Input Point Operation

Refer to Appendix A: Troubleshooting on page 51 for information about error
messages or messages indicating abnormal operating conditions.
The D9068 supports five inputs that can be activated by dry contact relays or open
collector outputs. The initiating circuits or points can be configured for seven
conditions (refer to Table 7 on page 25):

Description
When activated, the D9068 sends a Fire
Alarm Report. A restoral is sent when
the input is deactivated.
When activated, the D9068 sends a
Water-flow Alarm Report. A restoral is
sent when the input is deactivated.
When activated, the D9068 sends a
Supervisory Alarm Report. A restoral
is sent when the input is deactivated.
When activated, the D9068 sends a
Monitor Report. A restoral is sent
when the input is deactivated.
When activated, the D9068 sends a
Trouble Input Report. An input
configured for System Fault is
automatically supervised. A restoral
is sent when the input is deactivated.
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
D9068 with an AC Fail Delay between 0
and 24 hours. You can also program the
D9068 to Wait for DC where the D9068
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 D9068
monitors both inputs. If an AC failure
occurs and the delay time is
initialized, the D9068 looks for a low
battery condition and ignores the
delay to report the condition if
necessary. A restoral is sent when the
input deactivates.
When activated, the D9068 sends a Low
Battery Report. A restoral is sent
when the input deactivates.
System Operation
Additional Information
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 8 on page 26
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 8 on page 26. If System
Fault is set for Fault on
Open, the voltage levels
shown in Table 9 on page 26
apply.
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 8 on page 26
for more information.
