Auto Dial
This is a feature that automatically dials (through a customer supplied PC-compatible modem) a pre-
programmed telephone number (up to 12 digits) when specified alarm conditions occur within the
UPS system. Automatic dial attempts to the first number are made at periodic intervals for 30 min-
utes. If unanswered, the system rolls over to the second number and repeats the process until connec-
tion is made.
Upon connection, the system transmits data, in RS-232C format, that includes the system identifica-
tion code, the present alarm message(s) and the time that the alarm(s) occurred. Refer to 3.2.14 -
Communication Interfaces.
Refer to the Special Functions column in Table 4 to see which alarm messages will initiate an auto-
dial call.
If the auto-dial numbers were specified at time of order, the numbers are pre-programmed into the
system. However, if the numbers need to be changed, follow the steps listed below to reprogram the
auto-dialer.
