Explore the operation of addressable fire alarm systems and how to apply NFPA 72 requirements in hotel design, with practical, hands-on design exercises and essential documentation.
Explore smoke detectors and heat detectors, including ionization and photoelectric types, combinations, and multi-criteria detectors, along with placement, environmental factors, and NFPA 72 spacing guidelines.
Air duct detectors use photoelectric technology to sample return air, trigger alarms, and shut down the air conditioning system to prevent smoke spread; NFPA 72 emphasizes supplementing fire protection system.
Explore air sampling detectors, or aspiration detectors, using an aspirator and a pipe network with a nephelometer to detect smoke early, suitable for clean rooms, per NFPA 72 17.7.3.6.
Explore audible and visible notification systems in NFPA 72 2022 alarms, including horns, strobes, and horn with strobe. Learn how paging broadcasts pre-recorded or live messages to guide evacuation routes.
Explore wiring concepts and best practices for fire alarm systems, including class A, class B, and class N networks, insulator modules, and proper routing and labeling.
Explore how to locate, interpret, and apply NFPA 72 requirements for initiation devices, notification appliances, and pathways, and understand the code’s structure, chapters, and annexes.
Annexes serve as explanatory supplements to NFPA 72 chapters, with Annex A as the most important, illustrating detector mounting, spacing guidance, and system design guidelines across Annexes B–H.
Explore the NFPA 72 2022 edition changes, including the new chapter 11 on cyber security and annex J guidance for equipment, software, data paths, and panel communications.
Identify occupancy by intended use and occupant risk under NFPA 101, guiding life-safety requirements and fire alarm design across assembly, educational, healthcare, residential, business, industrial, and storage occupancies.
Design a hotel fire alarm system by placing smoke detectors in corridors and guest rooms, using heat detectors where needed, with elevator call, NFPA 72/101 horns and strobe lights.
Explain second level fire alarm design per NFPA 72 2022, detailing smoke detectors with sounder bases, heat detectors, beam detectors, pool stations, and notification devices across wings and gym.
Learn to apply NFPA 72 design rules to locate heat and smoke detectors using listed and nominal spacing, with height, enclosure, and beam or joist adjustments.
Explore real fire alarm design projects, examining device placement, wiring layouts, and isometric drawings, with a replicable detail sheet and a calculation memory document as best-practice documentation.
Attached to this class you will find as downloadable resources generic tables for battery calculation and the hotel project calculations
***Update based on the NFPA 72 2022 & NFPA 101 2022 Edition***
Every day we see more complex constructions with more demanding requirements, which require extensive knowledge of the concepts and standards by engineers and architects for the design of fire alarm systems as well as field personnel responsible for installations and testing.
In this course you will learn the design procedures and calculations of fire alarm systems while clarifying the concepts of each component. It is designed for beginner students as well as professionals with previous knowledge in fire alarm systems.
The course uses a theoretical/practical methodology so we will be working together on a Hotel project design, where we will have to make calculations and locate the different components based on what NFPA 72 and NFPA 101 standarizes. Before working on the design we will focus on reviewing each component of a fire alarm system, how it works and interacts with other system.
What concepts will you learn in this course?
