The standard provides details on product types, classification by use, test cycles, door mass, corrosion resistance. As well as definitions, product performance requirements, test apparatus, test methods and marking of products. In addition, the published standard includes annexes illustrating the various points made through diagrams and supplementary text. Complete editions of the standard can be obtained from Customer Services, BSI Standards, and Cheswick High Road, London W4 4AL.
No previous British Standard for these products existed; this is therefore a new standard.
Introduction
To ensure effective fire compartmentation in buildings, it is essential that the individual leaves of pairs of doors with rebated meeting stiles close in the correct sequence. This function is achieved by the use of door coordinator devices.
Examples of rebated meeting stiles
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 fire/smoke doors incorporating rebated meeting stiles.
Scope
This Furopean standard specifies requirements for separately mounted devices and mechanisms incorporated in door closers. There are additional requirements for devices for use on fire/smoke door assemblies.
A number of different types and designs are available as shown in the following illustrations.

Classification
This standard classifies door coordinators (selectors using a 6 digit coding system). This classification system applies to all building hardware product standards so that complementary items of hardware can be specified to, for instance, a common level of corrosion resistance category of use, etc. Each digit refers to a particular feature of the product measured against the standards performance requirements.
Digit 1 - Category of use
- only one category is identified:
- grade 3: for all internal and external doors for use by the public. and others, with little incentive to take care, is where there is some chance of misuse of the door.
Digit 2 - Number of test cycles
Two test durations are identified:
- grade 5:50000 test cycles: for all other door coordinator devices Figures 1 2 & 3.
- grade 8:500000 test cycles for door coordinator devices incorporated in, or for use in conjunction with, automatic swing door operators. and for devices incorporated in a door closer. Figures 4 & 5
Digit 3 - Test door mass
Five door mass grades and related coordinator sizes are identified according to table 1 of this European standard

Note: This table relates to doors with equal leaves only.
Where a door coordinator device is suitable for a range of door closer power sizes, both the minimum and maximum sizes shall be identified.
Digit 4 - Fire resistance
Two grades of fire resistance are identified for door coordinator devices manufactured to this European standard:
- grade 0: not suitable for use on fire/smoke door assemblies
- grade 1: suitable for use on fire/smoke door assemblies. Subject to satisfactory assessment of the contribution of the door coordinator device to the fire resistance of specified fire/smoke door assemblies. Such assessment is outside the scope of this European standard (see prEN 1634-1). Annex A indicates additional requirements for door coordinator devices.
Digit 5 � Safety
All door coordinator devices are required to satisfy the essential requirement of safety in use. Therefore, only grade 1 is identified.
Digit 6 - Corrosion resistance
Five grades of corrosion resistance are identified in accordance with prEN 1670.
- grade 0: no defined corrosion resistance
- grade 1: mild resistance
- grade 2: moderate resistance.
- grade 3: high resistance
- grade 4: very high resistance.
Example: the following marking denotes a door coordinator device suitable for a range of door closer power sizes from 4 to 6, for use on fire doors and with moderate resistance to corrosion.
Marking:
Each door coordinator device manufactured to this European standard shall be marked with the following:
(a) manufacturer抯 name or trademark, or other means of identification.
(b) product model identification.
(c) the six digit classification listed above.
(d) number of this European standard.
(e) year and week of manufacture.
Note: This information can be in coded form.
CE Marking
This standard has been prepared for use as a 'Harmonised Standard' to demonstrate conformity with the requirements of European Directives and, as such, it is intended that the products will, in due course, carry the CE Mark. Until this final decision is made, CE marking is not permitted. When used on fire doors these products have a critical safety function and it will, therefore, be necessary for manufacturers to operate a quality system such as ISO 9000.
Specification Issues
Door coordinators incorporated on a fire door assembly shall have satisfied the appropriate criteria of a fire test (currently BS 476: Pt. 22).
- A door coordinator shall not include a hold open device unless it is an electrically powered device in accordance with BS EN 1155.
- Door closers which incorporate integrated door coordinators shall conform to the requirements of BS EN 1154 including those additional requirements for door closing devices intended for use on fire/smoke door assemblies as indicated in the annex of BS EN 1154 covering those requirements where applicable.
- Manufacturer's advice should be sought it door leaves are unequal or if projection hinges are being used as variations in door geometry may affect the efficient operation of the coordinator.
Related Standards
As companion to BS EN 1158 two further product standards are now available. EN 1154 covers controlled door closing devices. EN 1155 covers electrically powered hold-open devices for swing doors.
Conformity
Conformity to the standard must be clearly and unequivocally stated. Such phrases as "tested to...." "designed to conform to...", "approved to...�, are not sufficient. To avoid misleading or confusing claims it is recommended that one of the following phrases is used when stating conformity:
a) this product has been successfully type-tested for conformity to all of the requirements. Test reports and/or certificates are available upon request.
b) This product has been successfully type-tested for conformity to all of the requirements including the additional requirements for latch action*/backcheck*/delayed closing*/ adjustable closing force*/fire/smoke door use*. Test reports and/or certificates are available upon request.
*Add as appropriate.
c) This product has been successfully type-tested for conformity to all of the requirements including the additional requirements for latch action*/backcheck*/delayed closing*/adjustable closing force*fire/smoke door use*. Regular audit testing is undertaken. Test reports and/or certificates are available upon request.
