Appl. No.:

12/080834

Inventors:

Mark Henry - Broken Arrow OK, US

International Classification:

G08B 17/10
F24F 7/06

US Classification:

454229, 340577

Abstract:

A battery operated smoke detection and smoke extraction system for use within a building with walls and ceilings. The system detects the presence of smoke, and provides means to contain fires within the area of origination. The system feeds positive airflow to a fire by extracting smoke into a dedicated ductwork system, whereby it is exhausted outside through the building envelope in a confined manner. The system decreases the possibility of fire back draft occurring. The system is comprised of a modified smoke detector, which activates a fan installed in a multi port manifold. Individual dedicated ducts, each serving individual rooms, are connected to the manifold. Each duct has a ceiling mounted back draft damper, for energy efficiency. The manifold is provided with a chimney and a decorative spark arrestor chimney termination. The system is powered by means of rechargeable batteries within a fireproofed recharging receptacle.
