Electronic siren Pavian redesigned to serve as small multifunctional warning centre
The Pavian electronic siren presents the top product line of electronic sirens manufactured by Telegrafia company and the best solution in the field of acoustic warning systems in the world. It is a modular and multi-purpose electronic device designed mainly for the building of complex warning systems that require sophisticated control and siren status monitoring. The siren’s parameters can be fully adaptable in order to satisfy specific customer needs, i.e. it allows customisation in a lot of siren parameters.
Although the standard version of the Pavian siren can still meet the requirements placed on the majority of warning systems, some customers come up with specific, non-standard requirements. In this case, the goal was to create a comprehensive solution for dam warning system control. The Pavian electronic siren was additionally equipped with the 230 V back-up output to supply power to one or more external computers, including monitors, and running Vektra® Warning and Vektra® Monitoring software applications. At the same time, a switch to connect the computers to the external network was integrated.
Obviously, it was necessary for the siren to maintain all its previous functions and capability of operating as the “master”, controlling the entire warning system. It means that besides its ability to broadcast warning messages, it now serves also as a retranslation station by means of which commands are transmitted both ways to the other twelve sirens within the system.
This solution suits every warning system where a small but comprehensive control centre with back-up power supply is required to control several sirens. The system can be supplemented with other modules of the aSCADA® product line, for example, ADIO11 module, providing the system with additional inputs and outputs (binary outputs, current loops, serial COM ports, etc.), to connect external devices. This is one of specific examples to demonstrate that Pavian is not simply an ordinary siren but a complex multi-purpose warning device.
