Abstract
An apparatus for controlling smoke in the event of a fire. The apparatus has a manual release arm pivotally secured to a base surface and a spring with one end attached to the base surface and the other end connected to the manual release arm. A releasing arm is pivotally connected to the base surface, and a fire linkage is pivotally secured to the base surface and releasably engages the releasing arm and the manual release arm. A bar under tension releasably engages the releasing arm such that when the releasing arm pivots and releases the bar, the bar travels away from the releasing arm due to the tension. A method for controlling smoke, or like, in the event of a fire.
