Can anyone install this filter?
If your alarm system connects to the phone line through an 'RJ31X' jack (looks like a standard phone jack, only a bit bigger), then you can install this filter. Click, click, and you're done!
If you don't have an RJ31X jack, you'll have to get your security company to install one first.
What if this doesn't fix my problem?
We sell hundreds of these filters a week and the vast majority of buyers are completely satisfied. In the unlikely event that you are not, you can call for an RMA within 30 days, return the filter, and receive a full refund (except shipping.)
Why is our part number slightly different?
