The Characteristics of Swing Door Opener

An automatic swing door opener is a tool that works by operating a swing door for convenient use of pedestrians. It works by opening the door mechanically, waits for a few seconds, then eventually shuts it.

3 Fundamental Types

This door opener comes in 3 fundamental types such as full energy, low energy and power assist. The first type, which is commonly used on the outside doors of medium-based businesses, opens then closes the swing door at the fullest speed. The second type opens then closes the swing door operator at decreased speed in order to restrict the moving swing door’s kinetic energy to levels that are considered safe for users with limited mobility. The third type does not open the door, but enables the user to manually open it at a decreased force unlike opening next to a regular door closer.

How is it Triggered?

A swing door opener may be set off in a variety of ways such as through approach sensor which opens the door when someone approaches it, pushbutton which requires the user to press a button, pus and go which opens the door fully when users start opening it, and access control which opens the door when the access control system verifies that a certain user is allowed to go through.

Sensors

In order to thwart the swing door opener from coming in contact with users, it makes use of sensors. Full energy door operators need a minimum of 3 sensors while low-energy door operators don’t need safety sensors because of the fact that the door is permitted to come in contact with users, given the fact that the moving door’s kinetic energy is restricted by the decreased moving speed.

History accounts that door sensors took the form of floor mats sensing the users’ weight, one in the approach side and one in the swing side. The former is commonly utilized as a prompt sensor. On the other hand, the latter averts the swing door from beginning to open as long as other people are sensed in the swing part; in the event that the door begins to open, this mat is disregarded.

Infrared Safety Sensors

To date, there are 4 types of infrared safety sensors used in a swing door closer. They are as follows:

Presence sensor mounted in the header – This safety sensor senses if there is a person that stands in front of the swing door.

Door mounted sensor in the approach side – From the name itself, this is mounted on the door’s approach side. It is used when the door is closing to sense a person in the path of the door.

Door mounted sensor in the swing side– This is mounted on the door’s swing side and is used when the swing door is opening to sense users in the path of the door. The sensitivity of this detector should be decreased at the opening angle’s end part, if it begins detecting a barrier next to the swing door, so that it may not confound it with users.

Safety beam – Wondering how this works? Simple. It crosses the users’ path past the swing side. In the event that it is disrupted, the operator presumes that someone has traversed into the swing area. Plus, it isn’t secure to have the door opened at full speed. Generally, this sensor is disregarded once the automatic swing door has begun to open, as the operator presumes that the users who have gone through the swing door are the ones that have disrupted the beam.

Now, you already know the characteristics of a swing door opener.
