The S7400 traffic light is a single-colour signal light for escalators and moving walks – available in green or red and optionally with function monitoring. It is designed for installation in a square column or base.
Signal lights from RLS Wacon show passengers whether the unit is cleared or blocked: green clears the direction of travel, red signals that the unit is blocked. The bright, homogeneous LED illumination remains clearly visible even in ambient light; robust LED technology ensures long, low-maintenance operation.
On request, this product is available with function monitoring: the device continuously checks its own function and automatically reports a failure – such as a defective LED – via a separate output to a remote diagnostics system or the control room. Faults are detected immediately without an on-site check – this increases the availability of the unit and reduces maintenance effort.
The signal light is mounted on the access side of escalators and moving walks and shows passengers whether the unit is cleared (green) or blocked (red).
The display uses backlit LEDs and offers high optical contrast with homogeneous illumination and low power consumption. Nothing is visible on the display when de-energised. Optionally, the traffic light is available with function monitoring for connection to a remote diagnostics system.
