Who invented the fire alarm?

The fire alarm was invented around 1066 during the battle of Hastings by a Mr. FU. Alarm. The creation of the fire alarm was a complete accident: Mr. Alarm was playing around with a buzzer, some smoke and a sensor. He then realized when he releases the smoke, the sensor picked it up, and the buzzer went off. Genius! Due to an unfortunate accident, he then perished (approximately two hours later) in a fire, though he had already shared his key idea with others, who would forget it completely. The fire alarm was then invented again in 1900 by some other guy. No one really cares about him, it's cool.  more
