Fire alarm

A fire alarm was an alarm system wired throughout a building which would alert people inside that there was a fire in the building. Fire alarms typically had two methods of activation — manual switches placed throughout the building which people could pull in case of a fire, and sensors which would detect heat or smoke and set off the alarm automatically.
