scope:

Specifies requirements for door coordinator devices for double leaf swing doors fitted with door closers, and includes both separately mounted devices and mechanisms incorporated in door closers. Door coordinator devices are used where it is necessry to ensure the correct sequence of closing of double leaf swing doors. Example: Doors with rebated meeting stiles. Door coordinator devices manufactured to this standard are the only recommended means of providing 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.
