Indicator of a successful step
Series of evenly spaced tones that
occur separately. These tones are
slow in comparison with the sounds
that occur when the control panel
sends data.
Steady high-pitched tone together
with rapidly changing connected or
separated tones. The connected
tones occur when data is sent using
modem format. The separated tones
occur when data is sent using BFSK
format.
Data transmission sounds stop.
Control panel does not attempt to
re-dial for the same event.
The equipment completes all steps
successfully, but the central station
has no recorded signals for the
assigned account number.
Modem format uses a four-digit account number. BFSK format uses a
three-digit account number. When programming a BFSK account
number using RPS, the first digit of the account number must be a 0.
When programming any account number using the D5200
Programmer, program the account number into digits 7 through 10.
For BFSK format, program digit 7 as 0, with the rest of the account
number in digits 8 through 10.
