Connection to phone line

[Robson689]

I'm looking to connect a Visonic alarm to the phone line. Do I need a microfilter or can I just connect from the master socket into the panel?

Thanks in advance

Yes BT fibre if the package makes any difference
Not fibre to the home mind just the regular fibre to cabinet

Ok so it worked but the master socket is very old and it's not possible to get a reliable connection without it cutting the broadband off so will replace the master socket when I can get one and see from there

One thing I was unsure of was the connection to panel - 2 terminals marked "line" but obviously there is 4 wires coming from the BT 431a plug so I just guessed which to connect black & yellow not sure if it matters
