Stand-alone temperature response automatic fire alarm device

摘要

The present invention discloses a self-contained temperature response automatic fire alarm. The independent temperature response automatic fire alarm according to the disclosed invention is a starting to transmit an alarm sound output signal to a lower case and an upper cover coupled to form a housing, an alarm sound generator provided in the lower case, and an alarm sound generator The switch and the start switch operation lever are installed so as to be elastically biased downward on the upper cover to operate the start switch to operate the start switch by the rotation of the free end, and the static suppressed by pressing the free end of the start switch operation lever upward. It includes a heat-sensitive member that is set in a state detachably exposed to the lower case to support it in a constrained state, and when a fire occurs, the heat-sensitive member reacts at a certain ambient temperature and is damaged or deformed. Is released and descends by a downward elastic biasing force, and operating a start switch so that the alarm sound generator outputs an alarm sound. According to this configuration, the possibility of malfunction can be effectively lowered compared to existing sensors and digital operating mechanisms, so operation precision and reliability can be improved, and fire detection as a self-contained or independent product is possible because it is possible to exclude a separate wiring work dedicated to applying power. Monitoring is possible, increasing the degree of freedom of facilities for various places and locations, thereby securing the capability to significantly expand the range of fire detection and alarm areas.
