When someone goes to a theater, he or she often does not realize what is happening above and behind the stage. All set pieces, canvases, speakers and lamps ensure that a space is needed above the stage, which can be up to 30 meters high. Due to this height and the degree of filling of the room, it is not possible to create a reliable fire detection with conventional detection means.

Another problem is that theaters often work with stage smoke, which means that fire detection systems often generate unwanted reports. The fire detection system is often switched off during a stage performance, which then necessitates the deployment of an (expensive) fire watch.

Due to the active suction of Stratos aspirating systems and the possibility to adapt to the possible presence of stage smoke, a fast-acting system can be created that can continue to function during the performance.
