Frequently Asked Questions
What fire alarm resources does EngineersUniverse offer?
EngineersUniverse offers iOS apps for NFPA 72 system design, smoke detector spacing (Section 17.7), heat detector placement, NAC voltage drop calculations, SLC/IDC loop wiring, addressable panel configuration, battery standby calculations, and NICET Level I–IV exam prep. We also publish Kindle reference books on fire alarm design.
What is covered in the NICET exam prep apps?
Our NICET fire alarm prep apps cover all four NICET levels for fire alarm systems technicians and fire alarm systems designers — system fundamentals, NFPA 72 code knowledge, inspection and testing (Chapter 14), wiring methods, battery calculations, and practical troubleshooting scenarios.
Is there a free fire alarm 3D viewer?
Yes. The Fire Alarm 3D Building Viewer (in the Fire Alarm Studio) renders a complete commercial building with smoke detectors, heat detectors, pull stations, notification appliances, strobes, fire alarm control panels, and SLC/NAC wiring — all viewable and filterable by floor and circuit.
Which NFPA 72 chapters are covered?
Our tools and books cover NFPA 72 Chapter 10 (fundamentals), Chapter 14 (inspection, testing, maintenance), Chapter 17 (initiating devices — smoke, heat, CO), Chapter 18 (notification appliances), Chapter 21 (emergency control functions), Chapter 23 (protected premises), Chapter 24 (emergency communications), and Chapter 26 (supervising station systems).
