Exterior project – sirens

Take a look at a video related to this project on YouTube

In this demo project, we are going to create a simple local warning system designed for the premises of an industrial company. The goal of the project is to specify the number of electronic sirens necessary for appropriate sound distribution in the area endangered and to define their rough layout. First of all, we have to define the endangered area; by clicking on the toolbox icon called "Add an area of danger"  and by subsequent clicking on the map, the predefined area of a circular shape will open. By pressing the ESC key or the right button of the mouse the process of adding new areas of danger will be cancelled and we can carry on with our work.

In most of the cases, the area of danger is of a circular shape. This time, however, we are going to create an irregularly-shaped polygon of the area of danger that would copy the part of the premises, to which the sound is distributed. With the cursor on the endangered area icon  press the left button of the mouse. You will thus activate the selection, which is indicated by the change in the dart board colour under the icon from black to red  and by the change in the colour of the area border to violet. Tick the option “the area is a circle” in the characteristics box appearing on the right side of the screen and save the changes by clicking on the “Save” icon. Then, click on the “Edit” icon and by repeated clicking on the map limit points of the endangered area are created. The created points can be subsequently moved anywhere on the map. Once the required shape of the area is created, the changes must be saved by clicking on the “Save” icon .

Second of all, we need to add individual electronic sirens. For several reasons, it is generally recommended to use sirens of the 1,200 W output. In special cases, it is also possible to use sirens with a bigger output. As we are going to create an integrated warning system and we need the sirens to be able to connect directly to a sophisticated network of sensors, we decided to go for the highest series of PAVIAN sirens. Click on the PAVIAN 1200 button, which can be found in the left part of the list of products (the number under the name indicates the product Watt output). Then click on the map in order to add new sirens. To cancel the siren adding process, press the ESC key or the right button of the mouse.

We can adjust parameters of each single siren in the right box “characteristics” menu. The parameters we mostly adjust are radiation characteristics (F, 8 or O) influenced by the layout of sound baffles placed on columns and the azimuth i.e. setting of directions, in which the acoustic pressure should be radiated. Any change must be confirmed by its saving, i.e. by clicking on the “Save” icon .

In the same way, we add new sirens, change their position on the map and edit their characteristics until the coverage of the area by acoustic signals meets our requirements. The prepared acoustic project is used as the basis for the preparation of an implementation project.
