Refer to Keypad Programming of Path # IP Address, Path # Port Number, and Path # Poll Rate on page 132.

Path # Poll Rate

Default: 0

Selection: 0, 5 to 65535 sec

0Disables the heartbeat poll (not recommended, refer to the first Important Note that follows).

5 to 65534	Enables the poll rate for the amount
	of time programmed here.

65535	The maximum number of 65535 sets
	the poll rate to once every 24 hr.

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.

In order to supervise the virtual link between the control panel and a central station receiver over a network path, you must set Path # Poll Rate to a non-zero value.

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 TROUBLE SDI ## for SDI 88

(Path 1 = SDI 88, Path 2 = SDI 89, Path 3 = SDI 90, Path 4 = SDI 91) Event. For SDI 92 (Path 1 = SDI 92, Path 2 = SDI 93, Path 3 = SDI 94, Path 4 = SDI 95) 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 Trouble prompt in Section 2.12.2 Panel-Wide Relays on page 81.

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

1.Refer to Figure 1 on page 7 to access Keypad Programming and navigate to the ENHANCED COMM option. Press [ENT].

2.The keypad alternates between COMMUNICATIONS> and ENHANCED> YES. Press [NEXT] to access the Path 1 - 4 prompt.

3.Enter the path number you wish to configure and press [ENT]. The currently configured IP address shows.

4.Press [ENT] to change the IP address. An invisible editing cursor is enabled for the first byte.

5.The [PREV] button acts as a [Backspace] key. Press [PREV] to delete the characters of the byte, and then enter the new byte numbers, or press [NEXT] to move to the next byte.

The keypad only accepts byte numbers valid for the current prompt.

6.Repeat Step 5 to enter the correct numbers for each byte.

7.Press [ENT] to save the changes.

When the keypad reads PARAMETER SAVED, your selection is configured.
