Smoke hatches are an integral part of the smoke and heat exhaust system. Through them, harmful to human health products such as smoke, CO2, heat, etc. are burned. They are mainly divided into facades and roofs. The facades are usually part of the glazing of the building and are clearly indistinguishable from the other windows. These types of smoke hatches can be opened in many different ways, such as opening the lower or upper axes, outwards or inwards. Even when designing the complete smoke and heat exhaust system (VSDT), the type and size of the smoke hatches are selected, taking into account the requirements of the European standard EN 12101. In this variant MY DOOR offers a solution with an automated GEZE system via electric actuators which open the smoke hatches in an accident. All of them are commanded by the entire system control center, again producing GEZE. The other option is to have roof domes.
