The utility frequency, (power) line frequency (American English) or mains frequency (British English) is the nominal frequency of the oscillations of alternating current (AC) in a wide area synchronous grid transmitted from a power station to the end-user.

95 dB @ 3,100 Hz tone are used in many current notification devices. [1] 80 dB @ 520 Hz tone are used in newer notification devices. [1] 70 dB to 100 dB weighted for human hearing (higher decibels, in the 100 to 115 dB range, were common with older electromechanical horns) [citation needed] Light (visible signals) 15 cd to 1,000 cd candela ...
