The Otis Elevonic 401 was a traction elevator system introduced by Otis in 1981. This model discontinued in 1991 (few years later in Asia) and replaced by Otis Elevonic 411 .

Overview

It was the first elevator control system with synthesized speech as an option, information display, and security systems. It was also one of the first elevator systems equipped with weight sensors to put full cars in express mode, in other words, hall calls are skipped for safety. Elevonic 401 dispatched cars in response to variants in building traffic as they occurred. The Otis Elevonic 401 was later succeeded by the Otis Elevonic 411 and Elevonic 411M in 1990. Not all Otis Elevonic 401 elevators say Elevonic 401 on the panel. These usually have a speed of 1000-1200fpm.

The Elevonic 401 synthesized speech uses a form of computerized speech synthesis and has 111-word vocabulary. It can greet passengers, say whether the elevator is going up or down, announce floors and safety messages.
