A clear COP or LOP inquiry starts with the project context and the information already available. You do not need to have every detail before making contact, but the following references can make product review more efficient.
Information to prepare
1. Existing Panel Dimensions
Share the overall panel size, opening dimensions and any available installation drawing. For a replacement project, include measurements of the existing opening rather than relying only on the visible front panel.
2. Floor Quantity and Button Layout
Confirm the number of floors and the preferred arrangement of floor and function buttons. A marked-up sketch or reference photo can help communicate the intended layout.
3. Display Requirements
Describe the information the display needs to present, such as floor indication or direction. Include a reference image or existing display information when available.
4. Working Voltage
Provide the required working voltage from the project documentation or existing product identification. If it is not known, share the available wiring or controller references for review.
5. Signal / Communication Interface
Identify the required signal or communication interface where this information is available. Connector photos, wiring diagrams and controller references are useful for replacement requirements.
6. Installation Method
Confirm how the panel will be installed and provide details of the mounting surface or opening. Installation photos can clarify conditions that are difficult to describe with dimensions alone.
7. Material and Surface Finish
State the preferred panel material, color and surface finish, or provide a physical or photographic reference that shows the required appearance.
8. Required Quantity
Indicate the expected quantity and whether the requirement is for one project, a sample review or repeat supply. This helps frame the inquiry correctly.
9. Existing Photos, Drawings or Samples
Front, rear and side photos can reveal useful installation and connection details. Include drawings, labels or an existing sample when they are available.
10. Replacement Project vs New Installation
Clarify whether the panel must match an existing installation or will be used in a new project. Replacement work usually requires closer attention to existing dimensions, interfaces and appearance.
