On the older model DSC glass breaks they used to attach the microphone
to the cct board via really thin red and black wires (on the order of
32AWG).  If you weren't careful mounting the unit, you'd break one of
the wires.  If you didn't test the unit (using their tester), you'd
never know the unit didn't work.  We recently took over a system in a
restaurant that employed these older units.  3 out of the 6 installed
had broken wires.
