Lockdown Alarm Misconceptions: The Threat Isn't Always an Intruder
When schools talk about lockdown, we still hear the term “intruder alarm” surprisingly often. But that description can encourage schools to prepare for only one type of threat.
A lockdown alarm is not simply an intruder alarm
An intruder alarm is normally associated with somebody entering a building or site without permission. A school lockdown alert serves a different purpose: it helps a school communicate rapidly when people need to respond to an immediate threat.
The person creating that threat may not have climbed a fence or broken through a door. They may already be on the premises legitimately.
It could involve a pupil. It could involve a parent. It could involve a visitor or contractor. It could also be an incident developing outside the school that makes normal movement unsafe.
The important question is not simply “Can somebody get into our school?” It is: “What would we do if somebody who is already here became a serious threat?”
“We don't get trouble here”
This is another comment we hear regularly. A school may be in a relatively low-crime area. It may be a private school. It may have strong gates and good perimeter security. Staff may rarely see strangers on the site.
Hopefully that remains the case.
But “it hasn't happened here” is not the same as “it couldn't happen here.”
Emergency planning is not about suggesting that serious incidents are common. It is about having a proportionate, practised response to something that may be rare but potentially serious.
Good security does not remove the need for preparedness
Some schools can enclose almost their entire site. Others cannot because of public footpaths, shared buildings, open playing fields or the layout of the premises. In either case, physical security and emergency communication are different parts of the school's overall response.
Try this with five random members of staff
Don't ask only the headteacher, safeguarding lead or the person who wrote the lockdown policy. Pick five members of staff at random and ask them the following questions.
What is the biggest realistic security threat facing this school?
Do all five members of staff broadly identify the same risks, or do you receive five completely different answers?
A pupil says somebody is attacking people with a knife. What do you do first?
Do you investigate? Do you run towards the incident? Do you contact reception? Can you raise an emergency alert yourself? Most importantly, how long would it take before the rest of the school knew?
A serious bomb threat is received right now. What happens next?
A bomb threat does not automatically mean lockdown. Depending on the circumstances, the correct response may involve evacuation, invacuation, lockdown or another emergency procedure. Does the member of staff know who to contact and how everyone would be informed?
What does your lockdown alert sound or look like?
Could staff recognise it immediately? Is it clearly distinguishable from your fire alarm, and do they know what action they are expected to take?
Would you receive the alert everywhere?
What happens in playgrounds, toilets, sports halls, detached buildings, offices or other areas where somebody may not hear a conventional sounder?
If five members of staff give five different answers, the problem may not be your written policy. The problem may be how quickly and consistently that policy can be put into action.
“The headteacher will decide what to do”
A school's emergency plan should establish authority and responsibilities. But it should also consider what happens in the first few seconds of a developing incident.
Imagine that a teacher witnesses an immediate serious threat. Does the information need to travel: teacher → reception → senior leader → headteacher → reception → alarm?
What happens if reception is busy? What if the headteacher is off site? What if the dangerous person is between the member of staff and the office?
Technology cannot decide whether a school should lockdown. But once the appropriate response has been determined, technology can help communicate it rapidly and consistently.
“We'll just phone classrooms, shout or send an email”
That may form part of a school's plan, but it should be tested rather than assumed.
- How long would it take to contact every classroom?
- What happens if somebody does not answer?
- How are staff outside the main building warned?
- Would the message reach noisy classrooms, toilets and corridors?
- What happens if Wi-Fi, a computer or a phone is not immediately available?
- How does everybody know that the message is genuine and requires immediate action?
A dedicated lockdown alert can provide a recognisable signal across the site, helping reduce the need for staff to interpret several separate messages during a rapidly developing incident.
“We have a lockdown policy, so we're covered”
A written policy is important. But a document stored in a folder does not communicate an emergency.
The practical questions are whether:
- staff know the procedure;
- the correct people can initiate the response quickly;
- the alert reaches everyone who needs it;
- staff recognise what the alert means;
- the system and procedure are tested;
- people know what to do after the alert is raised.
A good lockdown alarm should support the school's emergency procedure. It does not replace risk assessment, training, safeguarding responsibilities or leadership decisions.
“This is only about terrorism”
Terrorism is an important part of current protective-security planning, but school lockdown planning is broader than terrorism.
Schools need to consider a range of realistic internal and external risks. Depending on the circumstances, the safest response may be evacuation, invacuation, lockdown or another controlled procedure.
That is another reason why the phrase “intruder alarm” can be misleading. The threat does not have to be a stranger and it does not necessarily start outside the school gates.
What if the threat is a parent?
Parents normally have a legitimate reason to be on or near a school site. That does not mean every interaction will remain safe.
During one school visit, a headteacher told us that she had genuinely been frightened by the behaviour of a parent, and that the caretaker had needed to intervene on several occasions.
That parent was not an “intruder”. The issue was that somebody who had a legitimate reason to attend the school had become a potential threat.
The same principle applies to pupils. A young person may be experiencing severe stress, mental-health difficulties, problems at home or another crisis. Schools should not assume that every serious threat will come from an unknown adult entering from outside.
“We never have trouble here” is reassuring history. It is not an emergency procedure.
Preparedness is not about frightening people
Schools should not operate as fortresses and staff should not spend every day expecting a serious incident.
The objective is proportionate preparedness: if an unusual but serious situation develops, staff should not be inventing the procedure while it is happening.
A well-designed system should be simple to understand, easy to test and appropriate to the individual school.
One final question
Ask this at your next staff meeting:
“If a serious threat developed somewhere in this school right now, how would you alert everybody else?”
If everybody gives a confident and consistent answer, that is reassuring.
If the answers are “I'd probably phone reception”, “I think the head activates it”, “Isn't it the fire alarm?” or “I'm not actually sure”, you may have identified something worth reviewing.
Would you like Camelott to review your lockdown arrangements?
Camelott can review your existing lockdown alarm, site coverage and communication arrangements, discuss what is already working and identify areas that may warrant further consideration. You do not need to have decided to replace your existing system.
Every school's circumstances are different. Decisions about evacuation, invacuation, lockdown and emergency procedures should be based on the school's own risk assessment and appropriate official guidance. An alarm system supports an emergency procedure; it does not replace appropriate risk assessment, staff training, safeguarding responsibilities or advice from the appropriate authorities.
