The present invention relates to a self-standing fire alarm of a new structure which is easy to install since a separate power line is not necessary. The fire alarm according to the present invention comprises: a supporter (10) fixated on a building; and an alarm main body (20) which is detachably combined to the supporter (10). The alarm main body (20) comprises: a case (21); a sensing unit (22) to sense fire generation by being installed inside the case (21); a control unit (23) to be connected with the sensing unit (22) by being installed inside the case (21); an alarm unit (24) to be connected with the control unit (23) by being installed inside the case (21); and a battery to supply power to the sensing unit (22), the control unit (23), and the alarm unit (24) by being installed inside the case (21). Therefore the self-standing fire alarm according to the present invention is easy to install and can be installed regardless of an installation device, since the sensing unit (22), the control unit (23), and the alarm unit (24) are operated by a battery (25) as the power source, by removing the wiring construction process for connecting a separate power line. |
