House Alarm And Broadband

I have been on broadband via PlusNet since Feb and it has been rock steady.

We are getting out house alarm upgraded and the new system will include an
auto dialler. If the alarm goes of the dialler will ring a pre defined
sequence of numbers and play a recorded message. It is not going to be
connected to the Police or Red Care (as I believe the system is called)

During discussion with the alarm firm I suggested that the dialler will need
to have a filter connected to stop it interfering with my broadband. The
engineer said there was no need. He said that the dialler is only active if
and when the alarm goes off. It MAY interfere when it is dialling BUT by
definition there will be no one in the house so it does not matter if my
router looses sync whilst it is dialling out.

Thoughts anyone please? Should I connect a filter after the engineer has
gone (The dialler is going to be connected to an ordinary BT socket so it
would be easy for me to do this.)

I have a customer who on Monday of this week was told the exact
opposite. However their alarm company wants to hard-wire the modem
into the master socket and have requested the wall-mounted ADSL
splitter unit for this purpose.

No one in the house? Isn't the panic button connected to the alarm
system in many installations and isn't that triggered by someone being
in the house (and being attacked)?

Agree to a test alarm and see what happens with and without the filter
fitted.

I'm interested in this. Our local Scout Camp inquired from the alarm company
if it was possible to install broadband to an alarm line. We were told that
it wasn't technically possible. It's not really a problem as we have a line
used for the fax machine. However in the future, maybe near future, I can
see the possibility of getting rid of the fax line. The number of faxes
today is very small, almost all bookings and inquiries are by email.

Was the engineer just wrong or is there a good reason why it may not be
possible?

Even Redcare is now compatible with ADSL
(http://www.redcare.co.uk/security/products/adsl.htm) so the alarm
company are probably wrong. It may be of course that their equipment
is incompatible with ADSL in the same way that a small number of fax
machines are.

alarm systems are normally connected to a hard wired socket
if there is any other connections to the alarm line and they short out the
alarm modem / dialer cant dial out
if someone plugged a bt plug into a socket with a wire shorted between pins
2 and 5 it would also cause a short
also if your bband adsl modem went faulty it may cause a short

All alarm panels, with the exception of Red Care, should be filtered.
Remember it's not just the calling out which affects the ADSL signal it's
also the hardware which is connected to the line as well(which is why non
filtered extension bells are a big no no)...

Yes, where are you going with this line of logic as a normal phone could
stop the alarm dialing out & plenty of people have their alarms connected to
their normal line (& so can a fax machine/PC modem/Sky digit box or any
other telephony product connect to the line).

The only thing which you need to do is make sure that the feed to the alarm
panel is filtered, easy to do if your ADSL access point is at your main
socket as all you'll need is a faceplate filter & feed the alarm off the
back of that, not so easy, but not impossible to do if you want to use the
ADSL from an extension...

But the OP's alarm isn't connected to the police, so I am not sure if the
alarm will simply ringer the mobile of the person being attacked or what?
Even so, if someone in the house was being attacked, loosing your ADSL sync
would be the last thing I would be worried about! Not sure about you!

One of us is missing the point.

Think you'll find that they haven't got any clue about which point they may
have missed....
