Frequently asked questions

What does this sign mean?

It's a mandatory instruction telling anyone approaching the door that the fire door must be kept locked at all times, to preserve its fire-resisting function.

What sizes are available?

100mm x 100mm and 200mm x 200mm - choose based on how visible the door position needs to be.

Which material should I pick for an exterior fire door?

Rigid PVC, foam PVC or vinyl composite all suit outdoor fixing; self-adhesive vinyl is best kept to a smooth indoor surface.

Can it be fixed to a metal fire door frame rather than the door itself?

Yes - the 200mm Vinyl Composite option is also available with a horizontal or vertical channel fixing, suited to metal frames, posts or barriers as well as flat drill-fix mounting.

Why choose the photoluminescent version?

It charges under normal lighting and stays visible if the power fails, useful for stairwells and corridors during an evacuation.

Is this sign suitable for a hotel or apartment block?

Yes - it's designed for fire doors in hotels, warehouses, apartment blocks, commercial kitchens and laboratories.

How is it fixed to the door?

Self-adhesive vinyl sticks directly to a clean, smooth surface; the other materials are supplied with drill holes, and the 200mm Vinyl Composite is also available in a channel format.
