The Patlite models LU5 & LU7 are modular signal towers with 1 to 5 colour modules and an optional alarm buzzer in the base. The LU5 has a diameter of 50mm, the LU7 70mm. The modular design allows the sequence to be changed easily by hand whilst maintaining an IP65 enclosure. Further details are in the cataloghe pages.
From 2017 the LU5 and LU7 are superceded by the new LR series with diameters 40, 50, 60 and 70mm. Therefore where it is important to match the diameter, the LR5 (50mm) and LR7 (70mm) can bespecified.
The features of the LU5 and LU7 are carried over to the LR with additional advantages:
improved visibility with up to 2 x more light emitted
optional non-directional IP65 buzzer with 4 different sounds and volume reduction
-construction with tougher materials for increased shock resistance.
