Warning for the site and its surroundings
One system for warning on site and around it, from design to service.
Legal duty in the Czech Republic: category B establishments
The operator of an establishment classified in category B, after consultation with the regional fire rescue service, acquires, maintains and operates warning end devices in the emergency planning zone.
Section 26(3) of Czech Act No. 224/2015 Coll., on the prevention of major accidents (unofficial translation)
We design warning end devices for your emergency planning zone, prepare complete project documentation, and supply, install and service the system. Connection to the Czech JSVV is approved by the regional fire rescue service if the devices meet the technical requirements of the Directorate General of the Fire Rescue Service (Section 9(7) of Decree No. 380/2002 Coll.).

Who must have warning end devices?
In the Czech Republic, Section 26(3) of Act No. 224/2015 Coll., on the prevention of major accidents, requires the operator of an establishment classified in category B to acquire, maintain and operate warning end devices in the emergency planning zone, after consultation with the regional fire rescue service.
Can the devices be connected to the Czech JSVV?
Crisis One components can be integrated into the Czech Unified Warning and Notification System (JSVV) as required by the Fire Rescue Service of the Czech Republic. Connection of an end device to the JSVV is approved by the regional fire rescue service if the device meets the technical requirements set by the Directorate General of the Fire Rescue Service (Section 9(7) of Decree No. 380/2002 Coll.).
Will the system work during a power outage?
Yes. All components have integrated backup power for at least 72 hours, and the units can operate independently even if they lose connection with the broadcasting station.
Do we need to run cables across the site?
No. The components communicate over a digital two-way radio network with high resistance to interference, so the installation requires no excavation or new cabling.
Can the system also be used for everyday announcements to employees?
Yes. The system is used both for warning and for information. The speakers play pre-recorded announcements and live broadcasts with high intelligibility.
How can the system be financed?
As the manufacturer, we offer our own flexible installment financing. We also map Czech and European grant programmes and select a suitable option for your project.
