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.
When sending reports to a central station
receiver over a network path, you must set
this programming prompt 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 poll rate if it
is less than 300 sec to a temporary poll
rate of 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 the
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 74.
Example of Heartbeat:
•
Path # Poll Rate
is set to 120 sec
•
Path # Ack Wait
time is set to 10 sec
•
Path # Retry Count
is set to 2
When the control panel first powers up, the first
Heartbeat Poll for Path 1 is sent and is acknowledged
in 1 sec. 120 sec after the first Heartbeat Poll is sent,
the second Heartbeat Poll for Path 1 is generated and
sent to the central station.
