Frequently asked questions

How is this different from a 'Keep Locked' sign?
This sign adds a second instruction - the door must stay shut as well as locked. That matters for fire doors, where staying closed maintains compartmentation, not just security.

What sizes does the sign come in?
Three sizes: 150mm x 200mm, 200mm x 300mm and 300mm x 400mm, so you can match the sign to the door and viewing distance.

Which material should I choose for a plant room door?
Vinyl composite is the most durable option and the only material with horizontal or vertical channel fixing, useful where the door sits within a frame or barrier rather than a flat face.

Does the photoluminescent version still work if the power fails?
Yes. It charges from ambient light and stays visible for a period in the dark, useful on fire doors in stairwells and corridors.

Can this be fixed to a riser cupboard or storage door rather than a full fire door?
Yes. The sign is suitable for any door that needs to stay shut and locked, including riser cupboards, plant rooms and general storage doors, not only fire-rated doors.

How is the sign fixed to the door?
Self-adhesive vinyl sticks straight to a clean, flat surface. The other four materials use drill-fix, and vinyl composite additionally offers horizontal or vertical channel fixing in every size.

Is this suitable for outdoor use?
Yes. All five materials are rated for indoor and outdoor use, so the sign can go on an external fire door or gate as well as inside a building.
