The word "alarm" started out as the exclamation "to arms!" coming from Italian all' arme! Such alarms, led to one of Shakespeare's choice stage directions "alarums and excursions", found in Henry VI and Richard III. The stage direction meant that all the extras dressed as soldiers were to dash about the stage shouting "To arms!" and generally giving the impression of exciting military action.
Plato and his students needed to be up in time for lessons, so the Greek genius built a vessel that gradually filled with water, forcing air through tiny openings that acted as whistles.
Before alarms clocks, there were candle clocks, that when burned, indicated the passage of periods of time. To set an alarm, you pushed a nail into the desired point and the nail would fall and clank on the metal holder.
Another one was a candle with a metal ball embedded in it. When the candle burned down, the ball fell out, hitting a hard surface and so waking up the sleeper.
During the Industrial Revolution, British workers were woken up by a person who made sure they could get to work on time. It was the job of the knocker-uppers to knock on people's doors or a long and light stick to reach windows on higher floors to wake them for the early shift.
