Self-closing devices and hold-open: the rules for fire doors

11 May 2026 5 min readBy The DoorTRACE Team

A fire door only works when it is closed. That sounds obvious, but it is the single most common way fire doors fail in practice: propped open with a wedge, held by a fire extinguisher, or fitted with a closer that no longer pulls the door fully shut. A perfectly specified, perfectly maintained fire door standing open offers no protection at all.

This article explains how self-closing devices are supposed to work, when it is acceptable to hold a fire door open, and the closer faults inspectors see most often.

What a self-closing device must do

Most fire doors are required to be self-closing. The device, usually an overhead closer, must return the door from any open position and close it fully into the frame so that the latch engages. The test an inspector applies is straightforward: open the door to various angles, including just a few degrees, release it, and confirm it closes completely and latches every time, not just from wide open.

The closing action also needs to be controlled. A door that slams can be a hazard and can damage the assembly over time; a door that closes too slowly or stalls part-way may not shut before smoke spreads. A correctly adjusted closer does the job reliably and at a sensible speed.

Why "fully closed" is the whole point

Fire doors are part of a building's compartmentation, the division of a building into areas that contain fire and smoke. A door that is ajar, or that closes against the frame but does not latch, leaves a gap that fire and smoke move through. Latching matters because the pressure generated by a fire can push an unlatched door open. This is why "closes but does not latch" is recorded as a failure, not a minor note.

When can a fire door be held open?

There are legitimate reasons to want a fire door held open: accessibility, heavy traffic routes, or simple convenience in a busy corridor. The rule is that a fire door may be held open only by a device that automatically releases it on fire detection, so the door closes when the alarm sounds. Acceptable approaches include:

  • Electromagnetic hold-open devices linked to the fire alarm system, which release the door when the alarm activates
  • Free-swing closers linked to the alarm, which let the door move freely until the alarm triggers the closer
  • Acoustic or self-contained release devices that respond to the alarm sounder, used within their limitations

What is never acceptable is holding a fire door open with a wedge, a hook, a tied-back cord, an extinguisher or any other object that will not release in a fire. These are among the clearest and most serious failures an inspector can find.

Common closer faults

The faults inspectors record most often include:

  • A closer that no longer closes the door fully, leaving it ajar
  • A door that closes but does not latch
  • A closer with the wrong adjustment, closing too fast or too slowly
  • A leaking or worn closer that has lost its power
  • Hold-open devices that are not linked to the alarm, or that have failed to release

Many of these develop gradually as a closer wears, which is why regular checks catch them before they become a problem. They tie into the wider inspection checklist and the standards in BS 8214.

The human factor

Closers and hold-opens are also where occupant behaviour shows up most. Doors get wedged because they are inconvenient. Part of meeting the Fire Safety (England) Regulations 2022 duty to inform residents is helping people understand why a fire door must be allowed to close, and giving them an easy way to report a closer that is not working rather than wedging the door as a workaround.

How DoorTRACE helps

DoorTRACE captures closer and hold-open checks as part of every inspection, with photos and notes, and turns any failure into a tracked defect until it is fixed and verified. Recurring closer problems on a particular door become visible across its history, so you can replace rather than repeatedly repair. See the platform or book a demo.
