Our wireless floor call system for building hoist is a new generation with high confidentiality, large storage space, stable


performance and low power consumption. Meanwhile it doesn't need to use traditional skipped stitches or DIP switch coding, and
 
just make host to learn wireless signals that lauched by wireless son host. If the son host is lost or broken, you can make another
 
similar son host to learn with the host. It's very convenient.
