SIRENA T4 LED RED V24DAC

F4 is an integrated LED signaling device engineered for tunnels safe following distrance signaling

T4 is developed to give drivers a rich but yet not disturbing guide light, helping visually measuring the distance from the car in front: amber lights can be placed every 5 meters, to be alternated with one blue light every 25 meters.

This combination allows an immediate perception of the distance with the car in front helping tremendously in case of sudden stops and preventing incidents. T4 has a built-in back-up technology: it has been developed over two independent electronic circuits which function as back-up to one another in case of one circuit failure.
