Which fire door signs do you need?

Most self-closing fire doors in non-domestic buildings and common parts need a 'Fire door keep shut' sign on both faces. Cupboard and riser doors kept locked need 'Fire door keep locked' on the outside. Doors on hold-open devices need 'Automatic fire door keep clear'. Flat entrance doors and doors inside dwellings usually don't need signs.

The three common signs

  • Fire door keep shut — self-closing fire doors, both faces
  • Fire door keep locked — cupboards, risers and stores kept locked
  • Automatic fire door keep clear — doors held open on alarm-linked devices

Which doors are exempt?

Doors within dwellings, flat entrance doors and some hotel bedroom doors are usually exempt from signage. Your fire risk assessment should confirm.

Do signs affect the fire rating?

Signs are fixed to the face with adhesive or small fixings and don't affect the rating, but avoid drilling through to the core with large fixings.

Common questions

Do you supply signs with new doors?

Yes — we fit the correct sign for each door's use as part of installation.

Do signs need to be on both sides?

For most self-closing fire doors in common parts and workplaces, yes.
