Lockdown Alert System Built for
Schools Sixth-Forms Colleges Universities
A school lockdown alert system that puts clear, full-screen instructions on every classroom and staff computer at once.
Why Emergency Communication Is Challenging in Education
Education environments range from small classrooms to large, multi-building campuses. During an incident, traditional alert methods often fail to provide clear, actionable guidance to everyone at the same time.
Fire alarms don’t explain what to do
Alarms signal danger but provide no instruction on the correct response.
Tannoy systems are unclear or missed
Audio announcements are often lost in busy corridors and large spaces.
Different audiences need different guidance
Students, staff, and visitors require different levels of clarity.
Complex education environments are difficult to coordinate.
Multiple buildings make consistent communication challenging.
Information becomes inconsistent
Without a single system, messages can be delayed or conflicting.

to deliver clear on-screen instructions across classrooms, offices, lecture halls and shared spaces.

PopAlert is built to operate reliably across the full range of education spaces — from individual classrooms to large, multi-building campuses.
Visual alerts ensure instructions are delivered clearly in both busy and quiet environments, supporting calm, coordinated responses without relying on audio announcements alone.
Why Traditional Methods Aren’t Always Enough
Emergency communication systems like PA announcements, emails, or sirens each serve a purpose — but they often lack clarity, consistency, or guaranteed visibility.
PopAlert was designed to close those gaps.

School Lockdown Alert System: FAQs
What is a school lockdown alert system?
It’s how a school tells everyone on site, instantly, that a lockdown has started and what to do. PopAlert does this with a full-screen instruction on every connected classroom computer, staff PC and corridor screen, plus a distinct alert tone that can’t be confused with the fire alarm.
Do we still need a lockdown alarm?
PopAlert works alongside lockdown alarms such as Alertex, which our sister company A-Squared Alarms installs as school lockdown alarm systems. Many schools use an audible alarm for outdoor areas and PopAlert to carry clear instructions indoors. See how one independent school in Essex did exactly that.
How does the cost compare with a hard-wired lockdown alarm?
PopAlert uses the computers and screens you already have, so there’s no cabling or sounders to install in every building. On one 90-acre campus, a hard-wired indoor alarm was estimated at £85,000 or more. Contact us for a quote for your site.
Is PopAlert suitable for primary schools?
Yes. Messages are written in advance in calm, age-appropriate wording, so staff never have to compose instructions under pressure. Many primary schools run staff-only drills first.
Does PopAlert help with Martyn’s Law?
Schools with 200 or more people on site will need procedures for evacuation, invacuation, lockdown and communication. PopAlert is a practical way to deliver the communication part. Read what Martyn’s Law means for schools.
Can we use PopAlert for lockdown drills?
Yes. Scheduled test alerts and drill mode let you practise regularly. Our step-by-step lockdown drill guide shows how.
