Overview
Otis Spec 50 was Otis's traction elevator model for low to mid rise buildings. It was produced by Nippon Otis in Japan from 1982 until 1989. It was succeeded by the Otis Spec 60VF.
It is basically an improvement of Otis Spec 5, featuring bigger buttons and microcomputer controls. Other than that the design is still pretty much the same like Spec 5.
In Indonesia, this model was mainly installed in low rise commercial buildings and hotels completed in the mid and late 1980s. Only a few installation still remain today, and most of them have already been modernized.
