This is a guide of Sabiem elevator fixtures.
1950s to 1960s
Black buttons
Sabied used non-illiminating black buttons and analog floor indicators from the 1950s to the late 1960s. However, some of these buttons were later replaced into illuminating ones in the 1980s by Sabiem or in the 1990s by third-party companies.
Hall Station and Car Floor Indicator
The analog floor indicators usually have green and often yellowish, red or orange illuminated numbers, and are mostly found above the inside doors.
On some smaller and freight elevators with full manual doors, the inside indicators are usually mounted vertically above the button panel. Indicator on hall stations usually have an illuminating "COMING" word which would light up when the call button is pressed.
1970s
Buttons
In the 1970s, Sabiem used round illuminating plastic buttons, but some of these buttons were replaced in the 1990s.
Hall Station and Car Floor Indicator
In the 1970s, Sabiem revised their analog floor indicators, making them black square (resembling mahjong tiles) and lights up in green, but some of them are white and lights up in yellow. These analog indicators are mostly located above the elevator doors. Some of the hall stations often have illuminating "COMING" word which lights up when the call button is pressed, but this has mostly been replaced with an illuminating call button[1]. On some smaller elevators, the outside indicators are usually mounted vertically on the hall stations, similar to those found in Sabiem elevators installed in the 1960s.
1980s
Sabiem continued using their 1970s illuminating buttons and indicators with minor changes until around the mid 1980s. Some of the analog indicators now illuminated in yellow orange and the lenses are now white instead of black.
Later, Sabiem started using rounded square illuminating buttons with black frame and electronic floor indicators. They are used in two elevator types; roped hydraulic and traction (mostly bottom-drive).
Some elevators in old Hong Kong public housing blocks and car park buildings (both were built by either Hong Kong Housing Authority or Hong Kong Housing Society) in the early 1980s are using Dewhurst buttons, mostly the US81 series buttons.
1990s-present
Nowadays, Sabiem installs Kone-based elevators. In this period, and only Hong Kong still takes any new installations as they use Dewhurst US81 braille version buttons in 1990s.
In 2000s or later, some Sabiem elevators in Hong Kong that have been modernized by Shan On Engineering Co. Ltd. (the distributor of Sabiem elevators in Hong Kong) are using fixtures made by Tung Da Electric Co., Ltd.[2][3] Some Kone-based Sabiem elevators in Hong Kong also use Dewhurst US90-15 or US91-15 buttons, or Everbright buttons. However, some of these Everbright buttons have been replaced with Dewhurst buttons due to durability reason.
