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 the SDI paths. Refer to Table 3.4, Page 25.
For SDI2-2 (Path 1 = SDI 21, Path 2 = SDI 22, Path 3 = SDI 23, Path 4 = SDI 24).
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 3.14.2 Panel-Wide Relays,
page 121.
Keypad Programming of Path # Network Address, Path # Port Number, and Path # Poll Rate
D1255
1. Refer to Section 2.5.1 Keypad Programming Menu, page 12 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
network address shows.
4. Press [ENT] to change the network 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.
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.
NOTICE!
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.
NOTICE!
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.
NOTICE!
The control panel readjusts a Heartbeat Poll rate of less than 300 sec to 300 sec when online
with RPS. The poll rate returns to the programmed value after the RPS session ends.
NOTICE!
The keypad only accepts byte numbers valid for the current prompt.
