The Security Notice Door Alarmed 5480 Sign should ensure that people do not attempt to open the door. The sign may even be effective if there is no alarm, as people will not want to take the risk and bring attention to themselves. The sign is AAA photoluminescent and would glow in the dark if there are no lights in an area.
This sign is ideal to prevent a door from being opened and should only be disregarded in a time of emergency.
Fixing requires anything as simple as sticky pads, 'No-nails' type adhesive or double-sided tape.
