This is a guide to some fixtures used in Sigma elevator, as well as also applied for Otis in South Korea.

2001 to presentEdit

ButtonsEdit

Rectangular buttonsEdit

A lot of Sigma elevators are using these buttons. These buttons are rounded rectangular metal with red illuminating halo and stripe on top of the button. They are usually have braille, but some do not have braille as an option. These buttons were originally created during the LG elevator era in the late 1990s but they were reused by Sigma in the early 2000s. However, LG still use these buttons until 2005.

Round buttonsEdit

These are round metal buttons with red illuminating lamp on the center. Some elevators in the United States are also using these buttons, and equipped with ADA compliant braille and tactile plates next to them (see American fixtures section).

Square buttonsEdit

These buttons are square stainless steel with a tiny red triangular lamp on the top-left side of the buttons.

Round metal buttonsEdit

These are round metal polished buttons with grooved side, braille, and amber illuminating halo and floor number and symbols.

Floor indicatorsEdit

Digital segments floor inducatorsEdit

Sigma continued to produce GoldStar's 1980s inner floor indicators and 1990s hall floor indicator displays and some LG luxury hall lanterns.[1] There are many styles of these indicators, some of them were actually reused from GoldStar and LG. These indicators are usually lights up in orange, but on some late models, the indicators lights up in red.

LED dot-matrix floor indicatorsEdit

LED dot-matrix floor indicators were introduced in 2005, and are now commonly found in some newer elevators. These indicators have scrolling arrows and their LED color are either red or orange. There are many styles of these indicators.

Hall lanternsEdit

Sigma continues to produce the mid-1990s LG hall lanterns with small revision. These lanterns are round and usually lights up in orange but some lights up in red or green.

MiniTouchEdit

MiniTouch first came out in the early 2010s. Both the hall button and car operating panels are black mirror polished with touch-sensitive buttons, and suggesting that they could be equivalent to Schindler's 3300 fixtures. Some are also using small white square buttons instead of touch-sensitive for the hall call, door control, and alarm buttons. Above the floor buttons is a small LCD screen which displays information and also the position of the elevator. There is also a LCD screen floor indicator above the COP with rotating arrow.

Gen2Edit

There are very few Sigma elevators using New Otis fixtures[2].

American fixturesEdit

In most Sigma elevators in the United States, the buttons are using the round buttons. The floor buttons have a tiny red LED dot lamp on the center as well as black braille and tactile plates next to them. The floor indicators are using the same type as the standard Sigma fixtures, the exterior indicators are the GoldStar-style displays and the inner indicators are the LG-style displays. On both side of the inner door jambs, there are two triangular acryilc lanterns which lights up in green for up and red for down. Floor passing beeps sounds the same as the floor button beeps when pressed (floor button beeps does not applied on the American Sigma elevators).


Unknown fixtures in ThailandEdit

These fixtures are only found in Thailand. They have stainless steel rectangular buttons with red illuminating halo, and either LED dot-matrix or LCD floor indicators.

Generic fixturesEdit

Sigma elevators often use generic Dewhurst fixtures in Singapore and Hong Kong, normally using the US90-15 pushbuttons and vandal-resistant floor indicators (in Hong Kong only). Dewhurst chassis also provided.[3]

ChimesEdit

From the early 2000s, Sigma use two chimes, which sounds once for upward and twice for downward since used in LG Elevator. In the late 2000s, chimes were revised with new sounds, which sounds twice for upward and four times (four stages chime) for downward. Some elevators are still using Sigma's original chimes but they sounds much sharper.

The chimes are also used in the American Sigma elevators, but they chimes on when the doors opening. There are also several styles of lanterns.

TriviaEdit

  • The fixtures used in the United States elevators are similar, but with several arrangements due to the ADA compliant.
  • LG elevators installed from 2001 to 2005 are using Sigma-based fixtures.

NoteEdit

  1. In Hong Kong, the lanterns are green for up and red for down.
  2. [1]
  3. It means only indicators are in corresponding Sigma standard.
