17.0 Appendix E: Power Supply and
Battery Calculations
Use the form below to determine the required secondary power supply (batteries).
* Assume three Initiating Circuits are in alarm.
' Use 0.084 for five minutes, 0.168 for 10 minutes and 0.5 for 30 minutes of alarm as a multiplier figure.
Ò Using the Mircom MPD-65P 2-wire photoelectric smoke detector. See 14.0 Appendix B: FR-320 Series
Compatible Devices on page 98 for other compatible smoke detectors.
Total Current Requirement: ALARM (B)______ Amps. (Value obtained from column B)
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 16.0 Appendix D: Specifications on page 105 for specifications.
