Figure 8: Poll Rate Timeline

1 - Heartbeat Poll sent
2 - Acknowledgment received
3 - Second Heartbeat Poll sent
4 - No acknowledgment, Heartbeat re-sent, retry #1
Example of Retry Count:
An acknowledgment of the heartbeat was not
received within 10 sec. The control panel sends the
next Heartbeat Poll after the first 10-sec ACK wait
period. If the central station does not acknowledge
this Heartbeat Poll, the control panel continues to re-
send. When the resend count is reached, the control
panel declares this path as failed (and generates the
Comm Trouble ## Event). The control panel
continues to re-send the Heartbeat Poll at the original
poll rate time until it receives an acknowledgment,
even after declaring a Comm Trouble.
When the control panel receives acknowledgment
from the central station, the control panel returns to
the normal Poll Rate (which, in this example, is 120
sec).
If more than one SDI Path is used, the control panel
handles them on a successive basis. For example, if
acknowledgment from SDI Path 1 is not received
within 10 sec (using the previous example), the
control panel moves to SDI Path 2 to send its
Heartbeat Poll (and subsequently waits for the ack)
before returning to SDI Path 1 to re-send its
heartbeat.
If Heartbeat Polls are enabled to send by
an SDI path, and the Path # Ack Wait
time is exceeded, a COMM TRBL SDI ##
event occurs. When this condition occurs,
all events routed to this path go
immediately to the backup path
destination.
Entries are made in one-sec increments.

Path # Ack Wait
Default: 13
Selection: 5 sec to 65535 sec
5 to 65535 The control panel waits this amount
of time to receive an
acknowledgment from the central
station.
Determines how long the control panel waits for an
acknowledgment from the central station after a
Heartbeat Poll or an actual event was transmitted.
When this condition occurs, all events routed to this
path go immediately to the backup path destination.
Path # Retry Count
Default: 5
Selection: 0 to 255
0 COMM FAIL RG# SDI ### Events
are not generated.
1 to 255 COMM FAIL RG# SDI ### Events
are generated after resending
Heatbeat Poll the number of times
selected for a given SDI path.
Determines how many times the control panel
resends the Heartbeat Poll before declaring a path
failure and generating a COMM FAIL RG# SDI ###
(RG # = 1 to 4, SDI ### = 88 for Path 1, 89 for Path 2,
90 for Path 3, 91 for Path 4) Event.
