HOW SPRINKLERS WORK

The typical sprinkler head consists of a plug held in place by a glass ampule filled with a glycerin-based liquid that expands when heated.
This liquid is designed to expand and break the tube at a certain temperature. The most common are designed to break at 155 degrees. In the average sized room, a 5mm diameter ampule will usually break in about one to one and a half minutes from contact with a heat source..
The plug is forced out by the pressurized water behind it and deflected away by a beveled edge. The water sprays over the deflector plate which is designed to distribute it in an even pattern. Water will continue to flow until the main valve is shut off.
Smoke and toxic gases rise from the source of the fire. They spread quickly along the ceiling and heat the air in the room.
The current of hot air forces a curtain of deadly gases down the walls, making escape more difficult. In a few minutes the air will become so hot that the entire contents of the room will ignite spontaneously. This is known as flashover and usually occurs between 1,000 and 1,500 degrees.
