Frequently asked questions

What does this sign mean?

It warns anyone approaching that the door is fitted with an alarm and that opening it will trigger an alert - it doesn't lock the door itself.

Does the sign trigger the alarm, or is that a separate system?

The sign is a warning only - the alarm itself is a separate door contact or sensor system fitted to the door; the sign just tells people it's there.

What sizes are available?

100mm x 100mm and 200mm x 200mm, so you can match the sign to how visible the door needs to be.

Which material suits an exterior 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 gate or barrier rather than a door?

Yes - the 200mm Vinyl Composite option is available with a horizontal or vertical channel fixing for posts, barriers and gates, as well as flat drill-fix mounting.

Is the photoluminescent version worth it for this application?

It's useful where the alarmed door covers an emergency exit or stairwell - the sign charges under normal lighting and stays visible if the power fails.

Where would I typically fit this sign?

Anywhere an alarmed door needs a clear warning - hotels, warehouses, apartment blocks, commercial kitchens and laboratories all use it.
