Residential Fire Sprinkler Systems
Goal
• Provide entry level firefighters with an understanding of residential fire sprinkler system
• Provide entry level firefighters with an understanding of limitations of systems and how to respond when activated
• Discuss the advantages of home fire sprinklers in modern construction
• Develop a general understanding of public education related to home sprinklers
Modern Building Code
• The State of Michigan utilize the Michigan Residential Code 2009 edition.
• The State of Michigan removed mandatory requirements for home sprinklers, although most multi-family residences will require residential sprinkler protection
• National code documents require sprinkler protection and is debated heavily in many states with adoption
Why Home Sprinklers
• United States fire death is one of the highest for an industrialized nation
• Firefighter initiatives• Changes in Home Construction (light weight
construction, changing home environment)• Firefighter deaths• Communities such as Scottsdale and others in
the east coast
What is the role of the Firefighter
• Advocate• Knowledge on installation• Ability to respond to activated systems• Know when systems are in-service• Describe why systems are needed
Not all Systems are Created Alike
• Commercial systems vs residential systems• Different National Fire Protection Association
(NFPA) installation standards• Life Safety vs property conservation
Home Fire Sprinkler Systems
• Can be standalone or combination system with Home plumbing system
• Based on two sprinkler design (low flow)• Costs average $1.60 per square foot based on
recent studies• Sprinklers only installed in living spaces• Still has non protected spaces (floor and attic)
as well as small areas (small closets and bathrooms)
Riser is simple
Different sprinkler Styles
Design
• Piping and sprinkler layout per NFPA 13d• Pipe size is based on available pressure, height
of house and sprinkler type used• Most sprinklers discharge at a minimum psi of
7.0 and can discharge between 15-40 gallons per minute
• Design can vary based on sprinkler and construction type
Areas without municipal water
• Utilization of larger well or tank and pump system
• Water supply is for ten minutes of the design

Resources
• Installation costs by NFPA research foundation
Multi-Use Piping Option
Multi-Family Sprinkler Systems
• 4 Sprinkler Design• Based on NFPA 13R• Typically has a riser assembly and notification
device with flow switch• Sprinklers still omitted from non-living areas• Installed up to 4 stories in height and some
pedestal buildings
Multi-Family Systems
• Fire alarm supervision of riser assembly
• Spare sprinklers• Gauge• Typically PCVC piping
Design
• Per NFPA 13R• Sprinklers are typically
installed based on listing from 100 square feet up to 400 square feet per sprinkler
• Standalone riser• Typically includes a back
flow preventor
• FDC can be a one 2.5” connection
• Pipe size is based on height of structure, amount of friction loss and water supply available
Response
• Be aware of system limitations
• No sprinkler protection on attic and combustible space fires
Active Fire vs Activation
• What role does the responding firefighter have when responding to an active fire in a building equipped with residential sprinklers?
• A fire alarm is activated and the first unit arrives to find a broken sprinkler due to human error, what does the responding crew do?
Support of FDC
• System pressures may vary
• Pre-incident plan should identify FDC location
• What is operating pressure of the fire pump operator
Resources
• Built for Life• NFPA Fire Sprinkler Initiative• Michigan Fire Sprinkler Coalition
What can you do
• Encourage your department to conduct a side by side burn for your community
• Work with new developers for voluntary installation
• Include resources on your web-page• Post video links on facebook or twitter• Stay educated• Sprinkler your home!
