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

performance and low power consumption. Meanwhile it doesn''t need to usetraditional skipped stitches or DIP switch coding, and

  wireless alarm system

make host tolearnwireless signals that lauched by wireless son host. If the son hostis lost or broken, you can make another

similar son host to learn with the host. It''s very convenient.
