There are two main types of residential sprinkler systems: stand-alone and multi-use. Some systems can be designed to alert the local fire department in the case of activation, and others can tie into a home’s security system. An alarm bell installed on the outside of the house can alert neighbors to system activation if the homeowners are not present. Systems also typically include a flow alarm that sounds an alert when the system has been activated. Residential sprinkler heads come in a variety of designs that range from the commercial-looking metal spoke head to sleek, décor-friendly discs. One sprinkler is usually enough to provide coverage for an average size room. Other sprinkler heads might have a soldered link that melts at a certain temperature. Some feature a bulb filled with a special liquid that expands at a consistent rate when exposed to heat - at a designated temperature the bulb will break, activating the sprinkler head. The sprinkler heads used in residential fire sprinkler systems will vary by manufacturer, but most are heat activated. Photo: The Basics of Fire Sprinkler Systems
Fire sprinkler system design cost code#
In some states, residential sprinkler systems are now required by code in new construction and certain-sized remodels. “The sprinkler head will put out the fire before it grows,” says Marshall, “while the fire department may take 15 to 20 minutes to get there, and when they do they are dumping 250 gallons per minute and chopping holes in the roof to put out the fire.” Water damage from fire suppressed by a home sprinkler system incurs an average of $2,200 in costs water damage from a fire suppressed by a fire department adds up to an average of $45,000. “Eighty to ninety percent of fires are put out with one sprinkler head,” Marshall says. When activated, a sprinkler head will spray 15 to 20 gallons per minute. “This is what people think of, and it’s unfortunate.” In truth, occurrences of misfiring sprinkler heads are extremely rare (one manufacturer claims the chances to be 1 in 16 million), and systems are designed so only the sprinkler heads directly affected by the heat of a fire become activated, not the whole system.Ī residential sprinkler system will save a homeowner money in the event of a fire. “Hollywood movies show sprinklers going off everywhere,” says Roy Marshall, executive director of the Residential Fire Safety Institute (RFSI). The fear of a misfiring sprinkler head and the belief that a room fire activates the entire system are two such common misconceptions. The Case for Fire Sprinkler SystemsĬommon misconceptions about sprinkler systems (also called residential fire-protection systems and residential fire-suppression systems) prevent people from including one in their home. Despite the statistics, home fire sprinklers have yet to become code-mandated in new-home construction, and few homeowners who have the option choose to include this life-saving investment in their home. Easy installation is also, in part, due to the use of flexible high-pressure hose which do not need to go through the ceiling because of the position of the spray heads.Eighty percent of fire deaths occur in residences, with over 3,000 people dying per year in U.S.

It does not require a tank, and in the vast majority of installations does not require an upgrade to the water feed to supply its pump which draws only 5.6 litres per minute flow (standard domestic supply).
