Who invented the fire sprinkler?

In 1872, Philip W. Pratt patented the first fire sprinkler system. However, Henry S. Parmalee is widely credited with developing improvements on the original design. His improvements led to the development of the first practical automatic sprinkler head in 1874.  Parmalee was a piano maker from New Haven, Connecticut who was looking for ways to protect his factory.  His company, The Mathushek Piano Manufacturing Co, is recognized as the first building in the United States to be equipped with an automatic sprinkler system.

How do sprinklers work?

Fire sprinklers are the most visible part of a fire sprinkler system – an integrated array of pumps, piping and detection devices.  Pipes connect to your building’s water supply which is pushed, through pumping or pressurization, to upper floors in multi-level structures. Sprinkler heads are the distribution device that sprays water over a fire.  Sprinklers are activated by high heat, usually between 165-175ºF. When they sense temperatures in that range, they release water over the hot area, dousing the fire.

Why are fire sprinklers required in so many buildings?

So many municipalities require fire sprinklers because they are a proven way to limit death and extensive property damage.  The key to keeping a fire from reaching potentially dangerous and life-threatening proportions is early detection. Fire sprinklers operate automatically in locations where fires start. By releasing water directly to the source of the heat, fire sprinklers keep fires from growing out of control. One or two sprinkler activations can usually limit or contain an outbreak of fire.

Why can’t we just rely on the fire department?

Fire departments are an irreplaceable ally in fighting fires, but they depend on onsite alarms to notify them after a fire breaks out. By the time they arrive, fire could have spread and caused considerable damage.  With building fires, a bad situation can get worse more quickly than most people realize.  Fire sprinklers should be viewed as an effective first line defense or a “first response” system.

Do sprinklers ever activate accidentally?

It is extremely rare that sprinklers ever activate by accident. A sprinkler discharge without a fire event is usually the outcome of freezing or structural damage.
