In today’s climate, ensuring the safety of students, staff, and visitors in educational and public settings has never been more important. While fire alarms are standard, many sites are now also adopting lockdown alarms — systems designed to protect and alert building occupants in the event of an intruder or other critical threat.

At Diamond Systems, we offer a wireless lockdown alarm system, a simple, robust solution that’s quick to install and easy to operate — with no need for complex wiring or disruptive building work.

What is a Lockdown Alarm?

A lockdown alarm is a dedicated system used to alert people inside a building to initiate a lockdown procedure. Much like a fire alarm prompts evacuation, a lockdown alarm prompts people to stay indoors, secure entry points, and await further instructions.

Our Lockdown Alarm System uses wireless mesh technology, meaning alarm units placed throughout a site can communicate with each other and a central control panel — even if one device goes offline.

Lockdown alarm devices include:

• A call point (similar to a break glass fire point) to activate the system
• Visual and audible alerts via integrated sounder and beacon (optional)
• The option to send mobile notifications to up to 50 designated contacts
• Integration with public address (PA) systems or external autodiallers

Who are lockdown alarms for?

While originally developed for schools, this system is ideal for a wide range of premises, including:

• Primary and secondary schools
• Nurseries and playgroups
• Universities and colleges
• Healthcare clinics and GP surgeries
• Council offices
• Community centres and places of worship
• Leisure centres and libraries
• Retail and commercial premises with public access

Whether you manage a single building or a large campus, this system provides peace of mind with its ease of use, reliability, and minimal disruption during installation.

Why Wireless?

One of the biggest challenges with retrofitting security systems is cabling. Our lockdown alarms eliminate this issue:

• No need to drill through walls or ceilings
• Reduced installation time
• Easier relocation if your layout changes
• Battery-powered or mains options available

Optional Enhancements

Need a little more from your system? You can add:

• A central control panel to identify which zone triggered the alert
• Auto-diallers to notify emergency services or senior staff
• Integration with CCTV or access control systems

If you’re considering a lockdown solution for your premises, our team can help design and install a system that meets your site’s specific needs — all with the high standard of care and discretion you expect from Diamond Systems.

The New Code of Practice for Fire Detection and Fire Alarm Systems is Now in Force

The updated BS5839-1:2025 standard for fire detection and fire alarm systems in non-domestic premises was published on 29th April 2025 and is effective immediately.

At Diamond Systems, we pride ourselves on not only staying ahead of industry changes — but also understanding what they really mean for our clients. Here’s a closer look at what’s changed and our take on why it matters.

---

The Key Changes at a Glance:

🔸 Risk-Based Design Takes Centre Stage
The objective of an L2 system where there is a sleeping risk has been further clarified.

🔸 Higher Standards for Installation
New siting rules for detectors and stricter expectations around functional earthing emphasise precision and resilience in installation quality.

🔸 Stronger Focus on Maintenance and System Lifespan
The updated standard tightens the rules around service intervals, redundant device management, and remote maintenance options — with cybersecurity now firmly in focus.

🔸 Greater Scrutiny of Alarm Transmission
Alarm transmission must now meet tougher performance, resilience, and cyber safety requirements.

---

Our Take on the Changes

At Diamond Systems, we believe BS 5839-1:2025 is more than just an update — it’s a shift in mindset across the industry.

1. Designs Must Be Truly Risk-Based

The change:
L2 system requirements now stress protection of both escape routes and high-risk areas.

Our view:
This demands deeper fire strategy knowledge. Designers can’t just apply boilerplate layouts anymore — systems must align with each building’s specific risks and evacuation plans. It’s a major step toward smarter, safer designs.

---

2. Quality of Installation is Under the Spotlight

The change:
Stricter rules on siting detectors, avoiding obstructions, and ensuring correct earthing.

Our view:
The industry is finally tackling poor workmanship. Installers need to think like designers, not just box-fitters. Expect more scrutiny on every cable, detector, and termination.

---

3. Maintenance is No Longer a Ticking Exercise

The change:
Clearer guidance on servicing, managing redundant devices, and enabling remote inspections securely.

Our view:
Compliance is now about continuous evidence, not just a sticker on the panel. Clients will need trusted partners who can offer full lifecycle compliance and cybersecurity resilience — not just annual testing.

---

4. Alarm Transmission Must Be Rock-Solid

The change:
Tougher requirements for how alarm signals are monitored, transmitted, and secured.

Our view:
Gone are the days of “plug and pray” diallers. The standard recognises that alarm transmission is mission-critical and must be treated with the same engineering rigour as the fire system itself.

On April 3, 2025, the UK government enacted the Terrorism (Protection of Premises) Act 2025, commonly known as Martyn’s Law. This legislation mandates that certain public venues and events implement measures to enhance preparedness against potential terrorist attacks. Named in memory of Martyn Hett, a victim of the 2017 Manchester Arena bombing, the law represents a significant step toward strengthening national security and safeguarding the public.

What Is Martyn’s Law?

Martyn’s Law aims to ensure that venues and events are equipped to respond effectively in the event of a terrorist attack. It introduces a tiered framework based on the capacity of the premises or event:​

• Standard Tier: Applies to venues where it is reasonable to expect that between 200 and 799 individuals may be present at the same time.​
• Enhanced Tier: Applies to venues and events where it is reasonable to expect that 800 or more individuals may be present at the same time.​

The classification determines the specific security obligations required to mitigate risks and protect attendees.

Who Will Martyn’s Law Apply To?

Martyn’s Law applies to a wide range of publicly accessible locations where people gather. If your premises or event is open to the public and falls within the Standard (200–799 capacity) or Enhanced (800+ capacity) tiers, you will likely have duties under the legislation.

Here are some examples of the types of premises and events that may be affected:

Standard Tier (200–799 capacity)

These are often smaller public venues that still pose potential risks in the event of an attack:

• Medium-sized shops, supermarkets, and retail parks
• Restaurants, pubs, and bars with significant seating
• Community centres and town halls
• Independent cinemas and small theatres
• Places of worship (churches, mosques, synagogues, etc.)
• Small visitor attractions (heritage sites, museums, galleries)
• Libraries and leisure centres
• Nurseries, primary and secondary schools (if public access and numbers meet threshold)
• Clinics and smaller healthcare centres (with large patient volumes)
• Small train and bus stations
• Hotels or guesthouses that host medium-sized events (weddings, conferences)

Enhanced Tier (800+ capacity)

Larger venues with higher footfall, often in entertainment, transport, or commercial sectors:

• Stadiums and sports arenas
• Concert halls, large theatres, and entertainment venues
• Major shopping centres and department stores
• Universities and larger college campuses
• Large hospitals and healthcare facilities
• Airports and major ferry ports
• Major bus and railway stations (city hubs)
• Conference and exhibition centres
• Large places of worship (cathedrals, megachurches)
• Big hotels and resorts (especially those hosting large public events)
• Major visitor attractions (zoos, theme parks, historic castles, national museums)

Venues that are not permanently staffed or only occasionally open to the public (such as private clubs, office-only buildings, or residential areas) are generally outside the scope — but grey areas may exist, so a site-specific risk assessment is still recommended.​

Key Requirements for Businesses

Standard Tier Responsibilities:

Key duties:

• Basic terrorism risk assessment
• Staff awareness and training
• Simple procedural plans (e.g., locking doors, evacuation procedures)

​Enhanced Tier Responsibilities:

All Standard Tier Measures, plus:

• Public Protection Measures: Implement additional measures, as far as reasonably practicable, to reduce both the vulnerability of the premises or event to an act of terrorism and the risk of physical harm to individuals. Examples include bag search policies, CCTV monitoring, and vehicle checks.​
• Documentation: Maintain a documented assessment of the public protection procedures and measures in place, and provide this to the SIA.​
• Senior Individual Designation: If the responsible person is not an individual, designate a senior individual responsible for ensuring compliance with the Act.​

All measures are subject to the principle of “reasonably practicable,” taking into account the specific circumstances and resources of each venue or event.

The Inspiration Behind the Law: Figen Murray’s Advocacy

Figen Murray, the mother of Martyn Hett, has been instrumental in the development and promotion of Martyn’s Law. Following the tragic loss of her son in the Manchester Arena attack, Figen was surprised to discover the lack of mandatory security measures at public venues. This realization led her to campaign tirelessly for legislative change, resulting in the inception of Martyn’s Law.

Figen’s efforts have been recognized nationally; she was awarded an OBE in 2022 for her services to counter-terrorism. Beyond legislation, she engages in educational talks across the UK, aiming to raise awareness about the importance of security and the human impact of terrorism

Implementation Timeline

The government has established a 24-month implementation period from the date of Royal Assent to allow businesses and organizations adequate time to understand and comply with the new requirements. During this period, the SIA will develop and publish statutory guidance to assist duty holders in meeting their obligations.

How Diamond Systems Can Support Your Compliance

With over 35 years of experience in life safety and security, Diamond Systems is well-equipped to assist organizations in meeting the requirements of Martyn’s Law. Our services include:​
