Abstract

A fire protection system for several zones of protection utilizes an expensive extinguishing agent and directs the extinguishing agent only to a zone in which a sensing device indicates the presence of a fire thus enabling the supply of the extinguishing agent to be delivered only to the fire zone and avoiding the necessity of charging the remainder of the system.
