A redundant door drive differs from a standard door drive by integrating two motors and two controllers, with battery and a watch dog management security system. Upon the activation of a fire signal, power failure, door malfunction or if the network power is cut off, the sliding door automatically opens and stays open, unless it is in “locked” or “stop” mode. Doors on evacuation routes are always fitted with an emergency switch that is close to the door and provides an emergency opening.

On evacuation and escape routes you can also use automatic fire sliding doors that provide a mechanical evacuation. They function as standard automatic sliding doors, but upon a fire alarm, they transform into swing doors. This provides an easy evacuation through the door leaves.
