The cover of the concealed sprinkler is welded to the threads with fusible metal, and the melting point is 57 degrees. Therefore, in the event of a fire, the temperature rises and the cover falls off first. When the temperature rises to 68 degrees (general sprinkler head), the glass tube bursts and water spurts out.
