APPENDIX "D" - POWER SUPPLY & BATTERY CALCULATIONS (SELECTION GUIDE)
Use the form below to determine the required Secondary Power Supply (batteries).
IMPORTANT NOTICE
The main AC branch circuit connection for 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.
Refer to appendix "C" for specifications.

Total Current Requirement: ALARM (B)______ Amps.
Battery Capacity Requirement:
([STANDBY (A) ______ ] X [(24 or 60 Hours) ___ ]) + ([ALARM (B) ______ ] X [***Alarm in Hr.] _____) = (C) ______AH
Total Alarm Current: Must be 6 amperes or less. Indicating Circuits not to exceed 5 amperes.
Battery Selection: Multiply (C) by 1.20 to derate battery.
The control panel will charge up to 24AH Batteries in a separate Listed enclosure.
*** Use 0.084 for five minutes of alarm as a multiplier figure.
