Frequently asked questions

How is this different from the smaller Fire Door Keep Shut sign?

This version comes in three larger sizes, 150mm x 200mm up to 300mm x 400mm, for doors that need a bigger sign or are viewed from further away - the smaller 100mm/200mm version suits tighter spaces.

What sizes are available?

150mm x 200mm, 200mm x 300mm and 300mm x 400mm - pick the size based on how far away people need to read it from.

Can the Vinyl Composite version be fixed to a post or barrier at any size?

Yes - horizontal and vertical channel fixing is available on the Vinyl Composite option across all three sizes, not just the largest.

Which material suits a busy warehouse door?

Rigid PVC or vinyl composite are durable enough for frequent handling and wipe clean easily; save self-adhesive vinyl for smoother, lower-traffic surfaces.

Does the sign need to say 'locked' as well as 'shut'?

No - this wording covers doors that must stay closed to contain fire and smoke, whether or not they are also locked. Check your fire door schedule for the wording that matches the door's actual requirement.

Is the photoluminescent option worth it for a stairwell fire door?

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

Will this sign suit an apartment block or hotel corridor?

Yes - the larger sizes are well suited to corridors and communal areas in hotels, apartment blocks and similar premises where the sign needs to be seen from a distance.
