Public Warning Systems
The public warning system offered by Rokura is a reliable, complex, new generation system adapted to the new International concept of public acoustic warning in crisis situations, being designed to provide a high safety and performance level.
This system ensures:
- Notification of the Control/Operational Center on the potential hazardous events.
- Alarming of population from areas exposed to disasters/calamities.
- Addressing live and/or pre recorded voice messages for the coordination and implementation of protection and intervention measures.
- Possibility of easy development and expansion (over 1000 sirens), integration in additional local, county or national level sub-systems.
System components:
- Control and monitoring center - Dispatcher
- Communication networks - cable, radio, GSM, Satellite
- Alarm Equipment - Hörmann electronic sirens
Control Center consists of two major parts:
- Control-PC - controls the system and its human interface
- Main Control Equipment - controls the whole hardware
Assures:
- direct monitoring and control of sirens
- the communication to and from sirens locations
- interfacing with sensors from risk sources
- the transmission of acoustic signals and voice messages
The interface is assured by a software package which provides the operator with:
- graphical representation
- accessibility to all system functions
- automatic testing, detailing and selection functions
- password based access, protected on access levels
Electronic Sirens
Rokura’s Public Warning System uses sirens which operate independently, using dual batteries as energy source.
The availability of warning signals depends on environmental density and basic noises.
With electronic sirens it is possible to define signals in terms of intensity and impulse as well as to define voice messages, depending on the events.
Main features:
- high reliability/long life
- high efficiency
- real time vocal messages
- customized alarm signals
- modular design, their power is a 600W multiple
The type of siren is determined on basis of an acoustic coverage study.
The quality of communications networks is decisive for the overall performance of the entire remote control system. All the elements of the integrated system meet ISO standards for population warning systems.
The system is turn-key delivered and includes design, procurement, installation, civil works, interfacing, commissioning, training and maintenance.

Rokura has implemented downstream of the hydrographical basins managed by Hidroelectrica SA, the only existing system at national level for warning and alarming of the population in case of floods.
- The project started in 2002 and currently allows the management of over 700 operating sirens connected to 18 command and control centers.
- The National Authority of Romanian Waters
Starting with 2008, Rokura has launched the implementation of informational and warning systems downstream of large dams managed by The National Authority of Romanian Waters, such as: Varsolt, Maneciu, Dridu, Rapa Albastra Cal Alb,Negreni, Racova etc. So far over 50 Sirens controlled by 10 command centers were installed.
Local Authorities: City Halls and County Councils
Rokura implemented in 2009, at Dolj County Council, together with its partners, a “Monitoring, Informing and Alarming System in case of natural calamities produced in Danube riverside cities, in Dolj County”, achieving thus the first Monitoring, Alarming and Intervention Center within the Emergency Situations Inspectorate Oltenia.
The system provides modern devices for the management of calamities, being useful in management decisions concerning the intervention in case of disasters, help and support distribution to those affected by natural calamities.
