Actuators - Traffic Lights As Safety Devices (Red / Green)

By Albany Door Systems

Traffic lights, either red/green or only red or only green for visual coverage, can be combined with each actuator.

They serve safety requirements.

Example:

  • Normal position of the door (both lights off)
  • Opening impulse(both lights red)
  • Door is open(one light red, one light green)
  • Closing impulse (both lights red)
