A structural fire suppression system is provided. The system incorporates the water supply and connects and accelerated pump system to the tank. The pump also communicates with a source of known fire suppression material to be mixed and subsequently distributed via conduits throughout either the duct work in a structure or behind the existing walls. The result is a short term fire suppression system which avoids disastrous effects in emergency.

Why it's free to use
- Filed June 9, 2003 and granted April 5, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 9, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 9, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
