In the early 1980s, Otis developed the first microprocessor control elevator system,
called the Elevonic
®
101. It was a watershed event and paved the way for future
developments utilizing computer technology.
Advances in microprocessor and data communications technology led to Otis’ first
Remote Elevator Monitoring (REM
®
) system, which was introduced in 1985 and
installed at an Otis elevator site in the United Kingdom.
REM systems monitor elevators 24 hours a day and provide diagnostic information
via a telephone line to our technical center. This information assists our technicians
in preventing elevator disruptions.
1985: Remote Elevator Monitoring (REM
®
) systems monitor elevators 24 hours a day.
