3. SM 40 SURVEILLANCE BASIC SYSTEM
3.1 SM40 Surveillance Basic System
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.
