in 1961, Mehlich Electronics, Inc. manufactures dependable
voice-communication and electronic signaling systems. Used
in a wide range of applications. The patented multiplex system
greatly reduces the amount of labor and cable required for
conventional communication system.
the early sixties Karl Mehlich (Inventor) and founder of Mehlich
Electronics, Inc. designed a multiplex system, which greatly
reduced the amount of cable, required for a conventional intercom
The Mehlich Multiplex System, it is as the name implies. The
system consists of basically a power supply, and pulse generator
which feeds a trunk cable to which transmitters and receivers
are connected. The trunk line consists of 11control conductors,
1 power supply pair, and 1-shielded pair for voice communications.
Once this trunk cable is installed, master and remote stations,
up to 110 stations can be connected directly to the trunk,
never requiring additional home run cables. This allows for
flexible simple system design and easy future expansion. Much
like a cable T.V. system, the cable can be looped or T-Taped
in any configuration. Each remote device is coded by simply
using two of the conductors in the main trunk (up to 110 devices).
NO HOME RUN CONECPT has been used in all Mehlich Electronics,
Inc. products which over the years has proven to be very reliable.
