SICLI COP3000, Installation Manual, Page: 24 / 45

External Connections (Mains Supply)
The mains supply should be installed in accordance with the current edition of the IEE
wiring regulations. Connection to the mains supply must be via an isolating device (e.g.
an isolating fuse rated at 3Amps maximum) reserved solely for the fire alarm system.
The cover should be coloured red and labelled “FIRE ALARM - DO NOT SWITCH OFF”.
The isolating protective device should be secure from unauthorised operation and
ideally installed in a securely closed box with a breakable cover.
An additional warning label should be provided, depending on whether:-
a) The isolating protective device is fed from the live side of the main isolating
device in which case the label on the isolating protective device, should read
in addition - “WARNING: THIS SUPPLY REMAINS ALIVE WHEN THE MAIN
SWITCH IS TURNED OFF”. A further label should be placed on the main
isolating device reading “WARNING: THE FIRE ALARM SUPPLY REMAINS
LIVE WHEN THIS SWITCH IS TURNED OFF.
Or
b) If the isolating protective device is fed from the dead side of the main
isolating device, a label should be fixed to the main isolating device reading
“WARNING: THIS SWITCH ALSO CONTROLS THE SUPPLY TO THE FIRE
ALARM SYSTEM”.
Distributed Power Supplies
The above also applies to any distributed power supply (i.e. mains connections for
COP3000/PR repeat units CSC354/O relay units, etc.)
Cable Segregation
All cables for the fire alarm system should be segregated from any other
cables/wiring/services.
Wiring configurations
Spurs can be taken off the loop in the following ways:
1) CZMU352/O Addressable Interface - Allows up to 20 conventional smoke detectors
and unlimited Cooper conventinal call points.
2) Direct Loop Spur Wiring - Allows a zone of analogue
sensors and callpoints to be directly spurred off the loop
NOTE: The mains cable tail ends must be insulated
to prevent dangerous conditions arising in the event
of accidental switching on of the mains supply.
