1 - Control panel powered up
2 - Heartbeat Poll sent
3 - Acknowledgment received
4 - Second Heartbeat Poll sent
5 - No acknowledgment, Heartbeat re-sent, retry
No. 1
6 - No acknowledgment, Heartbeat re-sent, retry
No. 2
7 - Path declared failed
8 - 10-sec interval
9 - Additional Heartbeats sent every 10 sec until
acknowledged
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 Fail ## Event).
The control panel continues to re-send the Heartbeat
Poll every 10 sec until it receives an acknowledgment,
even after declaring a Comm Fail.
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 COMMm 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.
Although RPS and the D5200 allow Path
# Poll Rate values of 1 to 4, the control
panel interprets these entries as an entry of
5.
5 min = 300 sec
1 hour = 3600 sec
12 hours = 43,200 sec
18 hours = 64,800 sec
Path # Ack Wait
Default: 13
Selection: 0, 5 sec to 65535 sec
0
The control panel does not look for
any acknowledgment from the central
station.
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.
Although RPS and the D5200 allow Path
# Ack Wait values of 1 to 4, the control
panel interprets these entries as an entry of
5.
