App Description

This app comes with a tool for calculating voltage drop for fire alarm circuits as per the fire alarm code.

Voltage drop calculations are required by the fire code. Voltage drop calculations are prepared for the notification appliance circuits (NAC) as part of the fire alarm system design.

These calculations assure that the devices on the system are supplied with electrical power within the operating voltage range.

Maximum voltage drop of 4.4V, as per the code, is used in the calculations.

This app is developed and tested for all sizes and versions of iOS devices including iPhone and iPad.
