Alarms create noise.
People need direction.
When an alarm sounds, people ask the same questions: Is this real? Do we lock down or get out? PopAlert answers instantly, with the same clear instruction on every screen.
What Is PopAlert?
PopAlert is an on-site emergency alert and lockdown communication system designed for UK organisations.
It delivers instant, full-screen instructions across connected computers and screens during lockdowns, evacuations, invacuations and other critical incidents.
Unlike traditional alarms that only make noise, PopAlert provides clear, written direction — so staff know exactly what to do.
PopAlert turns alarm moments into structured response.

Frequently Asked Questions
What is PopAlert?
PopAlert is an on-site emergency alert system for UK organisations. It shows clear, full-screen instructions on every connected computer during lockdowns, evacuations, invacuations and other incidents.
Does PopAlert need the internet?
Not to deliver alerts. Alerts travel over your internal network from the on-site control unit. A controlled outbound connection is only needed for licence validation.
Does PopAlert replace our fire alarm?
No. PopAlert complements fire alarms, lockdown alarms and access control by adding the written instruction that sound alone can’t give.
Do we need new screens or hardware?
No. PopAlert works with your existing networked computers. We install a PopAlert control unit on site, and there are no building works or batteries to maintain.
How long does installation take?
PopAlert is installed, configured and tested on site by our team, typically in under a day, with full staff training included.
Does PopAlert help with Martyn’s Law?
Martyn’s Law requires qualifying premises to have procedures for evacuation, invacuation, lockdown and communication. PopAlert is a practical way to deliver the communication part. Read our Martyn’s Law guide.
