Yes thats the problem i have no documentation! and we dont work with otis company. i dont know how to find documentation on internet... it is geared. What does POR means? i have pictures and i know that there is a display in the controller that says 0--- i know the 0 means that one security is open but i dont have plans and no information i cant not look for it manually and activate it again! If there is a way to send u pictures of controller that would be nice! if u can help me in something i will apreciate this.

thank u very much
