IP OFFICE 500V2 8.1 w/ Valcom 2001a Paging Problem

[cctech1956]

Hello all: I have an IPO500 V2 With a Valcom 2001a and have not been able to get it to page over external speakers. I came into this after someone had already connected paging and was not able to get it to work. It was setup on an analog extension (201) with a short code of *61. When the paging button was pressed paging was heared through the speakers of the phones but not the external speakers. I looked at the programming setup and it appeared to be correct the way that I read on some of the threads on this forum. I thought it would be a good idea to use a line port, so I tried to setup CO 7 to be my paging port but it didn't work either. I read another post on here that said when you use a line group ID that you must also delete the previous line id that was using that group. I did not do that when I was setting it up. That information was not included in the instructions on how to set up a line port for paging. I am concerned that I am not doing all the steps and that is why it is not working. Is it possible to get a step by step list on how to program a CO port for paging. And after I set it up, should I be able to plug my butt set directly into the CO port on the IPO and make a page.

Thanks, for any input.

I always use analog extension ports. Be sure to set the port to paging speaker under extension/analog. Have you verified the speakers have power?

I have music connected to my Valcom unit and it plays fine. Also if I connect my Buttset directly to the Valcom I can page over the speakers. As I stated before it was setup on an analog extension at first but didn't work. If I pressed the paging button or dialed *61 the display would say "paging speaker", but no sound came out. I read a few posts and got conflicting information so I thought it would be a good idea to use a trunk port. I also tried to use a WMT1a between the system and Valcom an on a couple of tries I got a very faint page. But I could not get it every time. I am trying to get a step by step setup if possible so that I don't leave out anything.

Do you have a 600-680 ohm resistor between the T&R pairs?

 

[pmcook]

Some people advise that you do a cold start on the system after connecting the speaker. The resistor is mandatory t trick the IPO into "thinking" the extension is on hook. I use the Valcom 2001A often on the IPO and it needs nothing else. Use a biscuit and install the resistor between the green and red pairs.

 

[cctech1956]

I don't have a 600-680ohm resistor. Where do you get those? Also I don't follow when you say put the resistor between the tip and ring pairs. Do you mean between the red wire and green wire? Is this done anywhere on that pair? I am trying to picture this.

 

[pmcook]

I get them at Radio Shack which still has some open stores. I also get them at any electronic store or online. A five pack is usually less than 2 bucks. You install the resistor in parallel by jumpering the red and green wires in the biscuit at the screw terminals with the resitor tails along with your cross connect wires then tying down your cross connect to the Valcom and then a RJ11 patch cord to the IPO.

Actually you need to have a separator whic is basically a 600 ohm 1:1 transformator and a 2uF 400V capacitor.
It separate the electronic circuits and protects both systems. See schematic below

This is what I use:

It will work but it is not safe like driving 160 mph on a bike without a helmet.

It will work but it is not safe like driving 160 mph on a bike without a helmet.

it is save to drive, the unsave part is falling off
I have a big scar to prove that falling off at 160 ("only" km/h) can really leave marks but I had a helmet on even though it sometimes seems it hit too hard anyways.

however...I agree with intrigrant that a resistor makes it work but a proper device makes it work well and also keeps it working longer.

I never fell off my bike, i've been close once at 140 km/h in a slow curve but somehow I managed to get the control back. I stopped at a gas station and had a coffe or two to get my hart back on a normal level.

 

[cctech1956]

Is this really dangerous? I dont know if I can pull it off with a separator and all. It seems complicated. I appreciate the input but is there a simpler way? Is the 680 needed if you use a CO port? Or maybe a V9970?

 

[intrigrant]

Analog stations/lines cannot tell the system if it is on hook or off hook like a digital set can.
So what they invented is if the phone is on hook the line is left open ( no electric current in the circuit ) and if the phone/line goes off hook the circuit will be closed. Now if they would shortcut the circuit the running current would be too high to handle so they put a terminator in the circuit to limit the current but enough to trigger a signal to indicate "off hook".
The best value for the line terminator seemed to be 600 ohm (or was it the first resistor the inventor found searching his trash can?)

If you don't have the resistor just wire an analog phone in parallel off of the analog extension port & leave the phone off hook with the handset diconnected. Works great for me.

 

[Westi]

funny that the WMT1A didn't work because that is built for it.
You said that you can hook up the butt set to the Valcom and can page that woudl mean that you have power coming from teh Valcom unit, if you turn that off you should be OK with just connecting it to the paging port.

You know, the very first google hit for Valcom 2001a is the 6 page pdf installation manual. This unit can be used on either a trunk port, or a 600 ohm page port. If you can make a page using your butt set, it is currently set to use a trunk port, and that's what you should connect it to on the IPO. OR, flip the battery feed switch, SW1, to to OFF. Input connections go to the Page T and R terminals, not the modular jack.

An analog phone in parallel? Will that work? I can try that.
