Hes probably referring to the Protector Plus or the
Monitor Plus system, since those are the only two
systems that have a dialer. There is no way to
really silence the alarm, The only way you can do
that is, to open up the unit and disconnect either
the black or red wire to the piezo siren. Round
gold looking thing. do it in a way that if you want
to use it again you just have to twist the wires
together and put some electrical tape around it.
This will void warrantee. Good Luck
