I'm going to be replacing a CTX100 with a NEC SL1100 system soon and was observing the current hook up for the door phones on site. They currently have 2 Viking W-2000a door boxes connected to RC-2A controllers. The controllers are then connected to trunk ports 5 and 6 on the CTX. OK so far. The customer releases the door strike by pressing what appears to be a line key. For the door box on line 5, he presses line key 7 (this is what is in the display). However, there is no connection for line 7 (????).
A couple of things I should add. There are no connections made on the relays for the Viking controllers, and, on the CTX, I see only 1 pair coming from the relay located above some RCA in/outputs. (One relay, 2 door strikes??)Coincidentally, one door strike does not work.
Now, I'm going to replace both door boxes when the new system goes in, but I was wondering how the frig they got this to work? Thoughts? Not a Toshiba guy, but I am curious.

Besides the lable on the phone, is there an indication that the bitton is really a line 7? I bet it programed as a code, using the N/O contacts on the processor to release the door strike.
The RC-2A should be doing the door strike release. While on the door phone the users would enter a pre-determined code which would open or close the contacks on that device.

Usually dialing 16 would close the contact on the RC2A to operate the door opening. Most likely speed dial digits 16 are programmed in that button labeled [Line 7].

newtecky, The label on the phone read "door Open". When I pressed the button, the display read "line key 7". Again, there is no connection to the contacts on the RC-2A. I thought there might be something programmed under the button to release the strike also.
As for the other door strike that doesn't work, I'm wondering if it ever did? Heck, I only see the one relay on CTX. The plot thickens.

This can't be that hard to figure out for gush golly sakes. Think about it.

Power stands at one side of the door strike (usually) and it is some kind of voltage, AC or DC, 10 or 12 or 16 or 18 or 24 volts.

Find one wire that goes from the power supply to the door and look for the other wire that goes from the power supply to the phone system to the door.

It doesn't matter much what that button says that opens the door, it matters what that button ACTUALLY IS. It could say line 7 but be line 8.

At a resort I had multiple gates to open and used unused CO lines to close dry contacts for a front and back gate. Press line 7 and the front gate would open, press line 8 and the back gate would open and there were dry contacts hooked up to CO 7 and CO 8, no dial tones.

Remember, the two sockets on the dial tone motherboard are lines 1 to 4 and the bottom socket on the daughterboard is 5 and 6 and the top socket on the daughterboard is 7 and 8, just to be sure.

I betcha you figure it out.
