18.0 Appendix F: Power Supply and
Battery Calculations
Use the form below to determine the required secondary power supply (batteries).
IMPORTANT NOTICE
The main AC branch circuit connection for Fire Alarm Control Panel 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 17.0 Appendix E: Specifications on page 101 for specifications.
