System and method for extinguishing a fire

A system for extinguishing a fire, the system comprising:

• a source of a substance which is usable to extinguish a fire in a prescribed area;
• a control system which has (a) a first state in which the substance from the source is prevented from being released to the prescribed area and (b) a second state wherein the substance from the source is permitted to be released to the prescribed area to extinguish or control a fire at or adjacent to the prescribed area;
• an activation system comprising a first ignition element which ignites in response to exposure to at least one of (a) a flame, (b) heat above a predetermined temperature, and (c) a product of combustion,
• the control system changeable from the first state into the second state as an incident of the ignition element being ignited;
• and
• a second ignition element which is ignited as an incident of the first ignition element being ignited, the ignition of the second ignition element causing the control system to change from the first state into the second state.

• the control system changeable from the first state into the second state as an incident of the ignition element being ignited;
• and
• an operable system component in addition to the control system and having an operating state and a disabled state, a deactivation system, and a second ignition element which is ignited in response to ignition of the first ignition element to cause the deactivation system to change from a normal state into a deactivation state, the operable system component changing from the operating state into the disabled state as n incident of the deactivation system changing from the normal state into the deactivation state.

• an operable system component in addition to the control system and having an operating state and a disabled state, and a deactivation system, ignition of the first ignition element causing the deactivation system to change from a normal state into a deactivation state, the operable system component changing from the operating state into the disabled state as an incident of the deactivation system changing from the normal state into the deactivation state.

A method of extinguishing a fire in a prescribed area, the method comprising the steps of:

• situating a first ignition element in the vicinity of the prescribed area;
• in response to exposure of the first ignition element to at least one of (a) a flame, (b) heat above a predetermined temperature, and (c) a product of combustion, causing the first ignition element to ignite;
• in response to ignition of the first ignition element causing a control system to release a substance from a source of the substance to the prescribed area to extinguish or control a fire in the prescribed area;
• and
• changing an operable system component in addition to the control system from an operating state into a disabled state in response to ignition of the first ignition element.
