School lockdown alarm: the biggest challenge during an active shooter or aggression incident is communication
When an active shooter, serious threat or other violent incident occurs at a school, every second counts. Yet the biggest challenge is often not activating the lockdown alarm itself. Triggering an alarm is relatively straightforward. The real challenge begins afterwards.
How do you ensure that hundreds of students, teachers, first aid responders, caretakers, school leaders, security staff and emergency services all receive the right information at the same time? How do you prevent panic, misunderstandings and conflicting instructions? And how do you maintain situational awareness as events unfold?
This is where schools face the greatest challenges in practice.
The biggest challenge during an active shooter or aggression incident
During an active shooter, aggression or other duress incident, different groups need different instructions.
- Teachers and students must immediately receive the correct instructions, whether to lock down, evacuate or shelter in place.
- Emergency responders and security personnel need to know exactly what actions they must take.
- School leaders need a real-time overview of the situation so they can coordinate the response and make informed decisions.
- Emergency services require immediate access to accurate, up-to-date information.
When communication relies on individual phone calls, two-way radios or WhatsApp groups, confusion can quickly arise. Valuable time is lost, while speed and clear communication can save lives.
For this reason, more and more educational institutions are implementing digital emergency notification and crisis management platforms with predefined emergency scenarios. With a single press of a panic button or activation of a lockdown alarm, the right people are alerted instantly and receive role-specific instructions. This enables a faster, more coordinated and more effective response during active shooter, aggression and other emergency situations.
How MultiBel solves this challenge
MultiBel has been developed to help organisations communicate quickly, accurately and in a controlled manner during emergencies.
When an aggression, duress or active shooter scenario is activated, MultiBel automatically alerts the right people through multiple communication channels simultaneously. This means nobody depends on a single system or device.
Alerts can be delivered via:
- The MultiBel app
- Voice calls
- SMS
- Signal lights
- Integration with existing PA and voice alarm systems
Integration with existing PA and voice alarm systems
Many schools already have a public address (PA) system, voice alarm system or emergency voice communication system that enables spoken instructions to be broadcast during an emergency. These systems play an important role by providing immediate audible instructions, for example to initiate a lockdown, instruct occupants to shelter in place or evacuate the building.
However, one major challenge often remains:
How do you ensure that the digital emergency notification system automatically activates the PA system?
If a member of staff first has to trigger an alarm and then manually start a public announcement, valuable time is lost. In addition, PA systems are often only accessible from one or two fixed locations. This increases the risk of delays, inconsistent messaging or communication systems operating independently of one another.
MultiBel integrates with existing PA systems, voice alarm systems and emergency communication infrastructure. As soon as an aggression or active shooter scenario is activated, MultiBel can automatically trigger the appropriate public announcement.
Pre-recorded emergency messages can be played immediately, for example:
- “Remain in your classroom and lock all doors and windows.”
- “Evacuate the building using the nearest emergency exit.”
- “Follow the instructions of the emergency response team.”
At the same time, teachers, emergency responders, security personnel and school leaders receive additional role-specific information on their smartphones, tablets or computers.
The result is a fully integrated emergency communication platform where:
- The PA system informs everyone inside the building.
- MultiBel delivers targeted instructions to specific response groups.
- Crisis coordinators maintain a real-time overview of the incident.
- All communication channels are activated simultaneously.
This allows existing infrastructure to be used to its full potential while significantly improving command and control during an incident.
Different instructions for different roles
One of the greatest risks during a crisis is sending identical information to everyone, even though different people have different responsibilities.
With MultiBel, organisations can define in advance which functional groups receive which information.
For example, a teacher may receive instructions to secure a classroom, while first aid responders are informed about evacuation procedures and school leaders receive a live operational overview of the incident.
Each user only receives information relevant to their role.
Real-time situational awareness
During an emergency, the situation can change within seconds.
Through the MultiBel dashboard and, where applicable, the Critical Event Management (CEM) module, crisis coordinators gain immediate insight into:
- Who has received and acknowledged the alert
- Who is available to respond
- Which actions have already been completed
- Which locations may still be at risk
This enables faster decision-making and more effective coordination throughout the incident.
Know exactly where the incident is taking place
One question immediately arises during almost every aggression or active shooter incident:
Where is it happening?
A message such as “there is an incident in Building B” or “on the third floor” is often insufficient. In large schools, colleges and universities, responders can lose valuable minutes searching for the correct room.
MultiBel’s latest innovation, the AI Positioning System (AI-PS), addresses this challenge.
Using only a smartphone and the existing Wi-Fi infrastructure, AI-PS determines a person’s indoor location with an accuracy of just a few metres. No additional hardware, beacons or complex installations are required.
When someone activates an aggression alarm, panic button or duress alarm, their precise location is automatically included in the alert.
Responders immediately see information such as:
- Building C
- Third floor
- West wing
- Room 3.14
This enables first aid responders, security personnel and emergency services to proceed directly to the correct location instead of searching the building.
Faster response. Reduced impact.
During aggression, violent incidents and active shooter situations, every second matters.
The difference between a response time of 30 seconds and two minutes can have a major impact on the safety of staff, teachers and students.
By combining:
- Instant emergency notification
- Role-based instructions
- Real-time crisis communication
- Accurate indoor positioning
MultiBel provides a complete safety platform that enables organisations to respond faster, coordinate more effectively and minimise the impact of critical incidents.
From knowing that something has happened to knowing where it is happening.
Traditional alarm systems simply indicate that an incident has occurred.
MultiBel with AI-PS shows what is happening, who is involved and exactly where assistance is required.
Schools therefore gain not just an alarm system, but full operational control throughout the incident.
Communication throughout the incident
Raising an alarm is only the beginning.
During an emergency, responders must continue to communicate, coordinate and share information.
MultiBel supports this through:
- Scenario-based group chats
- Automatically initiated conference calls
- Push-to-talk functionality
- Shared operational dashboards
- Automated escalation procedures
This ensures everyone works from the same real-time operational picture.
From everyday aggression to active shooter incidents
Not every situation requires a full lockdown alarm.
Sometimes a discreet notification to a colleague is enough to de-escalate an aggression incident. In other situations, immediate escalation to first aid responders, security personnel, school leadership or emergency services is essential.
MultiBel allows organisations to configure multiple emergency scenarios in advance, ensuring that every incident receives an appropriate and proportionate response.
More than an alarm
A lockdown alarm is far more than a button pressed during an emergency.
It is a complete process involving emergency notification, communication, coordination and incident management. The effectiveness of this process largely determines how quickly an organisation regains control.
Many educational institutions already have PA or voice alarm systems for broadcasting spoken emergency instructions. The real challenge is activating every communication channel simultaneously while ensuring that the right people receive the right information.
MultiBel brings these systems together. Through seamless integration with existing PA, voice alarm and emergency communication systems, spoken announcements can be triggered automatically while teachers, first aid responders, security personnel and school leaders simultaneously receive targeted information via smartphones, voice calls, SMS, email and other communication channels.
Traditional PA systems broadcast messages to buildings.
MultiBel communicates with people.
By combining both technologies, organisations benefit from a single integrated platform for emergency notification, crisis communication and incident coordination.
This helps schools, colleges, universities, healthcare organisations, government bodies and other organisations prepare for everything from everyday aggression incidents to active shooter emergencies. By defining scenarios, assigning roles and automating communication in advance, organisations can respond faster, coordinate more effectively and significantly reduce the impact of critical incidents.
