Had Gardtec Eurosec CPX panel installed replacing old control panel.

Vo-comm has worked intermittently. We get a lot of interference when trying to use landline phone so have to disconnect vo-comm to use phone, to this end we have put vo-comm wires into its own telephone plug.

At the moment we are wired as follows:-

BT Master socket, then Broadband filter, then a double adaptor which has phone and vo-comm plugs into it.

Any help/suggestions would be gratefully received.

1. You say that the vocomm worked intermitently: do you mean that it did not always send it's message when the alarm had activated?

2. When you unplugged or dissed the vo-comm from the line did the "interference" stop?

3. What did the interference sound like? eg was it crackley, hissey, bleepey digitty like a fax etc?

If 1. Susspect main board

If 2. Definitely main board or bad connection between line and main board

Try just plugging the double addaptor into the master socket with the phone and vo-comm plugged into it ie without any broardband filters.

Also if you have any other telephone devices sharing the line disconnect them while you do the tests.

Let us know how you get on.

Best wishes
