A subscriber calling device "Trombon SORS-AVU" version H, is installed in the public address areas and is designed to make a call to the dispatcher console "Trombon SORS-PD" and organise two-way voice communication with him. To organise communication with immobile groups of population, call devices in the form of a button or a sling can be connected to the subscriber calling device. To inform the personnel that help is needed, an information light and sound board is connected to the subscriber call centre.
