This is a release and open a locked (or unlocked) door, pause for entrance or exit, close automatically, and then return the door to its locked position. If you would like to extend the time the door is open, you can do so by pushing the remote control again. The door will stay open as long as you like. To close the door, simply push the remote once again. Leaves the door free-swinging for manual use.

Important note: Our product is not recommended for use with doors that are typically manufactured by window companies with proprietary 3-point locking systems, which have upper and lower latches (or pins) as well as a latch on the side.

There is no way to electrically release the upper and lower latches to allow the door to open automatically. Also, the latch on the side of the door may not be a standard type latch, it may be a deadbolt type latch or it may be a latch of some proprietary size/shape. The entire door handle set and latches may have to be removed and replaced with a standard locking door handle and latch.

Additionally, these kind of doors may have very heavy door seals or weatherstripping, that requires a lot more force than usual to open or close. This may require experimentation with regard to the door operator and arm mounting positions in order to overcome the resistance of the tight seals.
