Battery Circuit Calculations
Before selecting the battery, it is important to determine the minimum size batteries for standby and alarm times desired for each
application and SLC current draw.
If the wrong batteries are installed in a specific application or incorrect current draw used, the
proper standby and minimum alarm time will not be present.
The battery circuit is rated for 8 to 55 AH batteries and will operate the panel alarm for at least 24 hours and 5 minutes. The
cabinet will house up to two (2) 8 AH or two (2) 18 AH batteries.
Please use the worksheets listed below to calculate the battery size and current draw required for each application and the SLC:
