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) 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
Repeater Panels , Sounders Controller Units, etc.)
