All the benefits of Stiller Alarm’s desktop alarm software
Immediately after the silent alarm is triggered, colleagues are alerted via a notification on their screens and can provide assistance. In addition to all essential information such as name, room, and time, the alarm can also be acknowledged or confirmed. The very possibility of triggering an alarm significantly enhances employees’ sense of safety in the workplace.
The software is designed so that employees can easily trigger an alarm even in stressful situations (e.g., USB button, simple keyboard shortcut, or click on a desktop icon). The alarm is triggered directly from the workflow, meaning there is no need to use the phone system. This ensures the call for help is clear while keeping the alert simple and discreet.
Inform your employees selectively about evacuation alerts. With flexible group management and custom text input, you can control which employees should use which escape routes.
Alerts can still be triggered even if the screen is locked or the server goes down!
Work easily and effortlessly from any location — via laptop, the app, or the Telekom mobile alarm transmitter — with full protection.
When an alarm is triggered, the correct procedures are automatically initiated: response teams immediately receive all relevant information, communication channels are set up, and specific action recommendations are sent depending on the type of threat.
Stiller Alarm meets the DIN VDE V 0827 standard and provides comprehensive protection for every end user in accordance with ISO 9241.
The software is designed for use with 15 or more employees and has been successfully deployed across various industries for over 18 years. The number of users can be scaled without limit.
The number of users and available features can be easily expanded at any time. For example, you can also add the “Mobile Working” feature for laptops or integrate the Stiller Alarm Mobile App.
Specifically designed for large organizations with many workstations, Stiller Alarm offers one-click alarm simulation to test your implemented alarm plan. This allows you to immediately see which workstations will be alerted in an emergency and which will not, providing optimal support for planning and ensuring the reliable deployment of the alerting software.
The platform-independent Stiller Alarm software is simple to set up and install. Installation and configuration take only a few minutes. You are guided by a straightforward installation manual and, if needed, personally supported by our team. We can also handle the deployment for you, whether remotely or on-site.
Purchasing and operating the software (on-premises) is very cost-effective. Depending on the number of licenses and additional features required, you pay a one-time license fee plus a proportional subscription (for updates and access to support). Subscriptions are mandatory for the first year and optional thereafter.
You can test the Stiller Alarm software for 90 days free of charge, with all features included.
Changes can be made quickly, intuitively, and easily in the web-based administration portal. For example, end devices can be configured using drag & drop.
The administrator has a clear overview of all triggered alarms (device, time, and alarm type) through the logging function.
The alarm can also be sent via SMS or email, for example to notify security personnel who do not have access to a PC workstation.
Stiller Alarm meets the standards for emergency and hazard systems: DIN VDE V 0827-1 and DIN VDE V 0827-2.
From security planning and de-escalation training to health checks and integration with the control center — your maximum protection is our goal.

Intuitive administration
The Stiller Alarm alerting solution is easily managed through a central, web-based administration interface — the Stiller Alarm Portal. As an administrator, you can configure all important settings and make changes in one place. The portal manages both the desktop alerting software and the mobile app, giving administrators a clear overview and allowing them to assign all users within the company efficiently.
Key functions include:
- Definition & adjustments of multiple levels (company, location, floor, alarm group, room) and devices — all via drag & drop
- Alarm simulation — test your alarm plan at the push of a button
- Floor plans — for visual support
- Logging function — overview of all alarms sent within the company
- Feature management — activate additional functions, e.g., low-user alarms, alarm acknowledgment, or alarm cancellation
- Extensions — add users and functionalities (e.g., fire alarm systems)
You can also explore our tutorial videos for the Stiller Alarm Portal, which demonstrate how intuitively the portal allows you to set up and manage your entire alerting system.
Optional extensions
Alarm button (button or switches via USB) often give employees an added sense of security when using the system.
Mobile alarm transmitters are provided by Deutsche Telekom GmbH and use the mobile network to send alerts. This ensures full protection even without a PC or client device.
Automated crisis management allows the appropriate procedures to be triggered automatically via the alert system: response teams immediately receive all relevant information, communication channels are set up, and — depending on the type of threat — specific action recommendations are delivered.
