Patlite launches the LU7-LB sound module for the modular signal towers of the 'LU7' series. Its features include a volume of 100 db/1 m and 360° all-round sound. The sound module is compatible with every LU7 model and is simply attached to the signal tower. The LED signal towers in the series measure 70 mm in diameter and are based on a modular system. Up to five stackable LED modules in the colors red, yellow, green, blue and transparent/white can be combined with each other and with sound modules or low-maintenance, colored LED stroboscope modules. All components of the modular system of the signal light series comply with CE, UL and C-UL requirements and have protection class IP65 (sound modules IP20). The operating temperature is -30 to +60 °C for the DC version and -25 to +60 °C for the AC models.
