What Is the Purpose of a Fire Door Closer?

Fire Door Closer

A fire door may appear deceptively simple. To most people, it is merely a heavier door with a few specialised fittings. In reality, however, a properly installed fire door is an important component within a building’s wider fire safety arrangements, and its ability to close correctly is fundamental to the protection it is designed to provide.

This is where the fire door closer becomes particularly important.

A fire door closer is designed to return a fire door to its closed position after somebody has passed through it. Its purpose is to ensure that the door is not inadvertently left open, where it may be unable to restrict the movement of fire and smoke.

For landlords, property managers, facilities managers, businesses and homeowners in Bournemouth, Poole and across Dorset, understanding how a fire door closer works is therefore an important part of understanding fire door safety as a whole.

What Is the Purpose of a Fire Door Closer?

The principal purpose of a fire door closer is to ensure that a fire door closes automatically after it has been opened. A closed fire door can help restrict the spread of fire and smoke between different areas of a building, supporting compartmentation and helping to protect escape routes and occupants.

Government guidance describes fire doors as one of the most important measures used to safeguard means of escape from fire. It also makes clear that a fire door which does not close fully into its frame will not adequately hold back fire and smoke.

The closer is therefore not an incidental fitting. It is part of the arrangement that allows the door to perform its intended function.

What Is a Fire Door Closer?

A fire door closer is a mechanical device that controls the movement of a door and returns it to its closed position after use.

The familiar overhead closer is perhaps the type most people recognise. It usually consists of a metal body fitted to the door or frame, together with an arm that controls the movement of the door.

Other forms of self closing device are also available. The appropriate system will depend upon factors including the door, its specification, its location and the way the building is used.

The essential point is not simply that the door moves towards its frame. A suitable closer should enable the fire door to close properly and overcome any resistance necessary for it to settle into its intended closed position.

Current Government guidance for relevant residential buildings recommends checking whether the door will close fully into its frame both from a fully open position and from an opening of around 15 degrees.

Why Does a Fire Door Need to Close?

A fire door principally provides protection when it is closed.

Buildings are often divided into sections so that fire and smoke can be contained for a period of time rather than being allowed to travel freely throughout the premises. This principle is commonly referred to as compartmentation.

A properly performing fire door helps preserve these barriers. When the door is left open, however, there may be a direct route through which heat, smoke and fire can travel.

This is precisely why the closing mechanism matters.

Government information published in connection with the Fire Safety Regulations states that fire doors are crucial in preventing the spread of fire and smoke. Residents in applicable buildings must also be given information explaining that fire doors should be kept shut when they are not being used and that self closing devices should not be tampered with.

The closer therefore performs a simple action with potentially significant consequences. It removes the need to rely entirely upon somebody remembering to close the door behind them.

Are Fire Door Closers a Legal Requirement?

There is no useful universal answer which says that every fire door in every building must have precisely the same type of closer.

The applicable requirements depend upon the nature of the building, the purpose and position of the door, the fire strategy and the legislation or guidance relevant to the premises.

For premises within the scope of the Regulatory Reform Fire Safety Order 2005, the responsible person has duties relating to fire precautions and fire risk assessment. Government guidance confirms that responsibility for fire safety in relevant non domestic premises rests with the designated responsible person, who must assess risks and provide appropriate fire safety measures according to the circumstances of the premises.

There are additional requirements for certain residential buildings in England.

Since 23 January 2023, responsible persons for multi occupied residential buildings in England with storeys more than 11 metres above ground level have been required to arrange quarterly checks of fire doors in communal areas, including their self closing devices. They must also use their best endeavours to undertake annual checks of flat entrance doors leading onto common parts, including the associated self closing devices.

This is why fire door requirements should be considered in the context of the particular property rather than reduced to a single rule.

Can You Adjust a Fire Door Closer Yourself?

Some door closers have adjustable settings, but that does not necessarily mean that untrained adjustment is advisable.

Changing closing force or speed without understanding the door specification can create another problem rather than solving the original one.

A door that shuts slowly enough to stop before reaching the frame is clearly problematic. At the opposite extreme, simply increasing the closing force without investigating resistance or alignment could produce an unnecessarily aggressive closing action while leaving the underlying defect untouched.

If a fire door is failing to close correctly, the cause should be established rather than guessed.

Its current website states that its team has undertaken FireQual approved training and that the business is listed on the UK Fire Door Approved Map.
