4.0 System Operation
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
keypad and press [1] for Status.
Refer to Appendix C on page 49 for the
specific messages sent for each event.
Low Battery*: When activated, the FPT-DACT sends a
Low Battery Report. A restoral is sent when the input is
deactivated.
* Depending on the input voltage level (from 0 V to 5 V)
for these selected 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
on page 22 for more information.
Alarm operation is independent of
supervision. If an input point is not
supervised and no EOL device is attached,
the input point still activates for the event
type for which it is configured if the voltage
is below 1.3 V or above 2 V.
Refer to Figure 16 for the System Fault and Fault on
Open wiring connections.
To prevent a Trouble Report from generating
every time a system fault occurs, verify an
EOL resistor is connected to the FACP
output relay as shown in Figure 15 on page
17.
When the FPT-DACT is configured for
serial operation, it only detects alarms and
faults on the inputs when the serial link is
broken. When the serial link is active, the
inputs are not monitored for off-normal
conditions.
4.3 Trouble Relay Operation
An input programmed to signal a trouble condition
from the FACP does not affect or activate the on-board
trouble relay. The on-board trouble relay activates on:
• any on-board FPT-DACT trouble condition
• internal diagnostic faults
• telephone line supervision faults
• input point supervision faults
• communication failure and faults
Refer to Appendix A on page 45 for
information on error messages or messages
that indicate abnormal operating conditions.
