Frequently asked questions

What does 'keep locked shut' mean compared to 'keep locked'?

Both instruct people to keep the fire door locked - this version adds 'shut' to the wording for extra clarity that the door must stay closed as well as locked.

What sizes are available?

100mm x 100mm and 200mm x 200mm - choose based on how far away the sign needs to be seen.

Which material suits an exterior fire door?

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

Can it be fixed to a door frame instead of the door face?

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.

Is the photoluminescent version needed if the door already has emergency lighting nearby?

It's a useful backup - the sign charges under normal lighting and stays visible if the power or emergency lighting fails.

What kind of buildings is this sign designed for?

Fire doors in hotels, warehouses, apartment blocks, commercial kitchens and laboratories, or any building with doors that must remain locked shut.

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.
