Hold-open sys­tems in accor­dance with EN 1155

Though incon­spi­cuous during eve­r­yday use, they are indis­pensable when serious danger is pre­sent: elec­trical hold-open sys­tems are part of preventa­tive fire pro­tec­tion. Their task is to keep legally-pre­scribed fire barriers in escape and rescue routes open, especi­ally fire and smoke pro­tec­tion doors. They do this so effici­ently that many people pass through the door during eve­r­yday ope­ra­tions wit­hout noticing it. When fire breaks out on the other hand, an inte­g­rated smoke detector trig­gers the system and the door closes automati­cally thus preven­ting the spread of smoke gases and fire to adja­cent rooms and buildings.

App­li­ca­tion areas
Fire barriers in escape and rescue routes such as fire and smoke pro­tec­tion doors. These doors are normally used in kindergar­tens, hospi­tals, schools, hotels and residen­tial homes for the elderly. In addi­tion to fire pro­tec­tion, their pur­pose is to pro­vide barrier-free access to children, elderly per­sons and per­sons with disabili­ties. As a whole they the­re­fore ensure a smooth flow of public and goods traffic during daily ope­ra­tions.
