An automatic door closer (more often called a "door opener") opens the door itself, typically under the control of a push button, motion detector or other device, and then closes it as well, typically employing a motion or proximity detector to determine when it is safe to close the door.
Rixson was the first architectural hardware company to have fire/life-safety closers and holders. It remains an industry leader with several distinctly different holding devices. The Smok-Chek V Series serve many purposes. The models come as detectored with a built in smoke detector or non-detectored models which would be connected only to the alarm system.
