Solve 20 practice problems on conductor ampacity, overcurrent protection, and voltage drop for notification appliance circuits (NACs), showing each step of the calculation.
Explain in writing why Article 760 governs fire alarm power-limited circuits and how Article 300 wiring-method rules still apply.
Your checkpoint
A 2-page Article 760/725 comparison table plus 20 worked NEC calculation problems with a short error log listing every miss and its code clause.
National Electrical Code (NFPA 70) requirements for fire alarm circuits & National Fire Alarm and Signaling Code (NFPA 72) fundamentals

Map each NFPA 72 circuit performance class (Class A, B, C, D, E, X, N) to its survivability and annunciation characteristics in a comparison grid.
Cross-reference NFPA 72 pathway survivability Level 0-4 requirements against NFPA 70 Article 760 wiring methods.
Answer 25 mixed questions on circuit class, pathway survivability, and shared-function requirements, and cite the governing clause for each answer.
Your checkpoint

National Fire Alarm and Signaling Code (NFPA 72) fundamentals
Read NFPA 72 Chapters 14, 17, and 18 and outline detection technology selection criteria for spot smoke, beam smoke, air-aspirating, heat, and flame detectors.
Compute detector spacing and coverage for a 60 ft by 40 ft room using the NFPA 72 spacing formula and the 0.7 times spacing-to-wall rule.
Draft a justification memo selecting detection type for a warehouse, a data center, and a commercial kitchen.
Complete 30 practice items on detector spacing, mounting, and performance-based design triggers.
Your checkpoint
A spacing calculation worksheet for three sample rooms plus a one-page detection selection memo with clause citations.
National Fire Alarm and Signaling Code (NFPA 72) fundamentals & Initiating devices, notification appliances, and circuit design
Read NFPA 72 Chapter 18 notification appliance requirements and Chapter 21 emergency control functions, and list audibility, intelligibility, and visible appliance coverage rules.
Calculate NAC loading and voltage drop for a 24 VDC circuit with 30 appliances at 0.05 A each over 250 ft of 14 AWG, and determine whether the design passes.
Design a complete signaling line circuit and NAC layout for a two-story, 20,000 sq ft building, including device counts and candela selection.
Compare addressable and conventional initiating device circuit topologies against NFPA 72 supervision requirements.
Your checkpoint
A complete design package for the 20,000 sq ft sample building: riser sketch, NAC voltage-drop calculation, device schedule, and candela/audibility justification.
Control equipment, power supplies, and standby power
Read NFPA 72 Chapter 10 power supply requirements and calculate standby capacity for 24 hours standby plus 5 minutes alarm at full load.
Size a battery bank for a stated load profile and verify recharge time against the 24-hour recharge requirement.
Diagram a fire alarm control unit power distribution scheme showing primary supply, secondary supply, and remote power supplies.
Explain the difference between a protected premises control unit and a supervising station connection in writing.
Your checkpoint
A battery sizing calculation sheet with load profile, amp-hour result, and recharge verification, plus a one-page power distribution diagram.
Inspection, testing, and maintenance of fire alarm systems
Read NFPA 72 Chapter 14 inspection, testing, and maintenance requirements and build a frequency table for every device and system component.
Write a step-by-step test procedure for a smoke detector sensitivity test and a notification appliance audibility test.
Interpret a sample inspection report and identify three deficiencies with the required corrective action and code citation.
Practice documenting test results in a format acceptable to an authority having jurisdiction.
Your checkpoint
