The present invention relates to a fire alarm with a new structure which does not require a separate power cord and thus facilitates installation. According to the present invention, the fire alarm is powered by a battery (25), thus does not require a power cord, and thus has the advantage of being easy to install and not being restricted by the installation location. In particular, the fire alarm includes: a support (10) which is fixed to a ceiling surface (1) and has a concavely formed coupling part (11) on the lower side thereof, and an extension pipe (12) connected to one side thereof; an alarm main body (20) which is inserted into and coupled to the coupling part (11) of the support (10); and a winch (30) which is provided in the coupling part (11) and has a wire (32) which extends downward to be connected to the alarm main body (20) so that the alarm main body (20) is raised and lowered according to an operation of the winch (30). When the battery (25) depletes, the alarm main body (20) is lowered by the winch (30), thereby facilitating replacement of the battery (25).

    본 발명은 별도의 전원선이 필요 없어서 설치가 용이한 새로운 구조의 화재경보기에 관한 것이다. 본 발명에 따른 화재경보기는 배터리(25)에 의해 작동됨으로, 전원선이 불필요하며, 이에 따라, 설치가 용이하고 설치장소에 구애를 받지 않는 장점이 있다. 특히, 천정면(1)에 고정되며 하측면에는 결합부(11)가 오목하게 형성되고 일측에는 연장관(12)이 연결된 지지대(10)와, 상기 지지대(10)의 결합부(11)에 삽입 결합된 경보기본체(20)와, 상기 결합부(11)에 구비되며 하측으로 연장된 와이어(32)가 상기 경보기본체(20)에 연결되어 작동에 따라 상기 경보기본체(20)가 승강되도록 하는 윈치(30)로 구성되어, 배터리(25)의 수명이 다하면 윈치(30)에 의해 경보기본체(20)가 하강됨으로, 배터리(25)를 교환하는 것이 매우 용이한 장점이 있다.
