NEC DSX Door Box I am Stumped!! - 11/09/10 06:41 AM
I have a DSX 80 that we installed a NEC controller and door box.The door box and controller came for another site where it was working fine.
What is happening at the new site is when you press the button on the door box, nothing happens. You can call the door box from a phone and all works fine.
If we short the wire at the door box (simulating like we are pressing the button)The phones ring, and we have communication to the door box.
Okay, that says to me that my wire going to the controller is good, my controller is good, the digital port the controller is wired to is good and my programming is good.
So we condemn the door box and order another one, we go back to the site, install the new door box and have the same problem. :shrug:
I have the tech bring the new door box back to the office and I use a multi-tester to check and see if I get a short across the two terminals when I press the door box button. The test shows that I indeed get a short across the two terminals when the button is pressed.
What am I missing here????
Thanks
Walter
