    Once the dialtone is filtered using a adsl filter, the ADT box can use it just like any other dialing device. Don't let them BS you.
    The common alarm company mistake is to make the wiring outside at the demark point go through the alarm system first, then feed the house. If the phone line is not filtered at that point, then the alarm system may have troubles dialing out.

    When weighing the additional cost of the cell connection, you must also consider the possible savings of not having a land line.

    To be clear, the bold above is the correct way to connect an alarm system to the landline. A proper install will result in a two pair run from the demark to the alarm panel as this is the only way to achieve "line seizure" during an alarm event. Plugging an alarm panel into a standard house feed will not result in proper "line seizure", but is unfortunetely how many connect the panel. The demark should feed the panel, then the panel should feed the house...

    This was true before DSL and Vrad service was introduced. And would still be true if the alarm company placed dsl filters at the alarm box after install.
    But it happens all the time now where the alarm is installed this way with no regard to other provided data services running over the phone line.

    It's still true, but the correct install should include the DSL filter. "Line seizure" is an incredibly important aspect of an alarm system, and can only be achieved through a direct feed from the demark to panel (panel then feeds home.) Installing any other way can get an alarm company in trouble, especially if they tout a UL install (UL requires the above setup.)

    A secondary option, to utilizing the DSL filter, is to place the DSL signal on the home's second line (if available.) By segregating the DSL from the "phone" line any DSL problems can be mitigated.

    Either way is viable, but sacrificing the direct demark to alarm panel feed should never be an option. When dealing with alarm systems it's considered a safety issue.

    My quick comment on this subject was not meant to start a p***ing contest between a telephone guy and an alarm tech. But I think if any dedicated criminal knew the first thing about phone lines he would slam an axe into the wall below the outside demark anyhow, eliminating either circumstance we have produced.

    This why I bury my and all my friends and family's lines into the house. It is inconvenient for a service call, but a better bet for security. I also leave the abandoned outside telephone access visible for any potential criminal to have a false sense of hope and time.

    Huh? I thought it was a respectful discussion, and I'm not an alarm tech....

    Most modern alarm panels are able to sense a cut phone line and trigger an alarm condition. I would bet that most alarm techs either do not know this option is available, or do not know how to enable it though... I'm in full agreement that burying the phone lines is a great way to go though. The visable phone line on my house is actually a tamper wire tied to my panel ;)

    I didn't see the need of an alarm company either until my house was robbed. Although they didn't take much (because I didn't have much to take back then) it was still an eye-opening experience. They even took the orange juice out of my fridge, drank it, and left the carton in the middle of the living room floor. It was bad enough that they took my stuff, but to make themselves at home in MY home really ticked me off. Now that I have a family, we'll always have an alarm system.

    The commercials that show someone trying to break in while a woman and daughter are in the house alone may be over-the-top. Still, I would guess most people were like me and don't even think about an alarm until something bad happens but I guess that doesn't make for a effective commercial.

    Until one realizes that the $500/year you pay for monitoring usually gets you in the neighborhood of an $850/year discount on you homeowners insurance.... at least in my case it does.

    Sorry about the assumption. I've been in too many spirited discussions with alarm guys I guess.

    After working for the phone company for several years, I am sold now on getting a cellular back up panel. I am pricing them now.
    During hurricanes we can go for weeks with no power and no phone. Makes you want to sit home on the porch with a loaded gun.

    Ditto. I ended up throwing everything opened in the fridge out.

    This is the set up that I have. I bought it on Ebay. Easy to install and have had no problems. This is not the free filters that the phone company sends.

    Wow. I was gone over the weekend and am quite amazed at the number of responses to what I thought was a pretty benign inquiry. Who knew.:lol: There are several posts I want to respond to but first let me back up and explain my circumstance and why I am interested in the filter.

    I currently have C* internet but AT&T has finally got their fastest speed to my house. They also are offering no contract and a $200 gift card. I thought I would give it a try. After a month if I don't like it I can quit and keep the $card.

    I had ADT installed a couple of years ago (after a burglary of course:grin:) and was able to talk to the installer at length before the install. As a result I fished a 4/pair phone line from the demarc to the ADT panel. I used one pair from demarc to supply panel and another pair from panel back to demarc and hooked that to the POTS line. Which brings me to the issue of filtering.

    I initially called the national ADT# and was told about the need for "their" filter. I want to thank MikeS for the filter part# and dsw2112 for the ADT panel info/ alarm website. (http://www.diyalarmforum.com/). It saved me a lot of footwork. I also called AT&T and was told I absolutely needed a filter and they would have to send a tech to install it for about "cough" $150. No thanks.

    Today I emailed Excelsus the manufacturer of the filter for an explanation of the difference between the panel filter and the regular dsl filter. It appears they supply both ADT and AT&T. No response yet. I also called my local ADT dealer/installer and surprise, surprise I get a whole different story. He says there is no need for any filter at the panel.:eek2: They have not used any in years. Any dsl "data noise" cannot trigger or impede line seizure in the event of an alarm. The filters are for any dsl/data/static noise during the use of the phone only. The most important issue is to have the ADT panel on the line side (before any phones, dvrs, faxes etc) of the POTS.

    He was adament that they have never had an issue without a filter. He says if I don't believe him he will sell me the filter for $40 and an "I told you so" when I find out I don't really need it.:lol: Or if it makes me feel good use one of the regular AT&T dsl filters. He also told me to go online start downloading a VOD movie, surf the net then call ADT with my cell and trigger a "medical" (silent) alarm. It won't fail.:nono2:

    Now all I have to do is decide whom to trust, the people trying to sell me or the guy warning against it.:confused: The only thing I have to lose is all my stuff.:rolleyes:;)......EDIT: I just realized this was my 500th post. I think I got my monies worth.
