The present invention relates to a fire detection sensor device easy to replace a sensor unit and, more particularly to, a fire detection sensor device comprising: a sensor for sensing ultraviolet light which generates a fire spark; a driving circuit for driving the sensor; and a discrimination circuit for determining outbreak of fire through a process of analyzing a signal sensed by the sensor. The fire detection sensor device comprises: a sensor device body including the discrimination circuit inside and attached to the ceiling or sidewall of the interior; and a sensor unit including the sensor and the driving circuit inside and detachable from the sensor device body in the exterior. In the fire detection sensor device according to the present invention, an existing integral expensive fire detection sensor device is provided with the sensor device body and the sensor unit which are physically separated from each other, and the sensor unit is configured to be easily detachable from the sensor device body. Therefore, it is possible to ensure the function of the fire detection sensor, provide a convenient maintenance of the installed sensor device, reduce maintenance time and costs, increase the convenience of management, and provide various designs, thereby further diversifying a user′s choice and improving product competitiveness. |
