4.2 Battery Capacity Calculations

Maximum Battery recharge time does not exceed 72 hours to satisfy EN50131-6.
Total system current (including panel and auxiliary equipment) must not exceed 610mA (panel + Aux + bell +
K+).
In the event of mains failure EN50131-1:2006+A1:2009 specifies that a stand-by battery should be able to
power the system for a non-alarmed period of 12 hours, providing that the prime power source fault is
notified to an alarm receiving centre. The typical Local Authority specified maximum bell alarm period is 15
minutes.
Non-alarmed condition 11 hrs 45mins = 11.75Hrs:
