Battery Capacity Requirement
Battery (AH) = (Standby Current Total x Discharge Time) + (Alarm Current Total x Alarm Time)
([STANDBY (A) ______ ] X [(24 Hours) ___ ]) + ([ALARM (B) ______ ] X [Alarm in Hr.] _____) = (C) ______AH
Total Alarm Current must be
10
amperes or less. NAC Circuits must not exceed
6
amperes.
Battery Selection
Battery Size = Multiply (
C
) by 1.20 to derate battery.
See the following table for the recommended Secutron batteries for use with this panel
BAT-12V12A (12 AH) and BAT-12V18A (18 AH) will fit into the MR-401 enclosure.
To house BAT-12V26A (26 AH) and BAT-12V42A (42 AH) batteries an external BC-160 Battery Cabinet is
required.
Use of alternative batteries may result in failure of the panel to meet agency and regulatory requirements, and may result in
shortened battery life. Batteries should be tested regularly, and replaced at least every three years. If the Battery Trouble
indicator activates, obtain required service.
