I'm having big problem. Customer has one C.O. line only. Line goes to alarm, KSU , maybe somewhere else too?

I have the gate coming into Door King 1875 bypass switch then into CO port 4 on 308 EC card.
Gate can call into the system and line 4 lights up with distinctive ring pattern.
But when customer wants to go off hook on CO line 4 and call down to the gate to activate closure options we get no dial tone until I plug the return side of 1875 bypass switch into an ext. Currently Ext. 22.


This is how it was wired by someone else before I swapped out ACS 308 processor in March 2016.
But before his two 206 cards went belly up last week , it seems that it worked good.
Now I have ACS R6 slot 3, 308 EC slot 1, and Partner Mail VS 5.0 slot 2 in 5 slot carrier.

Because there is only one live C.O. number on premises it seems that when you press line 4 button to call down to the gate Line 1 shows busy red light as I would expect.

But now when calls come in from outside world gate seems to seize the dial tone at certain times and then Ext.22 stays busy and holds the line?
Also some calls ringing in then cause Line 4 distinctive gate ring to be triggered. Apparently these last 2 problems were not occurring before.

Any concrete ideas? Thank you!!

1st, how was the system cards in what slots before you changed them.

As I remember one of this forum's moderators Tommy (Touch Tone Tommy) has a lot of experience with Door King as well as of course Partner. If he doesn't see this thread I would send him a PM.

Thanks Hal, yup, saw your thread on the other forum. Don't put the actual telephone company dial tone on the Door King at all. Take a station from the Partner, remove all line appearances, run that to the Door King's input. Run the Door King's output to CO-4 on the Partner. Make sure everyone's Auto Line Select doesn't include line 4.

Visitor presses the Call button, line 4 on the Partner phones rings. You can answer and dial the code to let them in. If you don't have a call in progress, and just want to open the gate, pick up Line 4, you're actually getting Intercom dial tone from the station port, but the Door King is listening for the code to open the gate.

The manuals are easy to find with Google.

TTT, because the door king uses the 1875 bypass switch, the original wiring by another installer has co line going to 1875 bypass switch on pins 1,2 then to the actual gate on pins 3,4 from the co line 4 port on partner, then out from gate back to 1875 bypass switch on pins 5,6 which then goes straight into KSU on Ext. 22 port. Then if there was actual dial tone it would then leave the 1875 bypass switch on pins 7,8 and feed the house loop wiring.
I believe though the old co line 2 ( or 3) is dead cuz customer originally had a different co line running to the door king and now he only has the one main line. The door king is just being used to communicate with Partner from the gate. It's completely confusing me

originally system had slot 1 206 ec card
slot 2 206 ec card
slot 3 ACS processor 6.0
slot 4 Partner Mail VS

Now I just have slot 1 308 EC
slot 2 Partner mail VS
slot 3 processor

Just so you know, the Partner Mail should b e to the right of the Processor.

No, the Partner Mail placement in slot 2 is correct, since the ACS is in the center slot, and the 1st expansion module (the 206) is in slot 1.

Here's the bypass switch:

Pins 1&2 are either Telephone Company Dial Tone, or a Single Line Intercom Only station from the Partner
Pins 3&4 go to the IN of the Door King
Pins 5&6 go to the OUT of the Door King
Pins 7&8 go to a CO PORT on the Partner, NOT a station port.

In the Bypass mode, the dial tone on 1&2 just goes to the phone/CO port on 7&8. Entry mode puts the Door King in the loop, just like an alarm RJ-31X

so it seems that it was wired strangely but worked, and now it does not??
I'm racking my little brain, but appreciate all the good help
Because it has co 4 going to pins 3,4 then pins 5,6 go to Ext. 22
even though I think the co from Telco is now dry

Listen to what Tommy said. Forget how it was done originally by someone who had no idea. I think they confused connecting the Door King to a house that has one phone line and single line phones. Why would the Door King even need the CO line in this case?

Even easier- get rid of the bypass switch and connect CO #4 of the Partner to terminals 4&5 (phone out) of the main terminal.

Pins 3&4 and 5&6 is the cable going to the Door King. Make the connections to the Partner as shown (except the only picture I could find was an R6, so use CO-4 and Ext. 22 instead of CO-3 and Ext. 17)

Real quick Hal,, as you know sometimes water gets in conduit and rots through cable. the bypass switch is designed to allow you to override any future problems.
Also by pass switch should be hooked up to a good ground to help dissipate lightening strikes, surges, etc.

Seriously TTT, some gidget has pins 3,4 going to Co 4 of Partner and Ext. 22 back to 5,6 no lie!!

I have worked on these before, without Partner system and I know how I wire them, but sometimes I like to err on the side of caution.
Obviously it was working before I was ever called.
Today I set Ext.22 to Int. only.

Gate works but when incoming call comes into Line 1 after 3 rings hits L4 button and activates distinctive ring for gate?? I think bypass switch was hit with spike, but customer does not want me to troubleshoot further at this point.
Thank you to Hal, TTT and others on both sites for bearing with me through this thread.

Tommy, as I mentioned above, it looks like the Door King will provide battery and dial tone on pins 4&5 for connection directly to a KSU CO line when put in the intercom mode. There is no need for the bypass card. Or is that not the unit he is working on?

That's pins 4&5 of the Door King itself, not the Bypass Switch. Pins 4&5 of the Door King are wired to pins 5&6 of the Bypass Switch. But yeah, set the Door King to Intercom Mode, get 4&5 of the Door King to a CO Port, and it should be golden!
