Emergency Mustering

Martyn’s Law: Lockdown, Invacuation and Compliance, Built In

Martyn’s Law changes how venues respond to threats. It’s no longer just about evacuation, but knowing when to lock down and keep people safe inside. Synel provides the access control, lockdown, and occupancy visibility needed to meet both Standard and Enhanced tier requirements, with clear records to demonstrate compliance.

The reality today

Fire safety trained everyone to evacuate. Martyn’s Law sometimes requires the opposite, keeping people inside, away from an external threat. Your systems can open doors, but can they lock down zones? Can you account for everyone instantly? Can you prove compliance to a regulator? The legislation is coming. The question is whether you’re ready.

The Solution

Synel Access enables lockdown and invacuation as part of your access control strategy. Zones can be secured instantly, occupancy is visible in real time, and every action is logged automatically to provide the auditable evidence required under Martyn’s Law.

Lockdown Capability

Zone-based invacuation keeps people safe inside when the threat is outside. Precise control over which doors lock.

Know Who's Inside

Real-time occupancy distinguishes staff, visitors, contractors. Instant roll-calls for emergency services.

Prove Compliance

Complete audit trails document every security action. Evidence ready for the regulator.

About Martyn's Law Compliance

Martyn's Law (the Terrorism Protection of Premises Act) places a legal duty on venue operators to protect the public from terrorist attacks. Fire safety gets people out—Martyn's Law sometimes requires keeping them in. Synel provides the lockdown, invacuation, and access control infrastructure to meet both Standard and Enhanced tier requirements.

Two Tiers of Compliance

Standard Tier (200-799 capacity) requires effective evacuation, invacuation, and lockdown procedures with staff training. Enhanced Tier (800+ capacity) requires physical access control, CCTV integration, documented security plans, and more rigorous measures. Synel's platform addresses both tiers.

Lockdown and Invacuation

While fire systems open doors, Martyn's Law often requires keeping them shut. If a threat is detected outside, Synergy Access can initiate an invacuation—locking perimeter doors while allowing internal movement, or isolating specific zones to contain a threat. Zone-based lockdown gives you precise control over which areas lock and which remain accessible.

Real-Time Occupancy

Emergency response requires knowing exactly who's in the building. Synel's dashboard provides real-time occupancy distinguishing between staff, visitors, and contractors. In an incident, the system generates instant roll-call lists for emergency services—essential information delivered in seconds, not scrambled together from paper records.

Alert Communication

The system can trigger alerts via mobile app to all registered users, instructing them to move to safe zones rather than evacuating to an external assembly point that might be unsafe. Different scenarios require different responses—the system supports multiple emergency protocols.

Enhanced Tier: Physical Security

High-capacity venues need hardened perimeters. Synel provides the physical access control—barriers, turnstiles, biometric readers—required to restrict entry to authorised personnel. CCTV integration provides visual verification of access events, meeting Enhanced Tier security requirements.

Audit Trails for the Regulator

The SIA regulator requires documented evidence of security measures. Synel provides complete, searchable audit trails of who accessed the site and when. Every door event, every lockdown drill, every security action logged and available for inspection.

Training and Competence Records

The system can track staff training records—ensuring security personnel have current certifications before granting access to control rooms or secure zones. Qualification expiry alerts prevent gaps in compliance. Competence is documented, not assumed.

Why This Matters Now

Martyn's Law is coming into force with corporate HQs and public buildings preparing for 2027 compliance deadlines. Non-compliance carries significant legal liability—for multi-site operators, a single breach can expose the whole organisation. The time to prepare is now, not when the deadline arrives.

Emergency Mustering FAQs

Common questions about emergency mustering answered.

What is Martyn's Law and how does it affect my business?

Martyn's Law (Terrorism Protection of Premises Act) requires venues to have protective security measures.

Standard tier (200-799 capacity) requires documented procedures for evacuation, invacuation and lockdown. Enhanced tier (800+) requires physical access control, security measures and compliance with SIA requirements.

Synel solutions provide the real-time headcount, access control and audit trails needed for compliance.

What is the difference between lockdown and invacuation?

Fire evacuation gets people out. Lockdown and invacuation keep them safe inside.

Invacuation moves people to interior safe zones away from an external threat, such as a chemical spill or hostile person outside. Lockdown secures perimeter doors while potentially allowing internal movement, or isolates specific zones to contain a threat.

Martyn's Law requires venues to have procedures for all three scenarios. Synel's access control can execute any of these protocols automatically.

How does emergency mustering work?

Emergency mustering provides instant roll call during evacuations. When a fire alarm activates, the system generates a real-time list of everyone on site based on access control and clocking data.

Fire marshals can mark individuals as safe using mobile devices or muster point readers. A central dashboard shows who is accounted for (Safe), who has not checked in (At Risk), and last known locations.

This replaces paper-based roll calls with real-time, accurate headcount data.

Can access control integrate with fire alarm systems?

Yes. Synel access control systems connect directly to building fire panels via the Adam Link controller.

Upon alarm activation, the system automatically unlocks designated doors, gates and turnstiles. Power is cut to magnetic locks, ensuring they fail-safe (unlock) instantly.

The system also generates instant roll call reports showing who is on site, supporting fire safety compliance and speeding up evacuation accountability.
