Abstract
A self contained fire extinguisher system that does not need external power in order to sense or initiate a release of a fire suppression medium, includes components configured to utilize a linear sensor network that can be connected to at least one and/or different sources of fire suppression mediums. A linear temperature sensing cord can be routed over a large area not practical with individual sensors. The cord can also actuate several and different sources of fire suppression mediums to maximize the suppression of a fire.
Claims20
A fire suppression system, comprising:
- a linear temperature sensor including a core disposed in a hollow casing, the core having a thermally sensitive pyrotechnic material with an auto-ignition temperature;
- and
- a source of a fire suppression medium coupled to the linear temperature sensor;
- wherein the linear temperature sensor is configured such that the thermally sensitive pyrotechnic material is ignited and combustion propagates through the core to the source of the fire suppression medium in response to an ambient temperature reaching the auto-ignition temperature.
A system for sensing an elevated temperature in a space, the system comprising:
- a linear temperature sensor disposed in the space, the linear temperature sensor including
- a hollow casing;
- and
- a core disposed in hollow casing, the core having a thermally sensitive pyrotechnic material with an auto-ignition temperature;
- wherein the thermally sensitive pyrotechnic material ignites and combustion propagates through the core in response to at least one portion of the space reaching the auto-ignition temperature.
A system devoid of electrical sensors for an elevated temperature, the system comprising:
- a linear temperature sensor including a thermally sensitive pyrotechnic material with an auto-ignition temperature;
- wherein the thermally sensitive pyrotechnic material ignites and combustion propagates through the linear temperature sensor in response to a portion of the linear temperature sensor reaching the auto-ignition temperature.
