System II:
Our System II door opener will
release and open a locked 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.
For extra security, System II can work with an optional deadbolt
function along with the normally included electric strike plate
door latch release mechanism. |
