Guidance on The use of Fire Detection and Alarm systems for lockdown

This guidance explains how existing FD&A infrastructures can be used to support both traditional evacuation for fire and invacuation/lockdown for non-fire threats (e.g., intruder, violent incident, flooding, nearby external hazard), with emphasis on European practice, standards, and regulatory contexts. It is aimed at regulators, authorities having jurisdiction (AHJs), premises managers, designers, installers, and emergency planners across sectors (education, healthcare, critical infrastructure, corporate, public buildings). It does not prescribe a single operational plan; duty holders must risk-assess and define site-specific priorities and procedures, including the rare event of simultaneous fire and lockdown signals.
