As you rightly say, if you have a filtered faceplate on your master socket -
with all the extension wiring connected to the back of that faceplate - the
extension sockets will be filtered automatically and you won't need
micro-filters in them. If your alarm is an analog device and is hard-wired
into your extension setup, then it will probably work.
Your ADSL modem *must* be connected to an unfiltered connection - usually
the ADSL outlet on the filtered faceplate - and won't work if you plug it
into a filtered extension socket.
In your situation, I think I would buy a modified filtered faceplate from
Clarity [
http://www.clarity.it/telecoms/adsl_bits.htm ] and run a digital
extension from the back of faceplate (one pair of your CAT5 cable is fine -
as is ordinary phone cable) to where the ADSL modem needs to connect.
