https://en.wikipedia.org/wiki/War_of_the_currents#Safety_concerns https://en.wikipedia.org/wiki/War_of_the_currents#Safety_con... > The City of New York did not require burying and had little in the way of regulation so by the end of 1887 the mishmash of overhead wires for telephone, telegraph, fire and burglar alarm systems in Manhattan were now mixed with haphazardly strung AC lighting system wires carrying up to 6000 volts. So yes, even electrical fire and burglar alarms existed since 1880s. As a side-node, although "AC is dangerous" has been used as the corporate propaganda talking point during the Current War, the safety issue of AC (or mains electricity in general) was very real. Sometimes the AC wires would short to telephone, telegraph, fire and burglar alarms, and guess what could go wrong... The solution is proper safety practices and regulations in the next decade, rather than attacking and boycotting the use of AC.
