15.0 Appendix D: 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 of alarm as a multiplier figure.
 Using the Mircom MPD-65P 2-wire photoelectric smoke detector. See Device Compatibility Guide LT1007.
Total Current Requirement:ALARM (B)______ Amp. (Value obtained from column B)
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 for FA-300 Series. Indicating Circuits must not to exceed 5 Amperes.
Battery Selection: Multiply (C) by 1.20 to derate battery.
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 Appendix A for specifications.
