Calculations:
1. ______________mA X .001Amp/mA X __________________ hours: ________________ Ah standby Amp-hours
Total standby
current
2. ___________mA X .001Amp/mA X ____________ minutes X .0167 hours/min _____________ Ah alarm Amp-hours
Total alarm Conversion
current factor
3. ___________mA X .001Amp/mA X ____________ seconds X .000278 hours/sec ___________ Ah Active Amp-Hours
Total active
current
4. Standby Amp-hours + Alarm Amp-hours + Active Amp-hours = Minimum battery power required
________________ + ______________ + ______________ = _______________Ah
5. Minimum battery power required X Battery capacity derating coefficient = Total standby battery required
___________________________ X ____________________________ = _____________________Ah
