Abstract
Abstract A fire protection system for an automated warehouse includes a roof mounted high-expansion foam generator and a high-expansion foam generator mounted on a stacker crane for movement therewith. Upon a sensing of a fire by a fire sensing means, a signal is sent to a central control means to indicate the presence and location of the fire. The control means then effects movement of the stacker crane to the location of the fire and initiates operation of the foam generator mounted on the stacker crane when it reaches the location of the fire. If the foam generator mounted in the stacker crane fails to extinguish the fire within a predetermined time interval, the central control means will effect actuation of the roof mounted foam generator to inundate the warehouse with foam to extinguish the fire. The stacker crane also includes a self-contained fire extinguishing system for extinguishing fire that might occur within the stacker crane.
