School lockdown alarm system and emergency response
A lockdown system isn't just about locking doors - it only works if staff and pupils know what to do and can act fast when it matters. A dedicated alert and clear procedures ensure everyone stays safe and knows how to respond.
What a good lockdown procedure should cover
A school lockdown plan isn’t just about hardware - it’s about safety, clarity and calm under pressure. A good procedure ensures that if a threat arises, everyone knows exactly what to do, where to go, and how to stay safe until the “all clear.”
Lockdown Alarm
A clear signal separate from the fire alarm, so staff know immediately to lockdown (not evacuate).
Protocol for Lockdown
Who triggers, where people go (classrooms / safe zones), where doors/windows are locked.
Account for Everyone
Pupils, staff, visitors (including contractors), plus provisions for people with special needs.
Communication Plan
Internal alerting, contact with emergency services, and a way to notify parents and guardians.
Strengthening your school's site security
Perimeter security and external access control
A secure perimeter is the first line of defence for any school. Locked gates, controlled pedestrian entry points and monitored access prevent unauthorised individuals from entering your site. We install gates, fencing, access-controlled entrances and integrated alerts for forced entry attempts.
Securing windows and ground-floor entry points
Ground-floor windows and external doors are the most common intruder access points. We secure vulnerable openings with reinforced hardware, locks, sensors and monitoring so that unauthorised entry is detected and prevented.
24/7 Intruder alarm monitoring
Your school is most vulnerable after hours. Our monitored intruder alarm systems alert you and the monitoring centre immediately if a break-in is attempted – providing protection during evenings, weekends and holidays when the site is empty.

Site Survey & Vulnerability Check
Before we install any lockdown or access-control system, we carry out a full on-site survey to check your school’s security landscape. From perimeter fences and gates to doors, windows and potential weak spots.
We assess entry and exit points, external access routes, vulnerable windows or ground-floor openings, lighting, escape routes and general site layout.
we then design and tailor your lockdown setup around the findings.
We Offer Visitor Management & Controlled Entry Solutions
A modern visitor-management system ensures that everyone entering the school is logged, checked and issued a temporary pass or badge – so you always know who is on site. It prevents unauthorised access, keeps accurate digital records and provides a live roll-call for all staff, pupils and visitors – especially useful during lockdowns.
Improve your school security - now and for the future
Our lockdown systems are built for every type of education setting - from primary and secondary schools to colleges and sixth forms, and through to universities. Whether you’re securing a single building or a larger multi-building site, the system scales easily and integrates with your existing access control and alarm setup.
