What is a lockdown alarm sound?
A lockdown alarm sound is a dedicated audio warning instructing people to stay indoors, secure rooms, and remain quiet. Distinct from a fire alarm (which signals evacuation), these alerts are critical for Martyn’s Law (Protect Duty) compliance in schools, theatres, and stadiums.
What should a lockdown alarm sound like?
- Distinctly different from fire bells or sirens.
- Urgent yet calm to prevent mass panic.
- Recognisable by staff, covering all classrooms, foyers, and outdoor areas.
Pro Tip: The best systems use a unique tone followed by clear voice instructions: “Attention: Lockdown in effect. Secure all doors.”
Is a lockdown alarm legally required under Martyn’s Law?
While the law focuses on outcomes rather than specific equipment:
- Standard Duty (200-799 capacity): Must ensure effective lockdown communication.
- Enhanced Duty (800+ capacity): Requires documented procedures and proof of drills.
A dedicated lockdown system is widely considered "best practice" to meet these requirements.
What type of lockdown alarm system is best?
- Wireless Systems: Low-disruption install for schools and old buildings.
- Multi-Trigger: Activation from reception, offices, or portable fobs.
- Hybrid Alerts: Combines unique tones with clear voice commands.
