB 1370 Basic (starter) System, which is able to sequentially scan 8 Test Lines, each containing up to 128 monitoring devices; receive error input from 2 external sources, activates several relay error sets and synchronises the real-time clock.

The single 19-inch rack frame, capable of holding 9 circuit cards, has enough room to accomodate the Basic System plus 5 extra cards. Adding these cards expands the system, enabling it to feed more ampliﬁers with the Pilot Test Tone; scan a greater quantity of Test Lines and/or receives a larger amount of error inputs from external devices. However the system is limited by the number of Termination Boards installed.

When a system’s requirements exceed the space offered in a single rack frame, or extra termination boards are required the SM40 Extension Frame LBB 1360 is available. These frames can be linked together to expand the system.

2. UNPACKING AND INSTALLATION

2.1 SM40 Surveillance Centre - Unpacking and installation

In order to ensure that your SM40 Surveillance 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. The SM40

Surveillance Centre will operate successfully on mains voltages from 175 V to 264 V when tapped for 220 V, and from 90 V to 140 V when tapped for 110 V. Be sure to check that your system is wired for the correct mains voltage.

Caution: When tapping the system for the correct mains voltage, refer to the documentation supplied with the SM40 system.

NOTE: 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 Refering to Termination Board illustrations in chapter 10, wire the Test Lines, Ampliﬁer Test

Inputs, and Error Inputs/Outputs, to the screwblock connectors. If a printer or computer is to be used with the system, it should be wired to the RS232 serial interface socket at this time

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. SM 40 SURVEILLANCE BASIC SYSTEM

3.1 SM40 Surveillance Basic System LBB 1370

Self contained, fully operational system, around which all SM40 Surveillance Centres are built.

Comprises 4 circuit cards, mounted in a single 19-inch rack frame.

The Surveillance Basic (starter) System is the heart of the SM40 Surveillance 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 succesfully met.

Containing, in its single rack frame, the Display and Keyboard, and the Central Processor Card (CPC);

(along with its other circuit cards) the Basic System is a self contained, fully working unit in its own right.

Being supplied with one Surveillance Switch Card (SSC) the system is able to sequentially scan 8 seperate

test lines, each having upto 128 Ampliﬁer Surveillance Boards (ASB’s) and/or Loudspeaker Surveillance

Boards (LSB’s) connected.

The +15V required to power each test line in turn is provided by the in-built PE 1268/10 power

supply.unit.

The Basic System is also able to display error information generated by 2 external sources and clock

synchronisation using a single contact.

The communication PCB can send information generated by the CPC, via its RS232 port, to a printer or a

computer for the production of detailed hard copy of all monitored errors. The control relay card may be

used to activate external warning devices (lamps, buzzers, etc.) when an error occurs.

When a centre’s requirement exceed the facilities available in the Surveillance Basic System, further circuit

cards (plus the extension frames LBB 1360 necessary to accomodate them) are ordered, expanding the

system to meet speciﬁc application needs.

Because the Surveillance 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.

4. OPERATING AND PROGRAMMING THE SM40 SURVEILLANCE CENTRE

4.1 Central Processor Card - CPC

Eurocard 10 x 22 cm with an ‘a b’ connector (2 x 32). A microprocessor which can scan over 4000 monitoring devices, and activate more than 100 relays, via the communication line.

At the heart of the SM40 Surveillance Centre is the Central Processor Card (CPC). Capable of sequentially scanning 4096 monitoring devices; activating 64 SSC solid state relays, and 40 CRC relay sets; and sending error information to a display, external computer, or printer; this is a powerful piece of equipment. It provides a system of this type with a great amount of possibilities.

A Display & Keyboard mounted in the rack unit’s front panel, is used to display the scanning status and any detected errors, and also to carry out the user programming. When programming is complete the CPC returns to its normal scanning mode and, until a secret password is entered, the keyboard has no inﬂuence on the processor.

The basic functions of the Central Processor Card are as follows: SCANNING of Ampliﬁer Surveillance Boards (ASB’s) and/or Loudspeaker Surveillance Boards (LSB’s).

This is done by sequentially sending 15V power to each of the 8 Test Lines of the Surveillance Switch Cards (SSC’s) in turn, then sending communications data to each board in each line sequentially.

Translating the error data received from the ASB’s and LSB’s, along with external sensing devices, and relaying this information to the display, or via the RS232 port, to a printer or external computer.

ACTIVATING of relays, to switch on external warning devices (lamps, buzzers, paging units, etc.) via Control Relay Cards (CRC’s).

CHECKING of system hardware. The processor acts as a “watchdog”, continuously patrolling the SM40 Surveillance Centre hardware to check for errors, malfunctions or disconnections. If a problem exists, information, stating which card is faulty, is relayed to the display or printer.

An automatic restore function is also incorporated, so that when an internal error occurs, the system will not hang-up, and when an error is rectiﬁed no manual system reset is required.

REAL TIME CLOCK is built into the unit, and (in the program’s ‘Enable Print’ mode) is displayed on the LCD, giving date, hours and minutes. When an error occurs, the current time and date are transmitted to the printer. Synchronisation is via A17 on Surveillance Switch Cards No.1.

SERIAL INTERFACE. The standard RS232 serial interface connector mounted on a bracket on the frame, and wired to the CPC, allows the system to communicate with a wide variety of personal, mini, and mainframe computers as well as direct to serial printers. The communication has 8 data bits, and the baud-rate is selectable between 300, 1200, 2400, 4800 and 9600 baud. This, and the other I/O port parameters, such as number of Stop Bits, and Parity can be set in the installer programming menu.

SM40’s standard default parameters are: 2400 baud, 8 data bits, 1 stop bit, even parity.

A yellow LED, mounted on the front edge of the card indicates that the CPC is in communication with the rest of the SM40 Surveillance Centre, and 1 green LED indicates that adequate supply voltage is present.

The CPC has additional driver stages for the communication lines of 5 of the Extension Frames used to expand the Surveillance Basic System.
