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.a double pole isolating fuse rated at 2A. In each case you have to comply with local
regulations. ) 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".
Cable Segregation
All cables for the fire alarm system should be segregated from any other
cables/wiring/services.
