Range
Description
Open 4.0 VDC
to
5.0 VDC If voltage on the
input exceeds
4.0 V, a point
trouble is
indicated. EOL
supervision is
required.
Normal 2.0 VDC
to
3.0 VDC If voltage on the
input floats
between 2 V and
3 V, the input
operates normally.
EOL supervision is
required.
Short 0.0 VDC
to
1.3 VDC If voltage on the
input falls below
1.3 V, the input
activates for the
event type for
which it was
configured such as
fire, water-flow,
or supervisory.

Range
Description
Open 4.0 VDC
to
5.0 VDC If voltage on the
input exceeds 4 V
and EOL supervision
is not present, the
input indicates a
point trouble and
activates for
System Fault or
Fault on Open.
Open 2.0 VDC
to
3.0 VDC If voltage on the
input is between
2 V and 3 V and EOL
supervision is
present, the input
activates for
System Fault or
Fault on Open.
Normal 0.0 VDC
to
1.3 VDC If voltage on the
input is between
0 V and 1.3 V, the
input operates
normally.
The AC Fail Delay time set for
the FACP is independent of the
AC Fail Delay time set for the
D9068. When you program the
FACP for an AC Fail Delay time
and then program the D9068 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 D9068 AC Fail Delay
time is set for 12 h, the AC
Fail Report is sent from the
D9068 18 h from the time of AC
failure.
All inputs are non-latching. A
restoral is sent when the input
is deactivated.
For fail-safe operation,
program the system fault to
Fault on Open.
To view specific active events,
connect the D7033/FMR-DACT-
KEYPAD Keypad Programmer and
press [1] for Status.
Refer to Appendix C: Fire
Communicator Report Summary on
page 56 for the specific
messages sent for each event.
Alarm operation is independent
of supervision. If an input
point is not supervised and no
EOL is device attached, the
input point still activates for
the event type for which it is
configured. The voltage must be
below 1.3 V or above 2 V.
Refer to Figure 17 for the System Fault
and Fault on Open wiring connections.
To prevent a Trouble Report
from generating every time a
system fault occurs, verify
that an EOL resistor is
connected to the FACP output
relay (
Figure 17 ).
