Article Overview
Practical guidance for real-world site decisions.
A college or university is not a big school. Open campuses, many buildings, adult learners and public access change how a lockdown alarm has to work.
At a Glance
- Campuses have many buildings and open spaces, so coverage has to reach outdoors as well as in.
- Students move between buildings all day and may not know the procedure.
- Zoned alerts let one building lock down without stopping the whole campus.
- Further education colleges are always in Martyn’s Law’s standard tier.
Section 01
Why campuses are harder to lock down
Most schools have one main building and a controlled perimeter. Colleges and universities often have neither. Students move between buildings throughout the day, the public can walk through parts of the site, and libraries, cafés and sports facilities stay open into the evening.
That means a lockdown has to reach people who are outdoors or between buildings, and it has to make sense to students who may never have practised the procedure.
Section 02
Zoning across buildings
On a large campus, locking everything down for an incident in one building can cause more confusion than it prevents. Zoned systems let security or senior staff trigger a lockdown in one building, a group of buildings or the whole site, with the right message for each.
Section 03
Reaching people outside
Outdoor sounders and beacons are essential where students walk between buildings, gather in courtyards or use playing fields. Weatherproof wireless units can be mounted on building exteriors and in open spaces without trenching cables across the site.
Indoors, on-screen alerts such as PopAlert can add a written instruction to every computer and display, which helps in lecture theatres, libraries and IT suites where people may not recognise a tone.
Section 04
Who can trigger a lockdown
Most colleges give trigger access to reception teams, security staff and senior leaders, with portable triggers for staff on patrol. The aim is that anyone who sees a threat can reach a trigger within seconds, while avoiding accidental activations.
Section 05
Martyn’s Law for colleges and universities
Further education colleges are always treated as standard tier under Martyn’s Law, regardless of size. Universities are also covered as education premises, and large university sites may fall within the enhanced tier. Either way, documented lockdown and communication procedures will be expected once the duties apply, expected from spring 2027.
Frequently Asked
Questions we get asked about this
Can one part of a campus lock down without the rest?
Yes. Zoned lockdown systems can alert a single building, a group of buildings or the whole site.
Do lockdown alarms work outdoors?
Yes. Weatherproof sounders and beacons can cover courtyards, car parks and playing fields, which is essential on an open campus.
Does Martyn’s Law apply to colleges?
Further education colleges where 200 or more people can be expected at once are always in the standard tier, which requires procedures for evacuation, invacuation, lockdown and communication.
