Re: [ViaTalk] Does it work with an ADT home alarm?
The ADT device shouldn't be sending any voltage down the line, so I don't think there are any concerns that it would mess up the Viatalk adaptor.
However, depending on how the alarm was installed, enabling voip service over your existing internal phone wiring may not work. The alarm installer -should- have run the phone line from the Newtwork Interface box outside directly to the alarm control panel, then from the control panel out to the internal jacks. The reasoning for this is so that the alarm control panel can shut off all extensions when dialing - so that if an extension is off hook, the call will still go through.
A -lot- of installers don't take the time to do this properly, especially if it's not a new construction. If the alarm is installed properly, the plugging the adaptor into an internal jack won't work without doing some wiring adjustments at the control panel. |

| poolek, thanks for your reply. Just want to clarify one point you made. You said if the alarm wasn't setup properly, plugging the ViaTalk adapter into one jack will not distribute the signal to other phone jacks in the house? That would make the service unusable. This is bad...
What my parents are most probably going to do is purchase the CellGuard option in the event it won't work with ViaTalk. I believe the only case in which it wouldn't work is if the phone is off the hook, since the ViaTalk adapter won't be wired to seize the phone line.
Am I on the right track in my thinking here? |

| The adaptor will distrubute dial tone to all jacks in the house regardless of whether the alarm control panel is wired correctly or not. The alarm just won't be able to dial out if it's been installed correctly, since when the control panel cuts off the internal jacks to make the call, it will be cutting off the jack the adaptor is on as well.
You can fix this by swapping the 'incoming' vs 'outgoing' wires in the control panel.
If the alarm was installed incorrecly, the alarm should be able to call out. Whether the data transmission over the line will actually work will still need to be tested, but at least it'll be able to get dial tone. |

Wilmington, DE | AH! I get it now. Thanks. Perhaps I can have them do this when they come to install CellGuard. |

| Here's one way to think about it: Suppose you installed a brand new phone jack, ran a pair of wires from it to the RJ31X jack that your alarm is connected to, disconnected the pair that was formerly connected to the phone company's incoming line, and in its place connected the new line from your new jack. Everything would work as before, except your VoIP adapter would be taking the place of the telephone company Central Office.
Well, in most homes you can achieve exactly the same effect without running any new cable or adding any new jacks (unless you want to). All you have to do is rewire an existing jack to use a formerly unused pair as line 1, then out at the network interface device, connect that same pair to the wires going to your alarm system (disconnecting the line from the phone company in the process if you haven't done so already).
Let's say that the brown pair (solid brown wire plus white wire with brown stripe) is unused in your home (as it probably would be if you've never had four incoming phone lines in your home). You would connect the brown pair to the line one position at the jack you want to plug your adapter into (probably where the blue pair is connected now). Then out at the network interface, you would connect the brown pair to the line going to your alarm. As long as the brown pair connection isn't broken anywhere along the path from the jack to the network interface, this should work.
Your alarm system installer should be able to figure all this out, but the point you want to make to him is that your VoIP adapter now takes the place of the incoming PSTN line. Hopefully he'll have seen this situation before and will know what to do.
Some homes may have a central connection point that's not at the network interface device, so you may have to adapt the principle explained here accordingly. But the idea is that your telephone service flows in this direction:
VoIP adapter (takes place of incoming phone line) ---> Alarm (RJ31X jack) ---> Rest of jacks in your home. |

I've done exactly that and now use NextAlarm (with their separate PAP2 adapter) as my monitoring service for the past year. Very inexpensive with nice features. Have not had any reliability issues - and receive SMS or Email alerts for all alarm actions (daily test, arm, disarm, zone fault, zone alarm, etc.). No wiring modifications are required to the alarm panel. |
