Upgrading the firmware can involve the following actions:
• Backing up the database from each panel
• Updating the panel firmware (Application only)
• Updating the panel firmware (OS + Application)
IMPORTANT: Recommend to back up the database before and after the firmware
upgrade.
Planning for the Firmware Upgrade
Note: The Secondary panels must be upgrade first in any order and then upgrade the
Primary panel last.
The Secondary panel Firmware upgrade through panel web page is not
recommended. Refer the below two sections to upgrade the Secondary panels.
For primary panel, plan
5-7 minutes (approximately) to upgrade the Application only
and for OS + Application plan for 10 to 15 minutes (approximately). In order to
reduce the time required to install this version on your “Secondary” panel, each
panel can be removed from the loop and configured as a "Primary" panel (discon-
nect the RS-485 before making it a Primary) by following these steps:
RS-485 Drop line:
Step 1. Configure Secondary panels as Primary and manually “Reboot”
Step 2. Upgrade the firmware
Step 3. Configure the panels back to Secondary and manually “Reboot”
Step 4. Upgrade the Firmware in the Primary
Step 5. Confirm Secondary panels are line with the Primary
Note: If a Secondary panel doesn’t come on line with the primary perform a manual
“Reboot” of the Secondary panel.
Ethernet Virtual Loop (EVL):
Step 1. “Unregister” the Secondary panels
Step 2. Configure Secondary panels as Primary and manually “Reboot”
Step 3. Upgrade the firmware
Step 4. Configure the panels back to Secondary and manually “Reboot”
Step 5. "Re-register" Secondary panels manually in the Primary panel
Remember to return their configuration back to a downstream panel once the
upgrade has been successfully completed.
The firmware and Operating System (OS) can be downloaded from the Honeywell
Download Center at the following site:
