A speaker system for a fire alarm is provided to reduce the cost for reinstallation by facilitating installation at an existing speaker system. A speaker system for a fire alarm includes a short prevention device. The short prevention device is composed of a case(30), a printed circuit board(40), a cable connector(50), a temperature fuse(60), and a case cover(70). The printed circuit board(40) is inserted into the case(30). The cable connector(50) is mounted to one side of the upper part of the printed circuit board(40) to be exposed outside the case(30), and is connected with the end portion of each cut cable. The temperature fuse(60) is mounted to the other side of the upper part of the printed circuit board(40), is connected with the printed circuit board(40) through a supporting bar(62), and is exposed outside the case(30) to be cut off when a temperature rises over a predetermined temperature. The case cover(70) is coupled to the lower end of the case(30). |
