Hi,

I have a residential ADT system installed. Ever since I had it
installed, I hear a background noise when I make a phone call, sort of
a pulsing/hissing noise. Of couse if I call my phone comp. they will
say it is ADT & probably vice-versa. Any way to fix this. Is this
common?

Thanks for any info. :)

We used to see this problem on the old FBI panels, talk about noisy!
You should make sure your 31x is outside your grounded can. It could
also be that your phone line is picking up motorboat from your keypad
ckt., separating your line from the rest of your alarm wiring may
help. I remember one time a tech told us to use some coils and
capacitors to stop the noise. But alas, time has stolen the value of
these devices from me. I do remember not hearing an appreciable
difference in the ambient noise level. He (tech guy) probably just
told me that to get rid of me. -Rick

I doubt very much if you have an RJ31X jack connecting your alarm system to the
telephone line. As ADT usually skips this very vital item in their
installations. This jack usually looks just like a regular surface mount
telephone block except the plug is a little bit wider then normal. Anyway, if
you do have something like this that connects your telephone line, to your
alarm system, disconnect the plug and then listen to your phone. If the noise
is gone, it's the alarm system. It's just that you still won't know if it's the
wiring or the electronics.

There are a lot of possible answers to finding the source of the noise and
I guess it *could* be the panel but I'd be more inclined to think that the
noise was due to the fact that the wire that the alarm company installed, that
connects the alarm system to your telephone line, is probably lying along side
a long wire run of your house wiring.

Depending on how handy you are, you may want to try to follow the wire that
connects your alarm system to the phone lines from the alarm box back to where
ever they hooked it in to the phone lines. See if this wire runs parallel for
20 or 30 feet with any house wiring. Depending upon what is being powered by
the house wiring, 110vac *can sometimes* cause noise on the line. Even more so,
however running parallel to a 220vac line such as an electrict stove or clothes
dryer wire, will almost defintely cause a problem.

Alarm keypad wiring can sometimes cause a slight and fairly rapid motorboat
"ticking or pulsing " sound on phone lines also.

Sometimes even light dimmer wall switches and even TV sets can cause noise in
telephones.

In any event, the only real sure way to find out is to completely disconnect
the alarm system from the telephone line at the main junction splice which is
usually at the demark out side of your home. If the system is wired for line
sizeure, as it should be, you may be confused by the hook up at first. But it's
hard to know if thats how yours was done with out further information from you.
Once you completely disconnect the alarm system in this manner, if the noise is
still there, then you can call the Telephone company and then they can't blame
it on the alarm system.

You'll have to trace it out and discover the source of the noise by process of
elimination or get someone who has some trouble shooting experience to do it
for you.

As an alternative, I guess you could scream and carry on like a crazy person
with the alarm or telephone company until they responded. );-> Or as a last
resort, you could momentarily hook 220vac accross the phone lines and let both
companys come and replace everything.

Disconnect your telephones and computer first ...though.

Naw ... don't do that, I was just kidding.

Micho:

The noise you hear on your phone line may be induced into the phone wiring
many ways, but here is something that may have happened:

If the alarm installer used multiconductor alarm cable to run devices,
(keypads, sirens, whatever) to the alarm control, and if that cable also
carries any telephone wiring, the keypad data wires WILL induce noise into
the phone wires. And, if this is the case, unplugging the RJ31X will not
stop the noise.

I've seen rookie alarm installers do this, and the only way to fix it is to
separate the telephone wiring to the from the keypad wiring. They may not
be run in the same cable because wires inside alarm cable are not twisted as
in data cables.

If you're sure the noise is being caused by the alarm, i.e. the noise began
the day the alarm system was installed, then call ADT and demand, not
request, demand that they send an experienced tech to fix it right away.
Don't pay them a penny until they do.

How long since it was installed? If it was less than six months, call ADT
and tell them to fix it. There should be no service charges for this
repair. If they do not respond and you are less than six months, quote
their satisfaction guarantee and cancel the service. There are lots of
other service providers out there who are as good or better than the ADT
office in your area.

According to the info I have, the jack comes as part of the basic resi
package. What proof do you have that ADT doesn't install the RJ31X?
I'd be happy to follow up with the offending branch.

Btw, this is sort of like me saying that small, local companies use
single-dialer residential burglar alarm panels in their commercial FA
installs, string BA zip-wire around risers as FA cable, and run 30
contacts on one zone. All things that I've seen, but that doesn't
mean they're typical of all small companies.

Hi Micho,

Of course, your best course of action is to call ADT and have them
send an experience tech to check out the installation. Are you
certain that the problem started when the system was installed? Phone
line noise is a fairly common problem, but sometime isn't noticed by
the installation tech. It should be easy to fix, however. Keep in
mind that ADT does have a money back if you're not satified program.

No it's not common. Either the new wires connecting the alarm are near a
source of interference and must be moved, or the problem is caused by your
current wiring near something generating noise.

Have you recently installed or bought another appliance like a computer or
TV or something that emits radiation?

Great, but don't forget, that might not solve your problem. Make sure you
listen to the telephone line at your noisiest phone with both the RJ31X jack
plugged in and with it removed. Make sure that the reason for their service
call is written on the ticket so that if you have that problem in the near
future, you can't be charged for the second visit, if they have to come back to
work on the same problem.

If the noise is still there, they should remove the alarm telphone wire
completely from the telephone connections. Then listen to the line. If the
noise is still there then you have to call the telephone company. While testing
your phones during the alarm disconnect, someone should listen to the telephone
lines both at the demark and at each of the inside phones. If the noise is
still there, disconnect all of you telephones except one. listen on the line.
If the noise is still there, substitute that handset for another of a different
type and listen to the line again. If the noise is STILL there, then it's the
telephone companys problem.

Make sure that you mention that you have DSL service. This could be tied
to your problem. Not an ADT problem, but a DSL problem. Perhaps they can
install a filter for you.
