Abstract
A fire suppression system for an enclosed space, such as within a lavatory of a vehicle, includes a first inner gate, a second inner gate coupled to the first inner gate to define one or more air channels therethrough, and a temperature-responsive device coupled to one or both of the first inner gate or the second inner gate. The temperature-responsive device is configured to be in a first state below a predetermined temperature threshold, and a second state above the predetermined temperature threshold. In the second state, the second inner gate is moved relative to the first inner gate to close the one or more air channels.
Claims20
A fire suppression system, comprising:
- a first inner gate;
- a second inner gate coupled to the first inner gate to define one or more air channels therethrough;
- and
- a temperature-responsive device coupled to one or both of the first inner gate or the second inner gate,
- wherein the temperature-responsive device is configured to be in a first state below a predetermined temperature threshold, and a second state above the predetermined temperature threshold, and
- wherein in the second state, the second inner gate is moved relative to the first inner gate to close the one or more air channels.
A fire suppression method, comprising:
- maintaining a temperature-responsive device coupled to one or both of a first inner gate or a second inner gate in a first state below a predetermined temperature threshold;
- transitioning the temperature-response device to a second state above the predetermined temperature threshold;
- and
- in response to said transitioning, moving the second inner gate relative to the first inner gate to close one or more air channels defined through the first inner gate or the second inner gate when the temperature-responsive device is in the first state.
A vehicle comprising:
- an internal cabin;
- an enclosed space within the internal cabin, the enclosed space including a door having a grille and a fire suppression system coupled to the grille, the fire suppression system comprising:
- a first inner gate;
- a second inner gate coupled to the first inner gate to define one or more air channels therethrough;
- and
- a temperature-responsive device coupled to one or both of the first inner gate or the second inner gate,
- wherein the temperature-responsive device is configured to be in a first state below a predetermined temperature threshold, and a second state above the predetermined temperature threshold, and
- wherein in the second state, the second inner gate is moved relative to the first inner gate to close the one or more air channels.
