System for dispensing flame retardant foam on exterior of a structure

A system for retarding flame initiating outside of a structure having at least one roof, wherein the structure includes a foam chemical storage container, the foam chemical storage container being in fluid communication with a roof plenum having at least one roof opening that enables distribution of flame retardant foam onto an outer surface of the roof;

• wherein the system further comprises:
• a foam distribution system comprising a foam expansion chamber in fluid communication with the first roof plenum for delivery of flame retardant foam from the foam expansion chamber through the at least one roof opening;
• a foam generation system comprising the foam chemical storage container in fluid communication with a foam solution storage container, and a water supply to the foam solution container;
• the foam generation system further comprising a system control module that controls a first compressed air line to the system control module and a first foam solution conduit from the foam solution storage container to the system control module to control air flow in a second compressed air line to provide a first compressed air flow and to control foam solution flow in a second foam solution conduit in response to an electrical control from an electrical control unit;
• wherein the electrical control unit is controlled by a communication line and a power supply line;
• and
• wherein the second foam solution and the second compressed air flow are combined and supplied to the foam expansion chamber.
