Emergency Displays (EDNE Displays)
In a public environment, many situations can arise where you may need to prevent people from entering an area during an emergency; fire alarms, spillages, moving machinery, security control and bomb alerts can all be genuine reasons to restrict access.
A low maintenance solution with negligible running costs is a state of the art illuminated visual warning sign from Data Display, our so-called ‘Emergency Do Not Enter’ (EDNE) sign. It is suitable for a wide variety of security applications but, was originally developed for London Underground to satisfy stringent fire regulations prevalent in underground stations.
Our standard units are available with the most frequently needed wording (‘Emergency Do Not Enter’ for example) but can also be supplied with alternative wording or special pictogram to suit the specific application. Using ultra-bright LED technology, the electronic displays are highly visible even in harsh conditions such as direct sunlight and in adverse weather such as dense fog. A ‘hidden-til-lit’ message is designed to be unobtrusive with the message concealed under normal operation but becomes clearly visible once activated. Integrated flashing lanterns and alarm sounder are an added design feature to maximise the impact of the display.
Normal operation of the sign is by means of a contact closure. As an option, an additional model enables complete compatibility with Apollo and Hochiki fire alarm interfaces or can be adapted to any other existing industry standard fire alarm loop.
Data Display has now developed a brand new third generation Emergency Do Not Enter display the EDNE Mark III complete with crowd control function. The new crowd control feature allows the EDNE display to be used as a means of minimising dangerous crowd congestion caused by peaks in passenger flow or station evacuation.
