Emergency Voice Evacuation Alarm System how does it work

Voice evacuation alarm system, based on local area network (LAN) hardware technology and network protocol, is a set of fire alarm & public address system. Transmit digital audio via LAN, not only ensure that the audio signal can achieve long-distance transmission, but also solve signal attenuation, environmental electric/magnetic harassment and other issues in long-distance transmission; Adopt network architecture transmission, significantly reducing the cost of system construction and pre-wiring, which can bring convenience to system expansion and system maintenance at later stages. Voice evacuation alarm system can meet the various needs of fire broadcast, announcement broadcast, background music broadcast and etc. It's controlled by modular MPU with high investment efficiency, while supporting linkage with fire alarm controller of multi-wire-mode or bus-mode, and interface problems between different systems cease to exist. With Self-developed ASD system automatic fault diagnosis technology, SIM speaker lines automatic detection technology and DLB data lines automatic redundancy technology, system works more safely, stable and reliable, and significantly shorten the pre-purchase period and reduce future maintenance costs. Voice evacuation alarm system adopts modular design and modern technology. Long-term industry experience accumulation and comprehensive system tests ensure its stability. System can play background music in the absence of fire disaster, and once the fire is detected system will immediately enter a pre-set alarm state. System is powerful, user-friendly and easy to operate. System is not only widely used in stadium (gymnasium), financial centers, hotels, office buildings, commercial centers, railway stations, airports, exhibition halls and etc., but also suitable for industrial areas such as petrochemical, electric power, metallurgy, iron and steel base and etc. learn more: http://www.itc-pa.com.cn/Product/sort...   / gzitc     / guangzhouitc
