Advantages of a silent alarm
What is a silent alarm?
A “silent alarm” is a type of alarm that is triggered inconspicuously and discreetly—without sirens, flashing lights, or attracting attention from outside. While traditional alarm systems rely on volume and visibility, the silent alarm aims to inform helpers immediately and securely without alerting the potential perpetrator or bystanders.
Especially in sensitive situations such as robberies, threats, or medical emergencies, this inconspicuous alarm can make all the difference. Employees remain capable of acting, and support is initiated without provoking an escalation.
Can a silent alarm help you?
A silent alarm is much more than an additional security feature—it is a crucial component of emergency management. It helps in critical situations by:
- Call for help quickly.
- Avoid escalations.
- Protect employees and visitors.
- Follow clear internal procedures.
With IDERI note, this silent alarm is implemented digitally and directly. Messages appear immediately on employees' screens—as tickers, pop-ups, or full-screen displays. This ensures that information is noticed immediately and without delay.
In which areas is a silent alarm indispensable?
A silent alarm should be used wherever safety, protection, and quick responses are essential. Typical areas of application are:
- Schools and educational institutions – in the event of threat scenarios or rampages.
- Banks and retail stores – in the event of robberies or thefts.
- Public administration – protection of employees in the event of aggressive encounters with citizens.
- Industry and production – in dangerous situations such as fires, gas leaks, or technical malfunctions.
Wherever large numbers of people gather or critical infrastructure needs to be protected, a silent alarm is now a minimum requirement.
Application example: Public institutions
Imagine that an employee is being threatened. Instead of triggering a loud alarm that could exacerbate the situation, they press a key combination or a hand or foot switch. Immediately, a discreet alarm message appears on all relevant screens in the building: “Emergency at reception – please help!”
Security responds immediately, the perpetrator is unaware of the alarm, and the situation can be quickly defused.
Similar scenarios can also be implemented in schools or retail stores – the inconspicuous yet secure alarm system makes all the difference.
