Ready for Martyn's Law.
Under the Terrorism (Protection of Premises) Act 2025, schools where 200 or more people are expected on site need procedures for four things.
teamSOS covers all four, from the first alert to the final report, with a record you can show.

School lockdown alerts, answered.
Short answers to what schools and trusts ask us most. Anything else, we're happy to talk it through.
Ask us a questionWhat is a school lockdown alert system?
It's how staff raise the alarm, and how leaders tell everyone on site to lock down, quickly and without being overheard. With teamSOS, any member of staff can call for help from a phone, tablet or computer, and leaders can send a lockdown Announcement to every screen on site in seconds.
Do we need new hardware, radios or panic buttons?
No. teamSOS runs on the devices your staff already use: iPhone, Android, iPad and tablets, Chromebook, Windows PC, Mac, web browser and interactive whiteboard. Staff can be logged in on as many devices as they like at once.
Will it work if the school network or wifi goes down?
Yes. On phones, teamSOS works over mobile data, so an alert doesn't depend on the school network or wifi.
Can we send a lockdown alert without alarming pupils?
Yes. Announcements can go out silently, and details stay hidden until staff press View, so nothing sensitive appears on a classroom board. When you need to be heard, Windows PCs unmute to play the alert, and iPhones and tablets play it even on silent, with critical alerts on.
How do we know who is safe during a lockdown?
Staff reply to the Announcement with I'M OK or I'M NOT OK in one tap. Your response team sees the picture build live, and anyone NOT OK can say why, so you can reply to them directly.
Does teamSOS help with Martyn's Law?
Yes. Under the Terrorism (Protection of Premises) Act 2025, schools expecting 200 or more people on site need procedures for evacuation, invacuation, lockdown and communication, and schools and FE colleges stay in the standard tier even above 800. teamSOS covers all four procedures, and drills give you evidence you can export. The government has said the duties will start at least 24 months after Royal Assent in April 2025.
Can we practise with lockdown drills?
Yes. Drill Announcements are clearly labelled TEST, and every drill is recorded, so you can export evidence that your procedures work.
Can visitors on site be alerted too?
Yes, if you use InVentry. Lockdown alerts can extend to visitors who are signed in on site.
