Electronic Alarms and Home Security Devices - DSC 832 Phone alarm

Hi I turned off ATT (hated ATT) and wired my home phone system to Magicjac on my cable road runner highspeed internet connection. But although I get dial tone and connections on all my phones I have the trouble light burning on my alarm. I also notice that on my printer/fax it says phone off the hook. I did nothing to the ATT incomming lines except jumpered the red/green lines and then plugged the other end into the magicjac on the usb port of the computer. I only had the red and green lines hooked up to the box outside and this worked fine when I added a line for my direct TV. The yellow/black lines were never used and when I open the DSC box it is connected to green/red. Do I have some kind of grounding problem or can anybody tell me what to do? I see a couple of other wires comming out of same cable (blue white) but they go to some terminals in the ATT box.
I put a dc volt meter from the black lug on the box to the red then green leads and I saw 24 dc. the red lead on the meter was hooked to the black middle lug on the box when i took the reading. Thanks

ps i saw somewhere about removing battery and unplug transformer. I see battery in box but have no idea where installer put transformer unless it is in the ceiling some where.
I don't think he left me master codes when he installed system 5 years ago. when pushing *2 it gives me a communications error message.

Basically, you have circumvented the normal wiring configuration for the alarm communication (and while magic jack is just fine for voice, it's not so good for the alarm's data transmission).

Normally the red and green wires on the alarm jack get the dialtone from the telephone source, then the pair connected to the brown and grey wire terminals on the RJ-31x jack returns the dial tone to the house phones.

By feeding the dial tone into your house lines by plugging your magic jack into a house jack and disconnecting telco at the DMARC, you are now feeding that jack in reverse. Every time the alarm tries to "pick up" the phone to dial out, it's essentially disconnecting itself from the dial tone.

In the sticky titled "Alarm forum FAQ (Please read before posting)" there is a link that has diagrams to the proper wiring of a RJ31x jack. You are simply substituting your VOIP device for the Telco source. Just realize that the VOIP generated phone line simply may not allow the data transmission (it's trying to compress already compressed data).

Thanks for the info. Since I live in the country I really don't need to be connected to a alarm company so I had discontinued the service (economy, no job) and use the alarm system for smoke alarm, door security and horn. I would like to change the device so the trouble light on the 835 is not burning and beeping. Can you tell me how to do that?

I push # and it will stop for a while and *2 shows communications now (Duh! I was hooking up Magicjack during a thunderstorm and had not cut the leads to the ATT service and lightning fried the magicjack so I will have to get a new one. Florida is great except for employment and afternoon thunder storms:):(). I opened the alarm box and see the battery and the installer probably hooked the transformer in the attic, so I guess I can find that, BUT although I know my own codes, have no idea what the installer codes are.

Can you help?

The instructions for how to disable the dialer are also in the FAQ, but you need the installer code. The factory default is 5010 or 5555, but the odds are that the people who set up monitoring changed it. You may end up defaulting the panel and starting over from scratch.

If you don't already have one, you need the set of manuals for this system. Websearch using the phrase: "DSC PC5010 installer manual" _and_ "DSC PC5010 programming manual" You need _both_. Without the programming booklet, none of the info in the installer manual makes any sense and vice versa.
