Bosch Appliances D9412GV2 manual Path # Ack Wait, Control panel powered up, Heartbeat Poll sent

D9412GV2/D7412GV2 Program Entry Guide 6.0 GV2AUX

EN 137

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 receiver.

1 - Control panel powered up											6 - No acknowledgment, Heartbeat re-sent, retry
2 -	Heartbeat Poll sent												#2
3 -	Acknowledgment received										7 -		Path declared failed
4 - Second Heartbeat Poll sent											8 -		10-sec interval
5 - No acknowledgment, Heartbeat re-sent, retry #1											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 expires. 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 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.

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. This prompt is applicable to SDI transmitted events and Heartbeat Polls. Entries are made in one-sec increments.

If using IP Addresses as the communication means for UL 864 Commercial Fire applications, this parameter cannot be zero (0).
