Electro-mechanical smoke exhaust skylights, as the name implies, automate the exhaust process. They are typically installed in building atriums or on the exterior walls of high-rise buildings, featuring an automatic mechanism for opening the smoke exhaust window.

In most cases, an electric smoke exhaust window is composed of several main components, including the sash, frame, and an automatic opening mechanism. This mechanism is further made up of an opener, an alarm, and an electric controller, among other components. It is designed to automatically open the smoke exhaust window upon detecting a significant amount of smoke caused by a fire, thus promptly expelling toxic smoke.
