ÖNORM EN 1158

This European Standard specifies requirements for the following door coordinator devices for use on double leaf swing doors: separately mounted door coordinator devices; coordinator mechanisms incorporated in door closers; coordinator mechanisms incorporated in door closers with electrically powered hold-open devices. Door coordinator devices manufactured in accordance with this European Standard are recommended for use wherever there is a requirement for reliable sequential closing of double leaf swing fire/smoke doors incorporating rebated meeting stiles. Door coordinator devices for use on fire/smoke doors need additional attributes in order to contribute actively to meeting the essential requirements of safety in case of fire, either independently or as part of a complete door assembly. These additional requirements for door coordinator devices for use on a fire/smoke door assembly are specified in normative annex A. Door closing devices are covered by EN 1154. Electrically powered hold-open devices are covered by EN 1155.
