Abstract

Multistage thermal trigger devices disclosed herein may include a first stage and a second stage, wherein the first stage activates at a first temperature, and wherein the second stage activates at a second temperature. The first stage activates an arming assembly so that the second stage is armed. The second stage may then activate the output of the multistage thermal trigger device, via the arming assembly, when the second temperature is reached. An autoignition material (AIM) capsule is also disclosed herein. The AIM capsule may be deployed in connection with the disclosed multistage thermal trigger devices.
