The difference between electric door closer and automatic door opener


Electric door closers are also called automatic door closer releases, fire linkage door closers, normally open fire door closers, etc., and their role is to control the positioning, release and closing of normally open fire doors. Usually, keep the fire door normally open from 0-170°, and the fire protection linkage monitoring system can realize the automatic closing of the fire door in sequence through the electronic control method.

The automatic door opener is a drive composed of a motor, a variable speed structure, a clutch device, etc., and belongs to an electromechanical product. Usually used to control the electric opening and closing of various doors.


It supports 2ways to work:


1: Standalone, Connect it with 220V or 110V power to open or close it directly.

2: Connect with RFID Door access control systems, here is the wiring diagram.

In summary, the difference between electric door closers and automatic door openers is obvious. Electric door closers can only control the positioning and automatic closing of the door, not an automatic opening. Because the automatic door opener is driven by a motor, it can realize the automatic opening and closing of the door.


There are also differences in the scenes used. Electric door closers are generally used for normally open fire doors, which must be able to automatically close the door in case of fire and isolate the fireworks. The automatic door opener is suitable for channel casement doors, which can realize intelligent induction and contact-free automatic door opening and closing, and can also access the access control system to open the door by swiping the card or fingerprint.


Note: The automatic door opener cannot be used for the evacuation door of the fire passage, because the automatic door opener needs to be driven by electricity, it cannot guarantee the effective door opening in the event of a fire, and does not meet the fire safety requirements.
