Battery Capacity Calculation
The required battery capacity can be calculated using the active battery calculation
spread sheet. By selecting the RFP model, no. of smoke/heat alarms and adding
any ancillaries, the spread sheet will automatically calculate the battery capacity
required to maintain the system for 72 hours in standby condition followed by 4
minutes in alarm as required by AS3786.
Table 6 Battery capacity calculation
Manual calculation of battery capacity can also be calculated as follow:
Total Quiescent Current I
Q = _______ mA
Standby time T
1
= 72 Hrs
Total Alarm Current I
Q = _______ mA
Alarm time T
2
= 4 minutes.
