well!.. it is an automatic swing door system. The operation is something as below.
- When i press “A” button of the key chain signal transmitter, the receiver unit will detect the signal and open one door (right side only).
- When i press “B” button of the key chain signal transmitter, the receiver unit will detect the signal and open both door (left side and right side).
- When i press “A” button of the key chain signal transmitter, the receiver unit will detect the signal and open one door (right side only). During the half way through, when “A” button of the key chain signal transmitter press again, it will stop the door which is opening. or when the opening door that hit on some object, it will stop half way through (safety protection).
It is mainly use for controlling the outdoor gate system. Hope this is clear enough to you…
