Doors with horizontal operating rod

The EN 1125 standard describes panic door locks with a horizontal operating rod for doors in escape routes .

General

Fittings on doors of escape and rescue routes should ensure easy opening in an emergency, regardless of whether the doors are e.g. B. locked by locking or are only locked into the strike plate by means of a lock latch for fire or smoke protection reasons. For example, if a door has been locked from the outside, it has to be opened at any time from the inside in the direction of escape with just a simple hand movement.

The EN 1125 is of particular relevance, as it basically represents the optimum for escape and rescue route fittings, since the locked door is opened by simply applying pressure to the door fitting (panic bar). If fittings according to EN 1125 are used, panic is almost impossible. No other guidelines on the design of the hardware then have to be taken into account. When using the other hardware standard EN 179, a hazard or risk assessment must be carried out to determine whether it can be used.

EN 1125 describes fittings that are operated with a handle bar running horizontally across the door leaf and located between two swivel levers or a push bar. The locking mechanism used, such as the lock, is part of the fitting. The condition is that the swing door leaf opens in the direction of escape.

EN 179 also defines systems for such door locks, where a knowledge u. a. the location is given. EN 13637 defines electrical interlocks that still allow escape

Further standards for doors in escape routes

EN 179 (fittings with lever handles or similar)

The EN 179 describes fittings, with a door handle ( door handle to be actuated), a door handle like a pivot lever executed or a cleat. The locking mechanism used, such as the lock, is part of the fitting. These fittings can only be used where other conditions ensure that panic cannot occur.

EN 13637 (electrical locking of doors)

Instead of the originally planned 2 standards (EN 13633 and 13637) for electrical locking of doors in escape routes, the common EN 13637 has been in effect since 2015. In principle, several types or applications are possible:

  1. The door is only electrically locked by a fitting in accordance with EN 13637.
  2. The door has an emergency exit lock according to EN 179 and either this lock is electrically locked or (which is the rule) the door is electrically locked independently of the lock.
  3. The door has a panic door lock according to EN 1125 and either this lock is locked or the door is electrically locked independently of this.

Basically all interlocks according to EN 13637 work according to the closed-circuit current principle, i.e. H. in the event of a power interruption (intentional) or a power failure (unintentional), the electrical lock is immediately omitted and the escape door can be opened. A system according to EN 13637 consists of at least the following elements (individually or in combination):

  • Release element for releasing the electrical lock (emergency button)
  • Electric lock to secure the escape door (electric escape door opener or electric holding magnet or locking of the lock according to EN 179 or EN 1125)
  • electrical control for supply, connection and control of the electrical lock and the release element.

In addition, EN 13637 also defines special extensions such as B. Time delay or even the complete lock, which may be necessary in certain areas of application. In This European Standard defines the state of the art and applies. However, it has not yet been transferred to building law. For this reason, the directive on electrical locking of doors in escape routes (EltVTR), which has been in force since 1988 (only) in Germany, remains in force. The word escape routes is irritating because it means escape routes. EN 13637 describes in great detail (on 140 pages!) Requirements and test methods for locks on swing doors on escape routes.

Harmonization of standards

The date of publication in the European Official Journal is decisive for harmonization . In some cases, transition periods are also granted.

  • EN 179: 2008, Locks and building hardware - Emergency exit locks with handle or push plate for doors in escape routes - Requirements and test methods
Already harmonized
  • EN 1125: 2008 Locks and building hardware - Panic door locks with horizontal operating rod for doors in escape routes - Requirements and test methods
Already harmonized
  • EN 13637: 2015 Locks and building hardware - Electrically controlled escape door systems for doors in escape routes - Requirements and test methods
