Abstract
An automatic fire extinguishing system acting through aerated foam filling of the room on fire. The automatic fire extinguishing system includes an air conditioning system comprising a central blower with air feeding ducts having an air inlet in each room, an air outlet in each room communicating with an exhaust duct, a screen occupying the section of each of the air inlets, a foaming mixture generator for spraying the screen with foaming mixture arranged near the air inlet and at least a fire detector in each room, the fire detector controls the foaming mixture generator of the room.
Claims9
In a fire extinguishing system for multicompartmented buildings said system comprising:
- the combination of a trunk-line duct system having an upstream inlet and a plurality of downstream branch duct outlets, at least one of said duct outlets being in each compartment to be protected, an air conditioning system having an outlet connected to said duct system inlet for providing an air stream in said duct system, a high expansion foam plug generator located adjacent at least one branch duct outlet for each compartment to be protected and control means associated with each of said compartments to be protected for simultaneously energizing said air conditioning system and said foam plug generator in response to the presence of a fire in said compartment.
An automatic fire extinguishing system for a building having a plurality of rooms, a central air blower, an air ducts for feeding air from said blower to an air inlet in each room, an air outlet in each room communicating with an exhaust duct, a screen covering each said air inlet, a foaming mixture generator individual to each said screen for spraying on its associated screen a foaming liquid mixture, a fire detector in each said room, said fire detector actuating only the said associated foaming mixture generator upon detection of a fire in the associated said room, and a variable speed motor for driving said blower, said motor having high speed and low speed, said motor operating at low speed in the absence of a fire, each said fire detector actuating said motor to operate at said high speed.
