1.0 Overview
Phone Line Selection
The FPT-DACT follows a predetermined sequence to
choose between the two telephone lines. It also
implements the new NFPA requirements for alternating
telephone lines during test reporting: the FPT-DACT
maintains a variable that selects either Phone Line 1 or
Phone Line 2 for Auto Test Reports. After each
successful Test Report, the variable switches to select the
other telephone line. Users can select the telephone line
for Manual Test Reports.
Communication Failed Indication: The FPT-DACT
indicates a communication failure after ten attempts to
communicate are completed without success. This
causes the trouble output to activate and attempt to
report the fault.
1.2.8 History Buffer
The FPT-DACT has a history buffer that retains up to
100 events. Each event is tagged with the date and time
of occurrence. This buffer can be viewed when a FMR-
DACT Keypad is attached to the FPT-DACT. When the
buffer is full, old events are discarded to make room for
new events. A watchdog reset is entered in the buffer
and does not reset the buffer.
The history buffer might clear when the
system loses power for more than 5 min.
