Abstract
A heat-activated fire-suppression system is provided. The system can include one or modules installed in an exterior panel of a building. The one or more modules can include a shape memory alloy wire that deforms upon heating to cause the module to release a pressurized substance. The system can include an alarm module that emits an auditory alarm. The system can include a fire-suppression module that releases a fire-suppressing substance upon the shape memory wire deforming in response to heating.
Claims7
A module for a heat-activated alarm system, the module comprising:
- a sound emitter;
- a power circuit configured to connect the sound emitter to a source of electrical power;
- an insulator disposed at least partially within the power circuit when the module is in an armed configuration such that the insulator interrupts the power circuit;
- and
- a shape memory alloy wire configured to connect the power circuit to provide electrical power to the sound emitter by at least partially removing the insulator from the power circuit upon a heating of the shape memory alloy wire to a deformation temperature,
- wherein a first end of the shape memory alloy wire is fixed relative to the module,
- wherein a second end of the shape memory alloy wire opposite the first end is mechanically connected to the insulator, and
- wherein the heating of the shape memory alloy wire to the deformation temperature causes a length of the shape memory alloy wire to decrease such that the insulator is pulled away from the power circuit.
