The Signal Light S3500-Y (E) is a yellow fault indicator. It offers high visual contrast with low power consumption and homogeneous illumination.
Use on escalators and moving walkways
Direction-of-travel indicators from RLS Wacon signal the direction of travel or clearance of the unit to passengers on escalators and moving walkways. The permissible direction of travel is signaled to passengers via color or symbol. Depending on the version, installation is in a balustrade, round or square column, or base. The bright, homogeneous LED illumination remains clearly visible even in ambient light; when de-energized, no symbols are visible. A curved, replaceable front lens and a wide input voltage range ensure robust continuous operation.
Features
- for installation in square columns or bases with 35 mm diameter
- straight front lens, replaceable
- wide input voltage range
