These nodes are connected to the switches that are set on every floor though RJ-45. All the switches get ac

9、cess to the network of Ethernet. At the same time, a host computer and server will link to the Internet; the data of fire detection will easily be acquired anywhere.There are several advantages in this design: the system can carry enough nodes for the building as many as needed; nodes are very easy

10、to be added in or removed from the network; routing maintenanc e become very easy; the data transmission is reliable and convenient to be acquired; since each node has astatic IP address, the fire is mucheasier to be located.2. NETWORK NODE OF COMPLEX FIRE DETECTIONFire detectors are deployed in the
