FireNET FN-DAC Digital Alarm Communicator I & O Manual - v 1.0
2.5 Communicator Operation
This section describes some of the basic operational features of the FN-DAC
communicator / dialer.
2.5.1 Phone Line and Phone Number Selection
The FN-DAC can be configured with up to four account numbers and four phone
numbers. Each phone number corresponds to an account (phone number 1 is used
with Account 1; phone number 2 is used with Account 2, etc). This allows for
programming of backup and duplicate reporting configurations.
Events are communicated to each account in order and by priority, beginning with
Account 1. The communicator will begin the dialing sequence using phone line 1,
unless phone line 1 has failed. If the communicator cannot report events successfully
using phone line 1, it automatically switches to phone line 2.
Account 1 and account 2 are used together for primary and backup reporting. If
duplicate reporting is needed, account 3 may be used, with account 4 serving as its
backup. Table 2.5.1.1 shows how the accounts and phone lines are selected when
reporting an event (both phone lines in normal working condition).

Table 2.5.1.1 – Communicator Account and Phone Line Selection
*Note that the same sequence applies when accounts 3 and 4 are used.
Since the communicator selects the phone line to be used, both lines must use the
same dialing sequence. If one phone line requires that a “9” be dialed, it cannot be
used with a second line that does not require a “9”.
