Abstract (en)
A smoke alarm system utilises a conventional smoke detector (1) for producing audible alarm signals when the presence of smoke is detected. These signals are received by a mainsborne communication means (5) which may then produce further alarm signals or transmit electrical signals over a mainsborne communication system to activate remote alarm units.
