## What is AlarmAmps?

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.
