F9103 Series WIRELESS EARLY WARNING BROADCAST DEVICE TECHNICAL SPECIFICATION  

GeneralF9103 series wireless early warning broadcast device provides   various wireless early warning broadcast services by public 2G/2.5G/3G/3.5G network and frequency modulation (FM) network.It adopts high-powered industrial 32-bits CPU and embedded real time operating system to realize remote mobile phone and telephone warning, SMS to voice warning, GPRS data to voice warming, FM network warning, local interphone wireless warning, local microphone warning, pre-set messages to voice warning, pre-set MP3 audio warning, audio line in warning.

This device series include F9103S (server station), F9103C (client station) and F9103D (single station). The server station and client station form a complete set to provide early warning broadcast service by frequency modulation (FM) network. That is to say, the server station transfers warning messages to the client station by FM network. Each of these three type devices can achieve the warning function separately.This series device can be widely used in water conservancy, weather, geology disaster prevention projects, and also in school, plaza broadcast use.
