The LD6A LED signal towers from IDEC feature an exceptional oval design. Unlike traditional signal towers where the translucent domes are stacked directly on top of each other, the LD6A series separates them with non-transparent plastic, which, along with special lenses that provide triple light refraction, enhances the visibility of signal states. Labeling the individual signals in the gaps is also possible. The base modules are available with a flashing light function and an acoustic alarm. Two different alarm signals can be selected, with the volume adjustable via a slider in the range of 70 to 90 dB. The LD6A series can be combined in the following configurations: frame mounting, wall mounting, floor mounting, and pipe mounting.
