Maintenance
A battery set (24V) that has enough capacity to properly operate the system for 24 hours standby and 30
minutes alarm per UL864 / ULC-S527 or as otherwise required by local codes and the AHJ must also be
connected to the control panel. These batteries do lose capacity with age. Batteries must be replaced when they
fail to provide the control panel with the required standby and alarm power or after 4 years, which ever
happens first. These batteries must be checked for performance at least twice a year or more often, if local
requirements dictate.
When disabling an input or an output device, the application will indicate a trouble
condition.
