What is a Silent Alarm?
A silent alarm (also known as silent alert, personal emergency signal or panic button) is an emergency system that silently requests help in dangerous situations – without perpetrators or bystanders noticing.
Unlike acoustic alarms, the silent alarm makes no noise at the trigger point. Instead, predefined recipients – security service, supervisors or external control centers – are immediately informed while the on-site situation remains calm.
With IDERI note, the silent alarm is fully software-based and integrates into any existing Windows infrastructure – without expensive special cabling or third-party systems.

Is a silent alarm mandatory for businesses?
Under § 5 ArbSchG (German Occupational Health & Safety Act), all employers are required to conduct a risk assessment. For workplaces with customer contact, lone working or elevated violence risk, DGUV and professional trade associations explicitly recommend silent alerting measures. In industries such as banking, social services and public authorities, a silent alarm may be part of the legally required occupational safety standard. Non-compliance can result in fines of up to €25,000.
