This is a list of Dover elevator fixtures.

1960s-1990s

Older GAL

Most standard elevators were using the vintage black round buttons with white letterings during the 1960s. These buttons were made by GAL for Dover. The buttons are very simple without any illumination indication, except the hall stations, which have an in-use light above the button. Additionally, there is no door close button; pressing a floor will close the door quickly and the car starts. Later on, the call buttons had a white halo around them, and an arrow on the button lit up green for up, and red for down, and the floor buttons had a white halo, which lights up when you press the button, but the door open and alarm buttons were not changed.

3rd Party Series

Dover Elevators uses EPCO Haloline. these fixtures was an option of 3rd party orders from 1950s-1987. WS and WA Haloline was common for orders. Some of panels can have Dover branded label or has no branding at all

Few of the Dover Installs used Monitor TR as a fixtures from the 1970s

Traditional

Dover traditional fixtures came out in 1968 and could either be a translucent illuminating button with a black halo or a black button with an illuminating halo. Sometimes, they could be black buttons with black halos, but these were generally used for Door Controls and Alarm Buttons and rarely on freight elevators. The button bases are the exact same as the one's used on Dover Black/White Buttons from the 1960's. The floor counters were translucent wedge shaped illuminating blocks with black numberings - these style of lanterns were also used on elevators made by Dover's British subsidiary Hammond & Champness (H+C) as well as those installed in Canada by Dover distributor Turnbull (these were branded as "Dover/Turnbull").  In the mid 1970s, the black button with the white illuminating halo started becoming less common. Around 1975, the buttons were updated a bit to press differently, in which it barely pushes in and often user don't have to push in too far to activate the button, giving it a flimsy feel. By the late 1970's seven-segment digital floor counters became available and the Older Pushbutton Traditionals were discontinued for the newer white flimsy style buttons introduced in 1975. A black version of this was made in Canada, but is very rare. By the mid-1980's, a door close button became common on Traditional fixtures. By this time, the digital floor counter was a dot-matrix display instead of a seven-segment display. Around 1990, the buttons were altered to stick out more. The 90's version would be continued on by Thyssenkrupp until Late 2007. These fixtures were often called Dover Classic. 

Vandal Resistant (Brushed/Polished Chrome/Brass Traditional)

Not much is known about these fixtures as they are very rare, what is known is that the arrow or number in the middle lights up and the rest of the button is either a metal, or polished chrome, or brass. These buttons resemble and presses like the regular Dover Traditional fixtures since it uses the same base as Traditional buttons since 1975.

Newer Black Halo (Traditional)

These fixtures are extremely rare and were only available with custom order. The buttons have a Black lens with a white halo that lights up when pressed.

Vanity (Fully White Custom Traditional)

Dover "Vanity" Traditional were only available through custom orders. They are almost similar to a OTIS Vanity but it resembles to Dover Traditional Controllers. This is very rare for almost all of the state and only few of the Dover Elevators are installed with these type fixtures.

Traditional Bar Buttons

We don’t know anything about Bar Button Dover Traditional but they appear to be extremely rare as few installations with these. These bar buttons appears to be the Wider White Traditional with no halos on them.

Impulse

Around 1983, Dover introduced Impulse, which was quite common and had a very distinctive look. The floor counter is slanted down 20 degrees toward the floor as are the nameplate, emergency lights, and capacity label. The buttons are square-shaped made of translucent polycarbonate with rounded corners and are slanted upward toward the ceiling. On some elevators, the buttons and floor counter are not slanted; this version of the Impulse is called Custom Impulse and is not as common as the standard Impulse. Until 1994, the door close, door open, and alarm bell had blue braille plates, and the braille plates for door open, door close, and alarm bell were black post 1994.

Button differences

  • The Older buttons used contact blocks and incandescent bulbs and sometimes LED's (the buttons press smoothly and barely press in all the way).
  • The Newer buttons used microswitches and lightbulbs or LED's (the buttons click when pressed and pressed in further).

The indicator often used was an analogue display with symbols that mimic the look of a dot-matrix display. For buildings with more than seven floors, a true Dot Matrix display was used. ThyssenKrupp continued on using Impulse with minor revisions through 2005, but are now no longer made, although spare parts are still available today on special order. Impulse fixtures were also used on Dover elevators outside the US.

Vandal Resistant

Vandal Resistant is a circle metal button with the light in the middle, the light can be either red or yellow, and look very similar to Adams Survivor-Plus buttons. The indicator was either analog or digital.  The analog indicator featured a black circle around the numbers, and a small light (either red or yellow) was below each black circle. The digital indicator was the same one used with Dover Traditional fixtures. These fixtures were continued by ThyssenKrupp until 2007. There is also a California code compliant version, with buttons that look very similar to Schindler vandal resistant fixtures. In addition, the vandal resistant buttons utilized the same assembly as the Impulse buttons, with the dual micro-switch design.

Fake LED floor indicators

Dover made floor indicators that were blocks for each floor number, there would be an incandescent or LED light that would light up that would make the dots light up in the shape of the floor number, on some of the later floor indicators they would use a matrix indicator instead of using different blocks for each number. These floor indicators were used on late Dover traditionals and most Dover Impulses, ThyssenKrupp also continued to use these until 2012.

Floor Passing Sounds/Chimes

Dover has been using mechanical bells for decades for the directional and floor passing sounds on their elevators (some don't have a bell or floor indicator while others have no floor passing sound but with a floor counter). Beginning with the Impulse line, Dover started using electronic bells for the directional indicators (Impulse directional lanterns didn't use mechanical bells). The floor passing sound was either a piezo buzzer, a dog whistle or a higher pitched "chirp"; these floor passing sounds were also used with the Traditional and Vandal-Resistant lines.

The "chirp" was discontinued in the mid-1990s and elevators from then on until 2011 used the piezo buzzer for the floor passing sound.

Trivia

  • From 1969 to 1999, Dover made their elevator fixtures in their Middleton elevator plant in Middleton, TN[1].
