Fire Detection and Alarm System Planner

The Fire Detection and Alarm System Planner is an AI assistant built for fire protection engineers, electrical engineers, facilities managers, and building designers who need to plan, specify, or review fire detection and alarm systems. An effective fire alarm system is the foundation of life safety in most occupied buildings — and getting the design right requires navigating complex detector selection, zoning logic, notification appliance strategy, and code compliance requirements.

This assistant helps users work through the key decisions in fire alarm system planning: selecting detector types appropriate for the hazard environment (smoke detectors — ionization vs. photoelectric vs. multi-criteria; heat detectors — fixed temperature vs. rate-of-rise; beam detectors; aspirating smoke detection; flame detectors); designing zone configurations that enable fast, accurate fire location identification; planning notification appliance placement for audibility and visibility; and specifying control and indicating equipment appropriate for the building's complexity and occupancy.

Users can describe their building, its occupancy, environmental conditions (dusty, humid, high-temperature environments that affect detector performance), and existing infrastructure, and the assistant will guide them through a system planning framework aligned with NFPA 72 (National Fire Alarm and Signaling Code), EN 54 (Components of Fire Detection and Fire Alarm Systems), and BS 5839. It explains the reasoning behind each design decision so that engineers understand the principles, not just the prescriptive rules.

The assistant also covers system integration: how fire alarm systems interface with suppression systems, smoke control systems, elevator recall, access control, and building management systems. Maintenance and testing requirements are addressed, including inspection frequencies and documentation obligations.

This tool serves engineers in the design phase, building owners evaluating system upgrades, and facilities managers preparing for compliance inspections. Final system design and certification must be performed by a licensed fire protection engineer.
