Low Voltage LED Room Information Signs - BIO HAZARD

Compact low voltage signs 

These LED room information signs are extra low voltage (24V DC), low energy, low profile signs. Being relatively compact they can be mounted between door handle and eye height which ensures that they will be seen by someone intending to enter the door.

Low energy LED Signs

Utilising the latest LED technology, these signs are ultra low energy with a power consumption of only 3.6W.

Two State or Three State LED Signs

All room information signs are available as two state signs and some are available as a three state sign. Two state signs are either off, displaying a black screen with no message, or on, displaying the message in yellow. Three state signs can be off, displaying a black screen with no message, on-state A, displaying a message in green, or on-state B, displaying a different message in red.

Secret sign

When off there is no visible message. For three state signs the red and green messages display in the same part of the sign at different times.

Health & Safety Advantages

Low voltage LED signs are inherently safer as there is not the necessity of connecting them to mains electricity. The mounting position at around chest height eliminates the need to have ladders in doorways for installation and maintenance purposes.

Maintenance Free

With a lifetime in excess of 50,000 operational hours these signs are effectively maintenance free hence eliminating maintenance costs and risks.

Power Supply with Switch

For signs that are to be hand switched (rather than automatically switched) a power supply with 2 or 3 way switch is available. This wall or desk mountable unit has clear visual indication of the sign state, including an LED in the end of the switch toggle which lights up the colour of the sign. The power supply can operate up to two compact LED signs.
