*Note: Addition of UL 985
In compliance with UL 985 edition 6, the installation of Firmware version 3.2.6 will apply the latest standards which include
recognizing panel batteries that have aged over time and are no longer capable of providing 5 minutes of alarm signalling during
a power failure for UL985 applications. These batteries must be replaced.
Once the new firmware has been applied, the panel performs frequent tests and generates a battery trouble if any test fails to
meet UL985 threshold. Battery Trouble is considered a critical alert, which will sound and must be acknowledged every 4 hours
until the condition clears (i.e., battery is replaced). Panel Battery Trouble may trigger soon after update or it may take up to 12
hours. Dealers should be prepared to address this issue when they are upgrading the customers firmware should it occur.
Firmware prior to 3.2.6 however will continue with the previous standard and may show the battery at a normal status.
