What are the battery requirements for a fully loaded NFS2-3030, and how do I size the batteries?
The NFS2-3030 requires sealed lead-acid batteries with a capacity between 7 AH and 200 AH, charged by the AMPS-24/E power supply (Page 11, 15) [1].
To size the batteries for a fully loaded system, you must use the specific current draw formulas found in the power supply's documentation.
-
Identify all system components, including the CPU and up to 10 SLC loops (Page 11, 12) [1].
-
Consult the Power Supplies Calculations Table in the AMPS-24/E Manual to determine total standby and alarm current (Page 34, 61) [1].
-
Verify the physical mounting location; CAB-4 series backboxes can only house up to two 26 AH batteries internally (Page 16) [1].
-
If the calculated requirement exceeds 26 AH, the batteries must be installed in a separate enclosure such as a BB-100 or BB-200 (Page 20) [1].
