Fire protection doors and gates as well as door extension systems

Self-closing fire protection doors and gates and hold-open systems stop smoke and fire. This means that people inside the building gain time to get outside and save themselves.

Cutting off the passage of fire

Fire protection doors and fire protection gates are fire protection barriers. They secure necessary passages between individual fire compartments against the passage of flames, heat and smoke. This makes them central to preventive fire protection in buildings. Fire protection doors and gates must be self-closing. If they must be kept open for operational reasons, hold-open systems are required as door extensions. These close automatically in case of fire. As the doors and gates must be ready for use 24 hours a day, 365 days a year, this fire protection measure requires guidance from the experts.

We’re happy to advise you so that you can find the right solution including the necessary accessories. We can also supply specialist designs upon request.


It can be trickier than you think to decide whether a hold-open system makes sense. But don’t worry, our fire protection experts will be happy to advise you. Get in touch with us.

Selecting and installing fire protection doors and gates

Fire protection barriers must be comprehensively labelled according to DIN 4102-5. As well as a note such as “Fire Door Keep Closed”, the approval plate attached to the door rebate on the side of the hinge is of utmost importance. It contains information on fire resistance class (fire-retardant, fire-resistant), the manufacturer’s name and year of manufacture, approval number and certificate of conformity “Ü”.

Since September 2019, fire and smoke protection barriers may only be used in accordance with DIN EN 16034. The CE marking process based on a classification report according to EN 13501-2 replaces the general building authority approvals and the general building authority test certificate (abP) for smoke protection barriers. Fire protection doors with hold-open systems additionally require a red hand switch with the inscription “Close door” or “Close fire protection barrier” (point 4 of the guidelines for hold-open systems).

How fire doors work with hold-open systems

Fire protection barriers are self-closing. Often the constant opening of the doors hinders daily business and they come at the expense of accessibility.

This is why doors and gates are often wedged or held open with a heavy object. Unfortunately, this stops fire protection doors and gates from working at all. From the point of view of fire protection, keeping these open is considered negligent – legislation considers this a criminal offence. A hold-open system solves the problem and is particularly recommended in buildings where there are lots of people and public transport: Doors and gates can remain open but will close automatically in case of fire. Escape and rescue routes remain usable and the passage of fire to other parts of the building is limited.

Hold-open systems and emergency exit systems

Hold-open systems are attached to fire protection doors and gates which are to remain open during everyday operation. However, these ensure that the door or gate closes automatically in an emergency to prevent the spread of smoke and fire. The same applies for automatic doors. They are subject to annual maintenance by an expert. Various electronic safeguards such as door guard, door control unit or escape door cover prevent the improper use of emergency exit doors. With the help of these door extension systems, you can easily use the protection doors and gates in the event of a fire.

Testing and maintenance of fire protection doors

So that fire protection barriers function perfectly in an emergency, a safety inspection as well as maintenance is scheduled to take place every 12 months. The Technical Regulations for Workplaces (ASR A1.7 Para. 10.2), DIN 14677, accident prevention regulations as well as DIBt guidelines and test certificate of the manufacturer must be observed. According to ASR A1.7, only experts are allowed to carry out inspections. The repair of fire protection doors and gates is also a matter for specialists. ASR A1.7 para. 10.1 specifies that only those who are familiar with the respective repair work may work on fire barriers.

However, hold-open systems have to be inspected each month by the plant operator or their authorised representative as well as annually by an expert. This task is also part of the service of our qualified CWS Fire Safety Team, so you can rely on us. We only use approved materials for repair work and, following the test, we’ll provide you with the required documentation including identification lists.
