This is a list of elevator fixtures used in Sigma elevators, as well as Otis elevators in South Korea.

2001 to early 2010s

First batch (2001 to 2012)

These are the fixtures used in early Sigma elevators from 2001 until the mid 2000s. They had several variations of button but some of them have been discontinued in the early 2010s.

Rectangular buttons

These buttons were originally made by LG Elevators in the late 1990s, and production was carried over to LG-OTIS after Otis bought LG's elevator division in 1999. When Sigma was formed in 2001, the company began using these buttons. These buttons are rounded rectangular with both illuminating halo and number/symbol.

Sigma made two versions of these buttons. The first one is a surface mounted button that comes with braille marks, and the second one is a flush mounted button with our without braille marks. Both versions were commonly used in older Sigma Di (Distributed Inverter) elevators, as well as modernization of older GoldStar elevators. The flush mounted version was also used in older Sigma Iris elevators from the mid 2000s until the early 2010s.

Depending on the type of car station, the type of alarm button used may vary. If the car station has a black capacity plate (where the alarm button, intercom speaker and direction indicators are located), the button is silver round. If the car station does not have the plate, the button is the same as the other buttons but it is yellow instead.

Round buttons

These are round domed buttons with red illuminating lamp in the middle. The alarm button is round silver, and it is found on the capacity plate. They were also used in the American Sigma elevators in the United States and Puerto Rico, which have been modified to include braille plates next to the buttons to meet ADA compliance.

Square buttons

These are square domed buttons with a rectangular halo. The alarm button is square silver, and it is found on the capacity plate. They have a tiny red lamp on the top left corner of the button, as well as red illuminating number/symbol in the middle.

Floor indicators

Sigma used 16-segments display which light up either red or orange for the floor indicators. The floor indicator on the car station is a rectangular display above the capacity plate. The two directional arrows, which are orange illuminating triangles, can be on the floor indicator itself or on a black capacity plate below the indicator (along with the alarm button). By 2005, indicators LED dot matrix indicators with a scrolling arrow became available.

Second batch (mid 2000s to 2012)

This batch of fixtures was launched in the mid 2000s and has a slightly different design. It was used in the newer batch of Sigma Di elevators, as well as Sigma Solon and MUSE MRL elevators produced from the mid 2000s until at least 2012. Some modernization of older GoldStar elevators under this brand also used these fixtures. These fixtures use a yellow round or rectangle alarm button found on the capacity plate.

Round silver buttons

These are round silver buttons with braille marks and orange illuminating halo and number/symbol.

Rectangular buttons

These buttons are the same as the ones used in early Sigma elevators, except that they are surface mounted.

White buttons

These are white rectangular buttons with a chrome frame and black marking in the middle. They illuminate white when pressed.

Floor indicators

Sigma redesigned the floor indicator display on the car station by making them rectangular and vertical, with a tall white capacity plate attached under the indicator. These indicators can use either 16-segments or LED dot matrix display with a scrolling arrow.

Sigma also made another type of floor indicator display on the car station which is rectangular, and does not attached with the capacity plate.

Overhead floor indicators

Sigma made many styles of overhead floor indicators, which are installed above the hall and/or car doors. Most of these indicators use 16-segments display, but there are a few which use LED dot matrix display with a scrolling arrow. A few of these are actually remake of the original 1980s-1990s GoldStar/LG indicators.

American fixtures

The fixtures used in the American Sigma elevators (which are found in the United States and Puerto Rico) are similar to the ones used in Asia. They used the round domed shape buttons, with the illuminating number in the middle replaced with a dot lamp. In addition, braille plates are placed next to the buttons to meet ADA compliance. For the landing floor indicator, it used the HID-C132 series which is mounted on the wall. There are also car lanterns installed on the door jambs inside the elevator. These fixtures were discontinued when Sigma's American distributor, CemcoLift (which was a subsidiary of Otis), went out of business in 2011.

2012 to current

When Sigma launched their new Iris NV (ACRA since 2019), Solon NV (Solon Comfort since 2019), Muse NV and Iris 3 elevators in 2012, Sigma updated their fixtures with a few revisions. Several button, indicator and hall lantern variants were removed from the lineup, new chimes were introduced, and most of the floor indicators began to adopt LED dot matrix display. Possibly in 2015, the 16-segments display, which have been used by Sigma for more than 10 years, was completely dropped from the lineup and replaced with LED dot matrix display. The rectangular buttons and button beep were also dropped sometime in the mid 2010s.

Rectangular buttons

Sigma continued on making these buttons until around the mid 2010s when they were officially discontinued.

Round metallic buttons

These are the same as the ones used from the mid 2000s until the early 2010s.

Fixtures used in ACRA, Solon NV and Muse NV elevators

These fixtures consists of Otis/Xizi Otis's BR27A(B) concave buttons with blue or red illuminating halo and LCD indicators with segmented numbers. The call stations are shaped cylindrical with the buttons positioned on each ends, and sometimes they can have an LCD indicator in between the buttons. These fixtures are only used in Sigma Solon NV and Muse NV MRL elevators. They are based on the fixtures used in the Otis Gen2 Dynamic elevators in South Korea.


MiniTouch is a fixtures lineup made of tempered glass, featuring touch sensitive call stations, touch screen car stations and LCD floor indicators. This is the only Sigma elevator fixtures that has an official name.

Fixtures from Otis/Xizi Otis

There are very few Sigma elevators using fixtures from Otis/Xizi Otis. It is unknown if these fixtures are still offered for the current batch elevators.[1].

Suzhou Express fixtures

Some Sigma elevators in Thailand and Indonesia use these fixtures, which are from Suzhou Express in China. They have stainless steel square buttons with white illuminating halo, and Otis Series 1-style floor indicator display with Kone KDS-like LED dot matrix display.

Fixtures used in Sigma DDS system


Destination indicators

Third-party/generic fixtures


In Hong Kong, most Sigma elevators installed in the Public Housing Estate blocks built by Hong Kong Housing Authority use Dewhurst fixtures with US90-15 push buttons and Vandal Resistant Indicators [2]. Some elevators in private buildings are also using Dewhurst fixtures. Dewhurst chassis are also provided[3]. The Sigma branded Otis elevators (Sigma Muse and Muse NV) in Hong Kong also used with those fixtures as well[4][5][6][7].

In Singapore, most Sigma elevators installed in HDB blocks under Lift Upgrading Programme use Dewhurst's US90-15 push buttons and LED floor indicator above the door.

Shanghai STEP

Some Sigma elevators in Thailand and Singapore, particularly newer home elevators installed in Housing and Development Board (HDB) blocks under Lift Upgrading Programme are using Shanghai STEP fixtures. These fixtures mostly consists of EB111 push buttons and orange LED square dot-matrix indicators.


Some Sigma elevators in Thailand use E.M.C.C.'s EBS-1 series buttons from South Korea[8]. It is unknown if the LED and LCD floor indicators are also made by E.M.C.C.


Some Sigma elevators in Hong Kong use Vander LED dot matrix floor indicator.

Chimes and beeps

From the early 2000s, Sigma use two chimes, which sounds once for upward and twice for downward. These chimes were originally introduced by LG Elevators in the very late 1990s. By mid 2000s, the chimes were modified to sound sharper than the original chimes[9], and many elevators have newer chimes which consists of four stages chime for up travel and two stages chime for down travel[10]. Some elevators also have low-pitched version of the original chimes.[11] Sometime in the early 2010s, new version of both four and two stages chimes were introduced, which sounds very similar to SJEC elevators in China.[12][13]

Since 2001, almost every Sigma elevators have beeping floor buttons when pressed. Nowadays this beep is rarely heard in newer Sigma elevators. However, Sigma elevators installed in the United States do not have floor button beep. Instead the beep is used as floor passing chime.
