These drawings relate the terminal location to the button C1= Single pole/common bus 84AB1–103 legend orientation. It is possible to rotate the button legends by 90°, changing the Standard Legend Choices orientation. When mounting the keypad, it 3x4 Size: -101, -102 or -103 4x4 Size: -001, -002, -003, -004, -005 or -006 would be rotated 90° to have the legends appear upright. A 3x4 keypad thus becomes a 4x3. Available from your local Grayhill Distributor. For prices and discounts, contact a local Sales Office, an authorized local Distributor or Grayhill. 3. Color. Many colors, other than our standard black housing, are available. Buttons can be made from equivalent plastic in black, red, green, blue and yellow. White legends are used with dark color buttons, black with light ones. Other colors available on special order. 4. Buttons. Legends can be printed on button surface and protected by a snap-on cap in a similar fashion to our insertable legend types. A second option is printing a ‘blank’ button. (One that has the same dimensions as a molded-in legend button with a flat top surface.) Disadvantage is legend wear over time. A third option is molded-in legends, usually requiring tooling. Molded buttons are available with a flat or concave top surface. 5. Legends. Specify the legend requirements for each button. Identify buttons per our dimensional drawings. Caution if keypad has been rotated. Keypads Grayhill, Inc. • 561 Hillgrove Avenue • LaGrange, Illinois 60525-5997 • USA • Phone: 708-354-1040 • Fax: 708-354-2820 • www.grayhill.com 23
