Abstract
According to some embodiments, a latch mechanism configured to be secured to a door is provided. The latch mechanism may include a latch bolt that is movable between a latched position and a retracted position, and the latch bolt may be configured to engage a corresponding door strike when in the latched position. The latch mechanism may also include one or more deployable pins configured to move to a deployed position in response to being exposed to a threshold temperature such that the deployable pins may retain the latch bolt in the latched position when the deployable pins are in the deployed position.
