Can fire sprinklers go off accidentally? Yes, it has been known. Where there is a room with fully glazed walls and no ventilation then the room can get hot in the sun – it's rare. Records show that the chance of an accidental discharge from a fire sprinkler is in the region of 16 million to one.

(13-mm) thick plywood.” To summarize, in an NFPA 13R occupancy, CPVC can now be installed exposed up to 400 ft 2 and concealed without limit in ordinary hazards rooms. Guidance on how to properly CPVC piping systems exposed can be found in the manufacturers' installation instructions and technical manuals.

Fire Sprinklers are Simple, Reliable and Proven Heat from a fire will break a glass tube or melt a solder plug which releases the water. The water comes out as a spray that covers the area immediately around the sprinkler, putting out the fire. Only the one sprinkler closest to the fire opens.

Sprinkler systems contain either a glass bulb filled with a liquid that expands with heat, or a solder fusible link that will melt when it reaches a certain temperature. When hot air rises as the result of a fire, the glass bulb shatters or the solder melts, thus activating the sprinkler head.
