2001 to present
2000s batch (2001 to 2012)
These were the fixtures used in early Sigma elevators since 2001. They had several variations of button but some of them have been discontinued in the early 2010s.
These buttons were originally produced and used by LG Elevators from the late 1990s until around 2005. In 2001 when the Sigma elevator company was established, these buttons were used by Sigma (as well as most Otis elevators in South Korea) and are still being made as of today. Buttons are rounded rectangular with illuminating halo and number/symbol. Most of them have braille but few buttons may only have illuminating number/symbol as an option. They can also be flushed and surface mounted.
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).
These buttons are square stainless steel with a tiny triangular lamp on the top-left side of the buttons which illuminates in red.
These are round metal polished buttons with braille and amber illumination.
These are white rectangular buttons with a chrome frame and illuminates entirely white.
Most Sigma elevators are using digital segmented indicators with orange illumination, but some elevators also uses LED dot matrix indicators with scrolling arrows. These LED dot matrix indicators can be amber or red, and have been produced since 2005.
In-car station floor indicators (type 1)
This is a rectangular digital floor on the car station above the capacity badge.
In-car station floor indicators (type 2)
This is a vertical rectangular digital or LED floor indicator on the car station.
This is a digital floor counter above the inner door which resembles an old 1980s GoldStar analog or digital floor counter. This series might have been discontinued.
This is a square digital car floor indicator above the landing door. This series has been discontinued.
This is a modular digital floor indicator that is shaped like a speed bump. HID-A122 is a hall floor indicator while CID-10 is a car floor indicator. Both series are an older series prior to 2013.
This is a hall floor indicator which was originally produced during the GoldStar and LG era in the 1990s, and later Sigma continued to produce this type of floor indicator. It is a rectangular display with a slanted display with digital numbers on the center. HID-A132 is mounted on a transom panel, except for HID-C132 where it is mounted on the concrete wall.
These lanterns were originally produced during the GoldStar and LG era in the 1990s, which then Sigma continued producing these lanterns. They are mostly lights up in amber, but in Hong Kong, they would light up in green for up and red for down.
Similar to HLV-C08 but with a translucent triangular arrow on the center.
This is a vertical hall lanterns with slanted lenses.
These are hall lanterns consists of square lens and they lights up orange.
Similar to HLV-C48 but has an LED dot matrix floor indicator under the lanterns.
Current batch (since early 2010s)
In the early 2010s, possibly around 2011 or 2012, Sigma revised their fixtures by eliminating some of their older button variations. Only the rectangular, round metal and white rectangular buttons remains in production for their current elevator models. Most elevators nowadays are using LED dot matrix, but some others also use digital segment displays.
These buttons are now protruded from the panel and have no beep when pressed.
These buttons lights up white when pressed.
Nowadays most Sigma elevators are using LED dot-matrix floor indicators. Their digital floor indicators are rarely used.
In-car station floor indicator
This is a vertical rectangular floor indicator on the car station either with digital segments or LED.
This is a newer CID-10 modular car floor indicator.
This is a long rectangular car floor indicator with LED dot-matrix.
This is a hall floor indicator similar to CIX-13. HIX-A162 is a transom mounted type, except HIX-C162.
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 like cylinder with the buttons positioned on each ends, and somethimes they can have an LCD indicator in between the buttons.
MiniTouch fixtures have black mirror polished hall and car station with touch sensitive or square buttons. Floor indicators are animated LCD displays with floor destinations shown on the screen. This is the only Sigma elevator fixtures that has a brand name.
Fixtures from Otis/Xizi Otis
These are the fixtures used in the American Sigma elevators. They are similar to the Asian version, only the round buttons have a red dot lamp on the center instead of illuminating number (except the hall call and door control buttons which have the regular symbol). Sigma elevators used to be distributed by CemcoLift (a subsidiary of Otis) but since the company has closed down, Sigma elevators are no longer distributed and these fixtures have been discontinued.
Unknown fixtures in Thailand
These fixtures are only found in Thailand. They have stainless steel square buttons with white illuminating halo, and Otis Series 1-style display with Kone KDS-like floor indicators.
In Hong Kong, most Sigma elevators installed under Lift Modernisation Programme are using Dewhurst fixtures with US90-15 push buttons and Vandal Resistant Indicators. Some elevators in private buildings are also using Dewhurst fixtures. Dewhurst chassis are also provided. The Sigma branded Otis elevators (Sigma Muse NV) in Hong Kong also used with those fixtures as well.
In Singapore, most Sigma elevators installed in HDB blocks under Lift Upgrading Programme are using Dewhurst's US90-15 push buttons and LED floor indicator above the door.
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 are using E.M.C.C. series EBS-1 buttons from South Korea. It is unknown if the LED and LCD floor indicators are also made by E.M.C.C.
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, and many elevators have newer chimes which consists of four stages chime for up travel and two stages chime for down travel. Some elevators also have low-pitched version of the original chimes. 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.
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.
