This 8-bit value is passed to sounder controller on the falling
edge of the alert input; these 7 bits define duration and
frequency only; sounder command bit D0 is ignored and
fixed internally at 1; if an alert sound is sent as 000xxxxx
(continuous), then the command is stored as 111xxxxx
(1000 ms)
