The LD6A LED signal towers from IDEC have an extraordinary oval design. While in conventional signal towers the translucent domes lie directly on top of each other, in the LD6A series they are separated from each other by non-translucent plastic, which, in addition to the special lenses with 3x light refraction, ensures better recognition of the signal states. The labeling of the individual signals on the spaces is thus also possible. The basic modules are also available with flashing light function and acoustic alarm. It is possible to choose between two different alarm signals, the volume of which can be adjusted by means of a slider in the range from 70 to 90 dB. The LD6A series can be combined in the following designs: - Frame mounting - Wall mounting - Floor mounting - Pipe mounting.
