Calculations

The articles in this section explain how different calculations work or provide additional context to calculation-related concepts in FireBIM.

📄️ Voltage Drop Calculation Basis

Voltage drop calculations are based upon the load, cable resistance, and cable length for each device on the circuit.

📄️ Battery Calculation Basis

Battery calculations are based upon the current draw of connected devices and the minimum operation time in standy and alarm modes.

📄️ How Building Angle Affects Calculations

The Building Angle setting offsets the axes along which cable length calculations are performed, which can significantly impact several figures in your project.
