This is a fixtures guide of Montgomery elevators in the Unites States.
1910 to 1960s
Many of the Montgomery elevators from the 1910s to the 1930s, along with the Globe and Parallelogram elevators from the early 1940's to the mid 1960's used CJ Anderson fixtures, typically with HNRB buttons that were 3/4" diameter black buttons. Some vintage fixtures had HNRW illuminating white buttons and FG traveling lanterns on the later vintage elevators from the 1950's and 1960's.
1960s to 1980s
Globe & Parallelogram
These are found in the Montgomery Globe & Parallelogram (G&P) elevators from the late 1960s to the mid 1980s, before the modern Montgomery elevators were coming. It has square plastic buttons with white illuminating lamp and black halo. Floor counters are also square plastic lenses with black halo, and bear a close resemblance to the buttons. Directional lanterns usually have triangular lenses that illuminate green for up and red for down, although some newer (1980s) G&P lanterns might have up arrows that illuminate white instead of green, even if the down arrows retained their red illumination.
1980s to 2004
The Montgomery A-Series fixtures are common throughout the middle 1980's (around 1983 to 1986), just when Montgomery switched logo designs from Globe & Parallelogram to the newer "Twinkie M" logo, and were Montgomery's equivalent to fixtures such as the New Otis Lexan, Westinghouse AE, and Dover Classic. The buttons are white with a black halo, clear cap, and are made in either a round button shape (similar to Epco CircleLine), or square button shape (similar to Epco FlushLine). Multi-light floor indicators were also similar in design to the pushbuttons, while digital floor indicators were the digital Montgomery indicator with blue dot-matrix vacuum fluorescent display. Lanterns usually had large round or square lenses with black arrows printed on them, and illuminated white for up, red for down. Because of the flush mounted nature of pushbuttons and floor indicator lenses, A-series fixtures are non-ADA compliant, therefore, making them rare, and subsequently, are also being replaced with newer ADA compliant fixtures.
The Montgomery Vector fixtures were common in the late 1980s and early 1990s, and they were used until most likely not long after Kone bought out Montgomery in 1994. As Montgomery's equivalent to the Otis Series-1 and Dover Impulse, these fixtures uses gray square buttons with a green illumination stripe lamp next to the buttons. Floor indicators are green dot-matrix vacuum fluorescent display, and while the buttons might be ADA compliant, Vector car stations from 1989 and earlier, and some Vector panels from 1990 have the floor buttons mounted too high to meet ADA compliance. As a result, this is why Vector fixtures are rare, and many are now being replaced with newer, ADA compliant fixtures, often from Innovation. The service cabinet is above the buttons, and is not locked.
Series 220 (Montgomery & Montgomery Kone)
The Series 220 fixtures were introduced in 1994 when Kone bought out Montgomery in 1994 as a successor to the Vector fixtures, and they were also a competitor to Dover Impulse, Otis Series 1, and Schindler MT. This fixture line uses black rectangular, Kone M-Series-like buttons with red-LED illuminating halos. On the early Series 220 elevators, the vacuum fluorescent floor counters from the Vector fixtures continued to be used, but later, they were replaced by red-LED fixed character dot matrix floor counters. Around 1999, some elevators with Series 220 fixtures began using Kone's bell chimes (the down chime used two different pitches, creating a "hi-lo" effect), as well an updated Kone-style red LED floor indicator. The Series 220 were offered until 2004, when it was completely replaced with Kone's current KSS fixtures series.
A lot of YouTube elevator enthusiasts mistakenly refer to these fixtures as KSS-220.
Third Party Fixtures
As previously mentioned, Montgomery used CJ Anderson fixtures in its early years right up until the late 1960s when they started manufacturing their own fixtures. However, Montgomery continued to use third party fixtures as well as manufacturing their own; they used Epco fixtures from around the 1970s until the mid 1980s, and then used Innovation during the Twinkie-M and Montgomery Kone eras.
