Can I adjust the door closer speed myself?

This is best left to an engineer, particularly on fire doors or communal entrances where the closing speed and final latching action need to meet the door's certification. Adjustment screws exist but getting the balance wrong can leave the door unsafe.

Why does the free exit button sometimes not release the lock?

This can be a worn switch, a loose wire, or a schedule set on the controller that restricts free exit to certain hours. An engineer can test the circuit and check the controller settings to find the actual cause.

Is it safe to wedge a door open if the closer is faulty?

Not on a fire door or any door forming part of your escape route, since wedging defeats the self-closing function that helps contain smoke and fire. Your fire risk assessment and the responsible person for the building will decide what interim measures, if any, are appropriate.

What is the difference between a free exit button and a break glass unit?

A free exit button is pressed under normal conditions to leave through an access-controlled door, while a break glass unit is typically part of the fire alarm system and used in an emergency. They sometimes sit near each other but serve different purposes.

How often should door closers be checked?

Many buildings include closer checks as part of routine access control or fire door maintenance visits. Your fire risk assessment will generally guide how often this should happen for doors on escape routes.

A door closer works alongside your access control to bring a door back to a latched position after somebody has passed through it, while a free exit button or bar lets people leave without needing a fob, card or code. When either part starts misbehaving, staff notice quickly, whether that is a door slamming shut, a closer arm dragging on the floor, or an exit button that does nothing when pressed.

These two components sit right at the junction between convenience and safety, so problems here are worth taking seriously rather than working around with a wedge or a taped-down latch. A door that will not close properly can leave a secured area open, while an exit device that does not release can trap someone on the wrong side of a locked door during an emergency.

This page looks at the common symptoms owners encounter with closers and free exit hardware, what checks are reasonable to make yourself, and why the fixes almost always need a trained hand on anything connected to the lock, the closer body or the mains supply.

What You Will Usually Notice

The door closer slams the door shut loudly instead of easing it closed

The door swings open under its own weight rather than staying shut

The green free exit button lights up but the lock does not release

The closer arm has come loose or is dragging along the floor or frame

The door does not fully latch, leaving it resting against the frame

Staff report the exit bar feels stiff or needs pressing several times

Safe Checks You Can Do Yourself

Watch the door through a full open and close cycle

Open the door to its usual angle and let it close naturally without touching it. Note whether it slams, stalls partway, or fails to reach the frame, as this description helps an engineer diagnose the closer speed settings quickly.

Check for visible damage to the closer body or arm

Look along the top of the door and frame for a cracked closer casing, a bent arm, or fixing screws that have worked loose. Do not attempt to tighten or adjust these yourself, just note what you see.

Test the free exit button without forcing it

Press the button once with normal pressure and see whether the door releases within a second or two. Repeated hard pressing can damage the internal switch, so a single test is enough to note the fault.

Note whether the fault is constant or occasional

Some free exit faults only appear at certain times, such as after the building has been locked overnight. Keeping a simple note of when the problem happens helps narrow down whether it is a wiring, timer or power issue.

Check nothing is obstructing the door's swing

A mat, wedge, or piece of furniture pushed too close to the door can throw off a closer's timing and make it look faulty when the real issue is something blocking its path.

What Normally Causes It

Closer speed and latch adjustment drifting out of setting

Hydraulic door closers have internal valves that control closing speed and the final latching action. Over time, vibration and heavy use can shift these settings, causing the door to either slam or fail to reach the frame.

A failing free exit button or its wiring

The button that releases the lock from inside relies on a low voltage circuit running back to the controller. A worn switch, a loose connection, or damaged cable can all stop the release signal reaching the lock reliably.

Power or timer settings affecting the exit release

Some systems only allow free exit during certain hours, or route the release through a time clock as part of a wider access schedule. If that schedule is wrong or the controller has lost its clock setting, exit can appear to fail.

Mechanical wear on hinges or the closer arm linkage

Heavily used doors put strain on hinges and the closer's mounting points. As these wear, the door can bind, sag, or swing unevenly, which throws off how the closer interacts with the latch even if the closer itself is sound.

Weather seals or draught excluders adding resistance

New or swollen weatherstripping around a frame can increase the force needed to close a door fully, which a closer set up before the seal was fitted may no longer be strong enough to overcome.

A fire door being fitted with the wrong closer for its rating

Fire-rated doors need a closer matched to the door's certification and weight. A mismatched or incorrectly fitted closer can fail to close the door fully, which undermines the door's ability to hold back smoke and fire.

When to Stop and Call an Engineer

The door is a designated fire door, since its closer, seals and self-closing action must be assessed and set by a competent engineer, never adjusted informally

The free exit button controls a route used for fire escape, meaning any release fault should be treated as urgent and reported straight away

The closer arm or body shows physical damage, cracking, or is leaking hydraulic fluid

Adjusting the closing speed or latch action yourself is not something you feel confident doing, which is entirely reasonable given it needs the right tools and setting knowledge

The exit button fault is intermittent and you cannot identify a pattern, suggesting a wiring or controller issue that needs testing equipment

Keeping it from coming back

A door closer and free exit button used on an escape route are life-safety items, so any adjustment, repair or replacement should sit within your fire risk assessment and be carried out and recorded by a competent engineer rather than tackled informally.
