Appendix B: Battery Calculations (Selection Guide)
Use the form below to determine the required batteries.
The main AC branch circuit connection for the Fire Alarm Control Unit must provide a dedicated
continuous power without provision of any disconnect devices. Use #12 AWG wire with 600-volt
insulation and proper over-current circuit protection that complies with the local codes.

Multiply (C) by 1.20 to derate battery.
Note: Batteries BA-104 (4.0AH) and BA-1065(6.5AH) fit into the backboxes; all larger
batteries such as BA-110(10AH) and the BA-117(17AH) require an external battery
box.
