FPT-DACT | Operation & Installation Guide | 4.0 System Operation
Unless it successfully sends the report, the FPT-DACT
twice tries sending a Manual Test Report. This can take
up to 3 min. The reports' priority are re-evaluated on
each telephone call attempt. If a higher priority event
occurs while attempting a Manual Test, the higher
priority event is sent on the following telephone call.
Refer to Appendix A on page 45 for
information on error messages or messages
indicating abnormal operating conditions.

Input Point Operation

Refer to Appendix A for information on error
messages or messages that indicate
abnormal operating conditions.
The FPT-DACT supports five inputs that can be
triggered by dry contact relays or open collector
outputs. The initiating circuits or points can be
configured for seven conditions:
Fire*: When activated, the FPT-DACT sends a Fire
Alarm Report. A restoral is sent when the input is
deactivated.
Waterflow*: When activated, the FPT-DACT sends a
Waterflow Alarm Report. A restoral is sent when the
input is deactivated.
Supervisory*: When activated, the FPT-DACT sends a
Supervisory Alarm Report. A restoral is sent when the
input is deactivated.
Monitor*: When activated, the FPT-DACT sends a
Monitor Report. A restoral is sent when the input is
deactivated.
System Fault**: When activated, the FPT-DACT sends
a Trouble Input Report. An input configured for System
Fault is automatically supervised. A restoral is sent
when the input is deactivated.
AC Failure*: When activated, AC FAILURE appears on
the keypad. To decrease the number of reports sent to
the central station such as during a blackout, program
the FPT-DACT with an AC Fail Delay between 0 and
24 h. You can also program the FPT-DACT to Wait for
DC where the FPT-DACT must detect an AC failure on
one input and a low battery condition on a second input.
If there is an AC Fail input and a battery input, the
FPT-DACT monitors both inputs. If an AC failure
occurs and the delay time is initialized, the FPT-DACT
looks for a low battery condition and ignores the delay
to report the condition if necessary. A restoral is sent
when the input deactivates.
* Depending on the input voltage level (from 0 V to 5 V)
for these input configuration types, the input operates
normally, activates for the event type for which it is
configured, or indicates a point trouble. Refer to Table 6
for more information.

** If an input point is configured for System Fault, and
System Fault is set for Fault on Short, the voltage levels
are those shown in Table 6. If System Fault is set for
Fault on Open, the voltage levels shown in Table 7 apply.

The AC Fail Delay time set for the FACP is
independent of the AC Fail Delay time set
for the FPT-DACT. When you program the
FACP for an AC Fail Delay time and program
the FPT-DACT for an AC Fail Delay time, the
AC Fail Delay times are added together. For
example, if the FACP AC Fail Delay time is
set for 6 h and the FPT-DACT AC Fail Delay
time is set for 12 h, the AC Fail Report is
sent from the FPT-DACT 18 h from the time
of AC failure.

Description
If voltage on the input
exceeds 4 V, a point
trouble is indicated. EOL
supervision is required.
If voltage on the input floats
between 2 V and 3 V, the
input operates normally.
EOL supervision is
required.
If voltage on the input
drops below 1.3 V, the
input activates for the event
type for which it was
configured (such as fire,
waterflow, or supervisory).
Description
If input voltage exceeds 4 V
and EOL supervision is not
present, the input indicates a
point trouble and activates
for System Fault or Fault on
Open.
If input voltage is between
2 V and 3 V and EOL
supervision is present, the
input activates for System
Fault or Fault on Open.
If input voltage is between
0 V and 1.3 V, the input
operates normally.
