Burglar alarm history

HISTORY, THE BURGLAR ALARM SYSTEM

A bit Of history on Burglar Alarms

On June 21, 1853 the first electro magnetic burglar alarm patent was issued to Augustus Pope. It operated off of the use of a battery and was an individual unit for each window or door. The bell, which rang from an electric current streaming through a magnet causing it to vibrate, was mounted on top of the door frame into the wall. Wires ran from a spring "key" in the door/window through a circuit breaker near the bell, allowing the current to run constantly once the door/window tripped the spring. This electronic version of an alarm system is a great improvement on the previous bell systems where clock work and other devices were used to ring a bell less efficiently.

On October 11, 1853 in the same town of Somerville, not too longer after Augustus' patent, G.F. Milliken filed a patent for the improvement on this ground breaking electro-magnetic alarm. He designed the alarm device to reside in the room where the homeowner sleeps or is unaware of potential thieves forcing entry. As well, he runs the wires from all windows and doors, not just one. Each door/window has a spring with a certain amount of creases that signify a specific number of rings on the bell, alerting the homeowner of the precise doow/window where entry has occurred. These devices and improvements have lead to strength in home security technologies which can be trusted by all.

The electric burglar alarm patent was then purchased by a shopkeeper named Edwin Holmes in 1858, and Holmes set up a company to install and operate electric burglar alarm systems in Boston.

In 1859, Holmes moved to New York, where The Holmes Burglar Alarm Company grew and expanded into other cities. One burglar alarm system comprised of a number of contacts that were placed on windows, doors, safes, and other possible points of entery or interests of theives. If a contact were disrupted, then the electric current running through the wires connected to the alarm would cause it to sound off. The company has been successful so far, and is growing at a rapidly increasing rate due to the success of Holmes' current electric alarm.
