How to use:

The cover of the concealed fire sprinkler is welded to the thread with fusible metal, the melting point is 57 degrees. Therefore, in the event of a fire, when the temperature rises, the cover is first detached, and when the temperature rises to 68 degrees again (generally a sprinkler), the glass tube bursts and the water flows. Therefore, the most taboo of the concealed fire sprinkler head is that the cover is covered with paint and oil paint, which will cause malfunction.
