Residential Fire Sprinkler Systems

For more than a century, sprinkler systems have been used to protect our factories, office buildings, schools, and other commercial structures from the devastating effects of fire. But what about where fires are most common - in our homes? Until recent years, fire sprinklers in homes were relatively rare and limited primarily to high rise and high-density residences. 

Fire sprinklers, however, offer potential benefits for virtually every home. Fire sprinklers can save lives, reduce property loss and can even help cut homeowner insurance premiums. Home fire sprinklers can contain or even extinguish fires in less time than it would take the fire department to arrive at the scene. Combined with the use of smoke alarms, fire sprinklers also reduce the risk of dying in a home fire by 82 percent (as compared to having neither). 

The City of Fairfax Fire Department recognizes the effectiveness of fire sprinklers in saving lives and protecting property, and actively encourages homeowners to consider installing residential sprinkler systems. Using quick-response sprinklers and approved piping, homes can be built or even retrofitted to include low-cost automatic sprinkler systems connected to a domestic water supply. 

Some misconceptions about fire sprinklers:

  1. When one sprinkler goes off they all go off.
    Despite what you might see in movies or on television, sprinkler heads react independently to temperatures in each room. Thus, only the sprinkler closest to the fire will activate, spraying water directly on the fire. The rest of the sprinklers in the house will not activate unless there is also a fire in that location. 90% of all home fires are contained with a single sprinkler.

  2. If I burn something on the stove, the sprinklers could go off.
    Smoke alone cannot trigger sprinkler operation. Each sprinkler is individually activated by heat and will only go off in the event there is an actual fire.

  3. A sprinkler could accidentally go off causing severe water damage to my home.
    The likelihood that a sprinkler could discharge accidentally due to a manufacturing defect is extremely remote. Your home is much more likely to be damaged by leaks from ordinary household plumbing than from a residential sprinkler system.

  4. Water damage from a sprinkler system would be more extensive than the damage from the fire itself.
    Sprinklers severely limit a fire’s growth and use only a fraction of the water use by fire department hoses. Therefore, damage from a home fire sprinkler system will typically be much less severe than if a fire were extinguished using conventional firefighting techniques.

  5. Home fire sprinklers are too expensive.
    Nationally, on average, home fire sprinklers add only 1% to 1.5% to the total cost of new construction (about what you would pay for an upgrade in carpeting). Residential fire sprinkler systems may also be economically retrofitted to protect many older homes.

  6. Residential sprinklers are ugly.
    Modern residential sprinklers are inconspicuous, come in designer colors, and can be mounted flush with walls or ceilings.

  7. Installing a residential sprinkler system will not significantly affect my insurance premiums.
    Installing a residential sprinkler system will generally reduce costs for homeowner’s insurance because fire sprinklers will keep damage low. Discounts for homeowner’s insurance range between 5% and 15% and vary by insurance provider.

  8. I can’t install a residential fire sprinkler system because my home is not connected to a domestic water supply.
    Homes can be protected by fire sprinklers even in the most remote areas. Several manufacturers offer water tanks to supply residential fire sprinkler systems. The tanks are designed to fit in a garage or other storage area and can hold enough water to comply with national standards for home fire sprinkler systems.

A low-cost, reliable safety option, fire sprinklers can increase the value of your home, protect your family and possessions against loss from fire, and even decrease your insurance premiums.
