General voicing and emergency announcement systems are an ideal evacuation, message and background music broadcast solution used in various places such as schools, hotels, shopping malls, supermarkets, social facilities, factories, offices and similar applications where public safety is important. 

Mertsat makes the project by dividing the system into zones in line with customer demands. It allows different music to be broadcasted in different zones, and in case of emergency, the system broadcasts the pre-recorded voice message by automatically getting to the emergency announcement mode.
