Door Closers

The principal objective of a door closer is to close a door and in the case of unlatched fire doors in a corridor, to keep the doors closed in the event of a fire.

Most applications where the specification of a door closing device is mandatory, must use a product which conforms to the requirements of European Standard EN 1154 (or EN 1155 for electrically controlled units) and be CE marked accordingly.

EN1154

All forms of controlled door closing devices are covered by a harmonised European Standard, EN 1154. It provides details on product types and classifies products by use, test cycles, door mass, corrosion resistance and product performance requirements using a six digit classification code.

Closers which are controlled by an electromagnetic function must comply with the additional requirements of EN 1155.

Fire doors

Within EN 1154, certain recommendations are made for closing devices used on fire door assemblies. These include:

  • Closers size 1 and 2 are not considered suitable for use on fire doors.
  • Door closers shall not include a hold-open device unless it is an electrically powered device connected to the building fire alarm system.
  • Control regulators shall be either concealed or operable only by means of a tool.

Approved Document B of the UK Building Regulations states that, in the majority of cases, ‘a fire door should be fitted with a door closer which is capable of closing the door… from any angle and against any latch fitted’. In the European Union, CE marking is the most effective way to prove compliance with this requirement.
