In the event of fire, a SHEV removes smoke and hot gases from the building. This keeps escape and rescue routes free of smoke for longer, and the fire brigade finds better conditions.<\/p>\n\n\n<h2 class=\"wp-block-heading\">What does a SHEV consist of?<\/h2>\n\n\n<ul class=\"wp-block-list\"><li><strong>Triggering:<\/strong> smoke detector or SHEV push button (manual trigger)<\/li><li><strong>Control panel:<\/strong> evaluates the signals and supplies the actuators, often with emergency battery<\/li><li><strong>Window actuators:<\/strong> open the windows, rooflights or flaps<\/li><li><strong>Opening areas:<\/strong> the windows themselves, through which the smoke escapes<\/li><\/ul>\n\n\n<h2 class=\"wp-block-heading\">Natural and mechanical SHEV<\/h2>\n\n\n<p class=\"wp-block-paragraph\">With a <strong>natural SHEV<\/strong> smoke escapes by thermal buoyancy through opened windows or flaps. A <strong>mechanical SHEV<\/strong> extracts it with fans. Window actuators belong to natural SHEV.<\/p>\n\n\n<h2 class=\"wp-block-heading\">SHEV and daily ventilation<\/h2>\n\n\n<p class=\"wp-block-paragraph\">Many SHEV windows are also used for ventilation. The control must then separate both tasks: in the event of an alarm, the SHEV always has priority. More in the guide <a href=\"\/en\/rwa-and-daily-ventilation\/\">SHEV and daily ventilation<\/a>. Vent Systems supplies window actuators and ventilation controls, but no SHEV control panels.<\/p>\n\n\n<h2 class=\"wp-block-heading\">Read more<\/h2>\n\n\n<ul class=\"wp-block-list\"><li><a href=\"\/en\/what-is-an-rwa-system-abbreviation-function-and-design\/\">What is a SHEV system?
