Battery amp-hours and NAC voltage drop on your phone, every step shown, 20% derate applied to the total. Unlock the PDF submittal for the AHJ. No account, no network. Stop filling out the manufacturer's spreadsheet on a laptop in the truck. AlarmAmps does the battery calculation and the NAC voltage drop on your phone — and gives you the signed PDF submittal the AHJ is going to ask for. FREE • One project, unlimited devices • Required amp-hours, with every step of the work shown • Battery recommendation from your own list • Voltage drop on one circuit, with a pass/fail against the device's minimum voltage FULL UNLOCK ($4.99, one time) • The PDF submittal sheet — project header, itemized device schedule with currents, the worked calculation, the boxed result, the voltage-drop schedule, and a signature block • Multiple projects, panels and NACs, plus booster panels • Saved device library YOU ENTER THE CURRENTS — HERE'S WHY AlarmAmps ships no device tables. You type the standby and alarm current off your own datasheet. That's not a shortcut — it's more accurate, because currents vary by model and revision, and the sheet in your hand is the truth. It also means the app never needs a network. THE DERATE IS APPLIED IN THE RIGHT ORDER The 20% is applied to the total, after summing standby and alarm — not to standby alone. Getting that backwards undersizes the battery. AlarmAmps gets it right and shows you the arithmetic so you can check it. 100% ON DEVICE No account, no network, no tracking. Not a substitute for engineered design — the designer of record is responsible for the final calculation. Not affiliated with or endorsed by NFPA. Always verify against the code edition adopted by your AHJ.

The one-time purchase is now called Submittal Pro, named for what it actually unlocks: the PDF submittal sheet, multiple projects and circuits, and the saved device library. Same purchase, same price — if you already own it, nothing changes.
