programmed in the iCOM/iCOM-E. If the first attempt fails, the panel uses the Net Setup String to
send the messages to the backup receiver.
Note: If NET Backup and UL AA are enabled, the panel only sends the S72 (WARNING:
NETWORK TROUBLE) message after the first series of network message attempts fails.
Note: If you are using a non-DMP network device and an iCOM/iCOM-E, use the non-DMP
device as the backup device. If not, the Net Setup String overrides the IP Address of the
iCOM/iCOM-E and is not used for the non-DMP network device.
Retry Time: Enter the number of seconds (3 to 15 seconds) the panel should wait before retrying to
send a message to the receiver if an acknowledgment was not received. The panel retries as many
times as possible for a period of one minute before sending a network trouble message. For example,
if Retry Time is set to 15, the panel retries four times. The default Retry Time is 5 seconds.
Net Backup Enable: Check the Net Backup Enable checkbox to enable Net Backup and require panel
messages to be sent to a backup IP Address if the messages fail to communicate to the remote
(primary) IP address. Leave the box empty to disable Net Backup. For more information about the
Net Backup feature, refer to Host/Net Backup Examples in the help file.
When Net Backup is enabled and the J23 jumper on the XR500 panel is set to R, panel messages are
sent through the RS-232 serial port. Refer to the XR500 Series Installation Guide (LT-0681), or the
XR2500F Installation Guide (LT-0759).
Note: Second line programming is available for dialer communication types such as CELL or DD
to backup network communications.
Supervised Backup Enable: Check the Supervise Backup Enable checkbox to enable supervised
communication and send checkins to the network Central Station receiver for the Network Backup.
Leave the box empty to disable supervised communication.
Programming options for supervision of Network Backup is provided by the same options used by the
Communications Type programming for UL AA, Check In Time, and Fail Time. If Substitution Code is
enabled, then it is automatically enabled for Network Backup. When Supervise Backup is enabled, Net
Trouble only displays on the keypad if both primary and backup IP address communications fail.
UL AA Enable: Select the box to enable UL AA Mode. UL AA involves check-in reports. Check-in
reports are a method of supervising the panel communication with the receiver. To be UL AA
compliant, panels must check-in with the receiver every 6 minutes when armed. By default, UL AA is
not enabled.
The SCS-1 or SCS-1R Receiver verifies that the next Check-in report is received at the appropriate
time. SCS-1 version 805 or higher firmware is required in the SCS-1 Receiver. When UL AA is
enabled and the check-in fails after one minute, the panel sends a WARNING: NETWORK TROUBLE
(S72) report on the 2ND LINE. The next time the NET report is successfully sent, the panel sends a
NETWORK RESTORED (S73) report over the 2ND LINE.
Note: Network Trouble, Network Fail Notification, is automatically enabled when UL AA is
enabled. Network Trouble allows the panel to detect a failure of the primary network and send
an S72, Network Trouble message, through the DD if it is programmed as the second line.
When the primary network restores the panel sends an S73, Network Restored, message.
Disarm Check-in: If you enable UL AA, this field displays. Enter the number of minutes, from 1 to 6
or R, between disarmed check-in reports. If any area is armed, the report is automatically sent every
6 minutes.
Enter R in the Disarm Check-in field to program the panel to send the check-in report at random
times, but always between 5 to 60 minutes.
