Designed with safety in mind, SafeZone® uses a multi-point, electromechanical closer and a programmable motion sensor. When the door is opened manually, SafeZone senses movement in the door opening and stops the door from closing. When movement is no longer detected, the adjustable setting times out and the door closes. SafeZone detects movement in both directions, allowing one person or a stream of people to travel through an opening, making it ideal for , hospitals, doctor's offices and rehabilitation or assisted living facilities.
