Electric door closers are also called automatic door closers, fire linkage door closers, normally open fire door closers, etc., which are used to control the positioning, release, and closing of normally open fire doors. The fire door is usually kept in the normally open state of 0-170°, and the fire-fighting linkage monitoring system can be used to realize the automatic closing of the fire door in sequence through the electric control method.
The automatic door opener is a drive composed of a motor, a variable speed structure, a clutch device, etc., a microwave sensor, and is an electromechanical product. It is usually used to control the electric opening and closing of various door leaves.
To sum up, 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 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 use scenarios. Electric door closers are generally used for normally open fire doors, which must automatically close the door in case of fire and isolate fireworks. The automatic door opener is suitable for aisle swing doors, which can realize intelligent induction and contact-free automatic door opening and closing, and can also access the access control system by swiping a card or fingerprint to open the door.
The automatic door opener cannot be used for the fire escape evacuation door, because the automatic door opener needs to be driven by electricity, it cannot guarantee the effective opening of the door in the event of a fire, and does not meet the fire safety requirements.
