ADSL and alarm: passive filter ?????

Hello,
For the installation of an ADSL master filter with an alarm, see the diagram on page 9/16 in PDF format (1st installation guide):

Hi, I work at an alarm company (I install). I know that the most recurring problem is that the alarm transmitter is connected before the filter... To find out, it's simple: 1- Notify your monitoring company about the tests you are going to perform 2- Connect to the internet 3- Trigger your alarm so that the transmitter makes a call 4- Check if your connection was interrupted... If it was, it means your alarm panel is connected before the filter, so modify the wiring... If you don't see how to do it, contact me... @+ :o)))

Hello, I have the same issue. I have a telephone alarm, several filtered telephone sockets, and a passive filter I bought from FT (€30), and it doesn't work. I think the passive filter is not installed correctly. If I could find the solution, I would be very happy. For your information, I was with Télé 2, it didn't work, so I switched to Free, and the problem remains the same. Thank you for your assistance.

It is true that method 8 is particular, yet the beginning is realistic
a bit of advertising at Darty!
Ah the Darty box!!!
you need to provide the phone and also the bank details
I don't understand the point of this free advertising and I ask for explanations about the tax exemption for hours at 80 euros?
Are these hours for childcare? for service vouchers? or simply a bonus for the environment if we use green colored cable?

There are indeed many other technicians capable of solving an ADSL issue for a telephone transmitter
It should also be added that we are straying from the subject
basically 6 wires on the filter
2 for FT arrival
2 for ADSL output (which are directly connected to the input (no filter))
2 to filter the rest of the house

The filter is a "master" filter and is installed at the head of the line
The transmitter must have 4 terminals
2 for the filtered input (line)
2 for the return to the stations in the house

That's it!

Hello,
See if this can help you; I did it but with this filter. If the form changes, the principle remains the same.

Hi Manu!

Could you give me the reference for this "master" filter, because I also have an alarm system and I want to avoid any hassle as much as possible.

For my case, the problem was solved as follows:
on a standard line socket are connected in order:
1: the plug coming from the transmitter
2: the ADSL filter
3: the plug of a standard phone.
and the operation has been perfect since the beginning.
note: the security system and the transmitter are from the brand DIAGRAL, installed by myself.

Hello everyone,

For those who have a lot of "metaphysical" questions about "how to make the telephone, ADSL, and an alarm system with a PSTN transmitter coexist within the same installation," the answers to all your questions...

Can be found in the installation manual for ADSL filters from LEACOM:
(http://www.leacom.fr/Images/Upload/faq/datasheet_installation_filtre_ADSL_LEA_Ed02.pdf)

(http://www.leacom.fr).

All possible installation variants are presented with simple, commented principle diagrams.
(pages 14 and 15, for example).

The filters can even be purchased online.

However, a few remarks:

- Telephony, networking, and anti-intrusion security require solid technical skills.

- If you are just a "Sunday handyman," don't take it as derogatory, think carefully before "putting your hands in"!

- The worst-case scenario is as follows:

1) you install the master filter, you get mixed up (between the pairs, the inputs, the outputs, the light blue connectors, etc.),

2) the cables of your installation end up being too short,

3) you extend them with connectors,

4) the ADSL modem no longer synchronizes (you picked the wrong output on the filter....),

5) the transmitter of the intrusion detection system can no longer transmit, detects a line fault, and triggers a local alarm.

6) Finally, you can only call France Telecom when the alarm transmitter finally gives you the line, and that's precisely when the internal siren sounds again.

7) After the tenth call, made possible by turning off the intrusion detection system (main power fuse, battery of the control panel and those of the sirens otherwise it keeps ringing), the France Telecom technician explains that the service call will be charged €100 and will only aim to restore your telephone installation (unless you are subscribed to Wanadoo) for the rest you will still need to contact your alarm installer....

8) Do not call your ISP, there is no home maintenance service for subscribers

9) Good luck!!!

A quality alarm telephone transmitter is connected as a priority in order to take the line, making sure to hang up and pick up the handset again so that an undesired person does not occupy the line during a burglary; as such, it naturally cuts off all other phones, faxes, etc., in order to send its voice messages, SMS, or digital signals (if you are under remote surveillance). Therefore, it is necessary to connect it to a filter; however, the supraphonic signals of ADSL cannot pass through a filter (since it is there to block supraphony...)
The solution used by professionals is to install a filter/no-filter switching card remotely controlled by the transmitter.
This is quite common but is difficult to apply to wireless alarms, which are mostly just gadgets...
You can forgo this card if your ADSL modem is connected directly to the FT line head, but this is rare and very impractical, and may cause other problems. (An installer!)

Hello everyone,
I also have an alarm connected to the phone line, and my question is how this alarm reduces the ADSL speed since it seems to call in case of a problem, so at worst it could interfere with the connection during these calls.
But for example, I have the Freebox connected to one of the "regular" sockets in the installation and I have a speed of about 150kb/s, and if I connect it to the socket where the alarm is plugged in, I have a speed of about 500kb/s, that's quite a difference.

Thanks, see you later!

Thank you for all this information, especially the LEA link (formerly ALCATEL).
A small remark.
If you follow the ADSL schematic with the transmitter, that's good.
Don’t be tempted to put a simple filter next to your PC on the ADSL line to have the phone because you will immediately lose the advantage of the "line head". And yes, your new phone will be prioritized over the rest of the installation and a lucky thief will unplug your phone before "borrowing" your PC.
The transmitter won’t be able to take the line!!!
Don’t forget the advice flflfl!!!

Regarding the flow modifications, there can be X solutions.
The first one: it's not the socket that's faulty but the transmitter itself!!!
From the little information provided, it seems like this is an alarm for individuals with a transmitter connected to a standard telephone socket.
The transmitter internally can filter the incoming flow...
Do the same manipulation: disconnect the transmitter and this time test the flow on both sockets.
If the flow is 500k, then it comes from the transmitter.
It is also possible that there is the FT capacitor in the second socket and not in the first (allows for FT line tests but reduces the ADSL flow when it can be above 8M).
In any case, repeat the measurement several times because the ADSL flow is not constant and such variations naturally exist on the network.
Good luck :)

Be careful when switching to ADSL with a central...
some transmitters are sensitive to parasitism related to ADSL communication and randomly generate line faults.
It's better to filter the transmitter even though apparently it's not happening.

Sure, except for point n°8
There is a home maintenance service for ADSL and telephony at DARTY.
Thank you for correcting this omission.
