The Elevonic® 411M control system, designed for mid- and high-rise elevator upgrades, replaces the traditional analog selector with a digitally-controlled, primary velocity transducer. The result: A vastly superior experience in every possible degree.
The 411M modernization system includes:
  • The Relative System Response Plus (RSR Plus) dispatcher, the most efficient in the industry, consistently delivers the shortest waiting times with the minimum number of elevators
  • Early Car Announcement (ECA) with Fuzzy Logic dispatching informs passengers which car will answer their call one second after the hall button has been pushed
  • Using 154 infrared emitters and detectors to create an invisible safety net across the elevator entrance, the OPTIGUARD™ system offers maximum protection for passenger safety
  • Digital closed-loop position and velocity feedback systems produce a smoother, quicker ride with consistent, precise leveling
The 411M modernization extends to:
  • Maintenance: The Otis Maintenance Management System (OMMS) is the industry's most advanced and effective building service system. OTISLINE®, Otis' communications center, provides dispatching service 24 hours a day, seven days a week
  • Monitoring: Remote Elevator Monitoring — REM® — combines microprocessor technology with advanced data communications to provide comprehensive, around-the-clock diagnostic and detection service
  • Installation: Years of experience enable Otis to offer a highly efficient process that ensures that your project is completed on time and within budget
  • A smaller, safer system, with fewer moving parts, requiring less maintenance
  • Greater efficiency, more consistent operation and dramatically reduced operating costs
  • Top-to-bottom modernization programs, featuring a full range of state-of-the-art components, services and systems
  • An installation process as efficient as the finished product
