Got a problem with a LUADS doorphone. It will signal the programmed phones but after the doorophone is activated by the button, whoever responds to the depressed call button cannot hear the caller nor can the caller hear the responder. To make sure tht the unit was working properly, I de-installed the unit from the door entrance (about two hundred feet from the ksu) and instqlled it at the mdf. Works without a hitch from there. Thinking thqt I could improve the chance of it working but doubling the tip/ring pairs to the unit at its remote location but to no avail. Still can;t get it to work. I tried different pairs altoghther but no-go. It has worked in the past. Can anyone guide me? This is driving me nuts!

Al :bang:

It's a simple doorphone and one pair of wire. If it works back at the KSU it's gotta be you...

No, it isn't me. I understand how it is installed. Although I didn't install it originally, I have installed many doorphone units of all different varieties. I should say that when I go off hook with my butt set across the tip/ring, it works fine at the remote end. I have been installing equipment for 30 years and am very methodical in my approach. But thanks for your suggestion. The person who originally installed the equipment did such a poor job that little works well on that site. I have actually improved the quality of their communications since taking over the account. They are maxed out in a utility room that is so poorly configured, the frame is a joke. No sir, it isn't me. Thanks anyway. I will resolve it. Ultimately, I always do!

If it works at the control unit, then it should work at the location it is installed. IF (Did I say if) the cable is good. Two hundred feet is no problem for that unit.
Have you tried running a new cable?

The door phone should be programed to pick up intercom dial tone and then dial a group.

If it's one that takes dial tone and sends a call waiting tone. Change the option in the door phone.

That option never works that great.

Is this the older Lucent door Phone that Valcom acquired?

The door phone should be programed to pick up intercom dial tone and then dial a group.

Not exactly. Partner has a doorphone function that works like a hotline. One needs only to program the extension as a doorphone and the extensions that will be alerted when the button is pressed. The Partner doorphone is a simple T/R phone that basically only has to go off hook, no need for it to dial anything.

Charles - take a look at the item being discussed here: https://www.paging-solutions.com/PDFManuals/54-2106-01A.pdf - as Hal says, it's just a single line phone that goes off-hook, and the Partner does the rest.

I'm with Mike; the trouble lies in the cable run between the door and the Partner.

Neither distance nor polarity is an issue, so it's down to how much time you want to spend troubleshooting the existing cable run.

With all the installation experience you have, I'm sure you know not to rely on a toner alone to locate suitable pairs. Use a multimeter to find the short, ground or whatever it is that's killing the voice path. I'm willing to bet that there's a splice, tramped pair or a breach in the cable jacket somewhere (especially after the way you described the pre-existing wire elsewhere).

Who ever makes it and the manufacture has changed twice in the last 10 years..

Viking and Harris come to mind.

What I am saying is that the door phone is on a ex. and not a call waiting feature like a default Chamberlain model and some vikings without the option removed.

It needs to go off hook on intercom dial tone and speed dial the group of stations assigned.

As Hal said, whatever.

The Door phone does not need to be program as a hot line. In fact, I have never programed one as a hot line and never will.
