DE Fire Alarm study guide
DE Fire Alarm · Work through your exam, one topic at a time.
The Delaware Fire Alarm Contractor License credential is intended for individuals and firms that design, install, service, or inspect fire alarm systems in Delaware. The exam verifies knowledge of fire alarm fundamentals, NFPA 72 requirements, and Delaware-specific regulations. The DE Fire Alarm study guide has 9 sections and about 4,188 words.
01Fire Alarm System Fundamentals and Code Administration
This domain tests how you use NFPA 72 as an administrative and legal document: who has authority over a fire alarm installation, which edition applies, what documentation must be produced, and how the code's mandatory language is read. Delaware questions here usually combine NFPA 72 Chapter 1 with the State Fire Marshal's adoption and permitting process.
463 words, about 2 min02NFPA 72 Definitions, Chapters 1-3, and Referenced Standards
This domain tests vocabulary precision. NFPA 72 Chapter 3 definitions feed every later chapter, and Chapter 2 tells you which outside standards the code relies on.
491 words, about 2 min03Initiating Devices and Detection Principles
This domain tests device selection and individual placement. You must match the detector to the expected fire signature, then apply NFPA 72 spacing rules that are frequently more restrictive than the simple area formula.
509 words, about 3 min04Notification Appliances and Audible/Visible Signaling
This domain tests whether occupants actually receive the signal. You must know the sound pressure targets by mode, the low-frequency rule for sleeping areas, and how visible appliance intensity and mounting are selected.
488 words, about 2 min05Circuits, Pathways, and Wiring Requirements
This domain tests survivability and supervision. NFPA 72 Chapter 12 defines pathway classes and survivability levels; NFPA 70 Article 760 governs the wiring method, cable type, and separation from power circuits.
455 words, about 2 min06Power Supplies, Batteries, and Secondary Power Calculations
This domain tests whether the system keeps working when the utility fails. You need the primary supply rules, the standby-plus-alarm duration, and the arithmetic of a battery calculation including the derating factor.
448 words, about 2 min07Inspection, Testing, and Maintenance per NFPA 72
This domain tests Chapter 14. The exam wants three things separated clearly: inspection (visual), testing (operational verification), and maintenance (work that keeps the system at design performance).
413 words, about 2 min08Fire Alarm System Design, Spacing, and Coverage
This domain tests system-level design: how detection zones are organized, how coverage strategy follows the occupancy, and how building features such as ceiling height, slope, and beams change the layout. Device-level spacing rules appear here too, but applied to a whole floor plan.
457 words, about 2 min09Delaware Fire Prevention Regulations and Licensing Requirements
This domain tests the Delaware layer on top of NFPA 72: who regulates fire alarm work in the state, what must be approved before work starts, who may install and service systems, and how the state interacts with local authorities. Expect process questions rather than code math.
