Path # IP Add4
Default: 0
Selection: 0 to 255
Refer to Path 1 IP Add1.
Path # PortNum
Default: 7700
Selection:
1 to 65535
This prompt specifies the destination port number for
each of the four enhanced communication route path
destinations. All four IP address-and-port pairs must
be unique to ensure that event acknowledgments are
accounted correctly. Duplicate address-and-port pairs
are not supported.
Path # Poll Rate
Default: 0
Selection: 0, 5 to 65535 sec
0
Disables the heartbeat poll (not
recommended, refer to the first
Important Note that follows).
5 to 65535
Enables the poll rate for the amount
of time programmed here.
This prompt and the next two prompts determine how
the SDI Path is supervised between the SDI device
and the central station receiver(s). Do not confuse
the SDI Path supervision with the supervision of the
SDI device itself (the connection of the SDI device to
the control panel). Each SDI Path can be configured
to transmit a Heartbeat Poll to the central station for
supervision purposes. This ensures the integrity of
the connection at all times.
If using IP Addresses as the
communication means for UL 864
Commercial Fire applications, program
this parameter as necessary.
When sending reports to a central station
receiver over a network path, you must
set Path # Poll Rate to a non-zero value.
Failure to program a value into this field
could prevent a failed network
communications path from restoring to
normal.
If the control panel is programmed to
send Heartbeat Poll to the central station,
a rate of 75 sec maintains the virtual link
in most network configurations.
Decreasing the value for Path # Poll
Rate increases the amount of idle
communication between the SDI device
and the central station receiver.
Increased idle communication between
the control panel and the receiver
decreases the control panel’s event
reporting efficiency.
The control panel readjusts the Heartbeat
Poll rate temporarily to less than 300 sec
to 300 sec when online with RPS. The
poll rate returns to the programmed value
after the RPS session ends.
The value programmed in Path # Poll Rate is the
interval at which the control panel sends a Heartbeat
Poll to the central station receiver. The value
programmed in Path # Ack Wait is the length of time
the control panel waits for an acknowledgment of a
Heartbeat poll. If the acknowledgment is not
received, the control panel checks to determine if the
Path # Retry Count entry is greater than 0. If so, the
control panel retries the number of times
programmed (in Path # Retry Count) to send the
Heartbeat Poll before declaring the Path failed and
generating a COMM FAIL SDI ## (Path 1 = SDI 88,
Path 2 = SDI 89, Path 3 = SDI 90, Path 4 = SDI 91)
Event.
If Path # Poll Rate is programmed with a value and
the central station does not acknowledge the poll
from the control panel, keypads annunciate a trouble
condition. To send this event to the central station,
refer to the Comm Fail prompt in Section
2.13.2
Panel-Wide Relays on page 81.
