What Is An Automatic Door Opener?

September 21 , 2022

For office doors or fence gates in residential areas, when installing access control, read the card to unlock, and need to manually open the door. In order to be more automated, an automatic door opener is introduced, that is, when the card is read, it not only opens the lock but also automatically opens the door. There are The electric lock is no longer installed, and the access control is used to directly control the control point of the automatic opening and closing of the door operator. When there is no card reading signal input, the door operator automatically closes the door.


There are three forms of common automatic door openers: the first one looks more like a door closer, but the door closed just closes the door, and the door opener is also responsible for opening the door. Its shape is larger than that of the door closer, and there is a motor inside. And the access control panel, as well as the travel switch, are driven by the motor to open and close the door. The installation position of this method is the same as that of the door closer, above the door, and close to the door shaft.


The second appearance is more like a floor spring, and the installation method is the same as that of the floor spring. It is buried in the position of the door shaft and used to replace the original floor spring. This door switch should be installed under the door. Use the motor to twist the door shaft to open or close the door.


The third type is installed on the side of the door, like a door bow, one end is installed on the door leaf, one end is installed on the door frame, most of them are installed in the middle of the door, and the pulling arm is extended or shortened by hydraulic pressure to open or close the door.


In order to realize the anti-pinch function of automatic door opening and closing, it is sometimes necessary to install a device such as infrared radiation at the door. When there is someone at the door, the door will not be closed. Only when there is no one at the door for a few seconds, the door can be closed.


Use the access control to connect the automatic door opener, just control the door to open the door, that is, the control output of the access control controller outputs COM and NO, and takes the switch signal. If the output of the access control is only an electrical signal, you need to use a relay to convert it into a switch signal. Control the door opener.
