Fire Alarm Calculations

Every fire alarm calculation method, worked with real numbers and every intermediate step shown — the standalone reference this program's case studies and capstone project all lean on.

Module 6 walked through when and why each calculation gets run during a real design sequence. This module is the calculations themselves — battery standby/alarm load, voltage drop, current loading, NAC loading, SLC loading, amplifier sizing, and speaker tap selection — each worked end to end with an invented but realistic device list, not just a formula stated in the abstract. Where a first attempt fails or barely passes, the fix is worked out too, because that's the part a formula alone never teaches.

This is a methods reference, not a project — the case studies later in this program apply these exact same calculations to a specific building. If you get stuck on the arithmetic here, the studio's three free interactive calculators below run the same math live.
