Re: Can a Napco system & DSL connection co-exist?



Splitting hairs even further, why take the chance on a single phone line for
your alarm system?  "Seems like a no brainer" to include cellular or
wireless backup for every installation but how often is it done?  Mr. Bass
was correct in his response.  In reviewing the OP's diagram (however crude
it was), you don't need a filter for the alarm panel to communicate with the
monitoring facility.

Don't get me wrong, I'm not taking sides here.  I agree with "Petem" that
there is a risk (however small) of a problem developing in the DSL line and
that the correct way to wire any single line communicator would be to use
the Excelsus Filter to eliminate even that small chance.

Before this particular filter was on the market, the only way to ensure
uniterrupted DSL and alarm communication was to wire the PROT exactly as the
OP describes.  I'm certain there are still many installations out there that
retain this type of wired connection.  What are you (the industry) doing to
address these?

Frank
