Do Not Enter Signs

RT Technologies provides a complete portfolio of Do Not Enter signs. We offer contemporary LED signs (low profile LED and large display LED) and traditional illuminated laser warning signs for all applications.  Custom wording for the display is available on all warning sign displays, and both single-aspect signs and double or dual aspect signs are available.

Extra low profile, low voltage (24V DC), low energy warning signs. These signs are available as one state (one message – yellow text) or two state (two messages – red and green text).  Typically, the sign is hard wired to 24V which triggers the message of the sign.  Alternatively, a power supply with 2 or 3 way switch is available.  This power supply also converts 110V to 24V.  This wall or desk mountable unit has clear visual indication of the sign state.  It includes an LED in the end of the switch toggle which lights up the color of the sign.  In addition, custom wording is available at an additional charge.




The Ultra signs are state of the art LED technology in a highly aesthetic design.   These slimline signs can be mounted at any height without causing obstruction or hazard. Additionally, custom legends and colors are available to suit your application.









Weatherproof Ultra

The sign is IP66 rated to B560529 which means that the sign is protected against powerful water jets and is dust tight.  The text color comes in several different options.   Perfect for any outdoor application.
