power horn siren in italy dont work

[giacomo]

I ìve bought a x10 system but the 2 power
horn sirens doen't works maybe because i've
plugged in with 2 transformers because in
Italy we use 220 volts

If you put the lamp module in place of the
powerhorn can it be controlled? Can you try
the powerhorn on the same transformer as the
DS7000 as a test?

DEAR BRIAN
thanks for your reply. I have 2 DS700 with 2
transformers, I have not a lamp module cause
I wasn't interested in so i can do the test,
the 2 ds7000 works right as the other
wireless device,(I have 22 doorwindow, 4 PIR
and 4 keychain remote all functional, ) only
the 2 plug in sirens dont work

Although not specifically mentioning the Power Horn, it does give general suggestions on getting X10 devices to work on 220V systems.
