Worksheet C: CO device current load
For a system using CO devices, determine the total amount of CO signal current in milliamps required by all of the
CO devices that derive power from the battery while the panel is in CO alarm mode. Use the alarm currents on
the sounder base installation sheet for your calculations. Multiply the total amount of CO signal current by 12
hours to obtain the mAh value used in the Battery Calculation Worksheet.
