CTS
Central Emergency Lighting System
Control Unit (CU)
A liquid cristal display (80 characters on 2 lines), a
24-column printer and a keyboard interface theoperator
with the CU.
The display shows various selection menus to
make the operator’s control easier, as well as the
correct key to be pressed to start the various functions.
A keyswitch located at the back of the
keyboard can be used to prevent access by
unauthorised persons.
The CTS can be integrated into a centralised system
with a wider range of functions, or into a remote
control system via a telephone line. Two serial-line
connectors (RS232) are located at the back of the
CU and available also for the link between CU and
SCASE/SA Soccor Group .
A sealed, rechargeable battery provides for 3 hours
back up in case of a power failure
Self programming
The CU is able to check the start up system and
report the number of luminaires as well as the list of
corresponding identification code
Control Module (CM)
Using the CM, all units in a CTS system can be controlled
from a PC. Beghelli supplies the appropriate
software together with the CM.
Operation
The CTS working is based on the interactive communication
between the CU and each luminaire,
carried out in a sequencial operation manner
(polling). The CU microprocessor sends messages
on the data transmission line, recognised only by
the appropriate coded luminaire. The luminaire’s
microprocessor involved sends back a reply message,
which is then analised by the CU.
The CTS controls not only the status of the luminaires
but also the whole system. Any problems on
the data line or main power line are immediately
detected and a warning message is sent to the CU.
Operational test
The CU runs the operational test automatically or
on a specific command. The operator can use the
CU to program the time lag between two automatic
tests as well as the test timing.
During any test, the luminaire operates for about
one minute to verify the correct working of the
fluorescent tube.
The CU collects and stores any failure and reports
to the operator via display or a print out, stating test
day and time and also type of failure and identification
number of the luminaires involved. A yellow
light located on the front of the luminaire facilitates
identification of the defective unit.
Full duration test
Full duration test is run as the functionality test but,
because the state of the central battery is checked
by the CU, is longer collecting and storing any
possible failure.
Test results are shown on the display, and it is possible
to print out test date and time, type of failure
and identification number of the luminaires involved.
A yellow LED located on the front of the luminaire
facilitates identification of the defective unit.
The operator can program automatic testing
frequency between 1 and 99 weeks or can run
tests on demand.
