Total Current Requirement: ALARM (B)______ Amps.
Battery Capacity Requirement:
([STANDBY (A) ______ ] X [(24 or 60 Hours) ___ ]) + ([ALARM (B) ______ ] X [

Alarm in Hr.] _____) = (C) ______AH
Main Chassis Selection: Select FX-2003-6DS or FX-2003-6DS-16LED or FX-2009(S)-12DS or
FX-2017(S)-12DS if (B) value is less than 12 Amps.
Battery Selection: Multiply (C) by 1.20 to derate battery.
Batteries: BA-110(10AH), BA-117(17AH) will fit in the UB-1024DS
BA-124 (24AH) will fit in the BBX-1072ADS/ARDS, BB-5008, or the BB-5014
BA-140(40AH) will fit in the BC-160 battery cabinet
* Assuming three initiating circuits in alarm.
♣
Use 0.084 for five minutes of alarm or 0.5 for thirty minutes of alarm as a multiplier figure.
