Wiring for extending battery standby time and providing
additional auxiliary current output
If the module is to be connected to a control panel to increase stand by time, refer to the
appropriate control panel's Installation and Operation Guide to calculate the total battery
Ampere-hours (Ah) required for your system. The recharge time cannot exceed 48 hours for UL
listed applications. Once satisfactory recharge time, standby time, Ampere-hour, and auxiliary
current values are identified, determine the combination of batteries required for your
application using the following table.
