AUT-O-SAFE® Emergency Return Unit

The AUT-O-SAFE® is an auxilliary power supply for your elevator that activates automatically when a building loses power. During a power failure, the Unitec AUT-O-SAFE emergency return unit automatically returns the elevator to the lowest landing and opens the elevator doors to allow passengers to exit. The "door-open" button remains operative to ensure all passengers exit safely. The elevator then remains parked with the doors closed until normal power is restored.
