경보기

마그누손 파크의 화재경보기.

경보기 또는 알람 디바이스(alarm device)는 음성, 시각, 또는 기타 유형의 알람 신호를 제공하여 누군가에게 긴급한 주의가 필요한 문제나 상황을 알려주는 기계이다.

'알람'이라는 용어는 "무기에"를 뜻하는 고프랑스어 a l'arme에서 비롯된 것으로, 적이 갑자기 나타나기 때문에 무기로 무장한 사람이 무기를 선택하고 행동을 취할 준비가 됨을 의미한다.[1]

역사

휘슬은 19세기에 경찰에 의해 사용되었다. 증기 휘슬은 선박, 공장 등에서 경보기로 사용되었다.

전기의 출현과 함께 다양한 유형의 경보기가 발명되었으며 예를 들면 버저, 경적, 사이렌, 호른 플래시, 색상광 등이 있다.
