A specification must let you verify delivery line by line and reproduce the agreed result.
For: Procurement and project managers
Display and exact variants
Record manufacturer, series, variant, pitch, actual dimensions and module or cabinet quantities. Clarify front or rear service, environmental requirements and spares. Area alone does not make two offers comparable.
Complete signal and power paths
List the video source, processing, sending device, receiving cards, connections and software. Check capabilities alongside load and operating mode. Describe power separately: supplies, distribution, lines and site requirements. Matching connectors or dimensions does not prove assembly compatibility.
Supply boundaries and deliverables
Itemize structure, design, installation, configuration, checks, training, documentation, packaging and delivery. Define each work item's deliverable and responsibilities. Agree the scope in the quote: turnkey wording does not replace a list of what the customer receives.
Supply scope template
For each line record model, revision where relevant, quantity, unit and confirmation status. Agree substitutions in writing: a similar series may not preserve interfaces or operating modes.
| Group | Contents | Deliverable |
|---|---|---|
| Display | Cabinets, modules, cards, spares | Exact variant schedule |
| Signal path | Source, processor, links | Port map and layout |
| Power and structure | Supplies, distribution, fixings | Design documents and work boundaries |
| Commissioning | Setup, testing, training | Test record and configuration backup |
Record versions and exclusions
Assign a document number and date. State who prepares the wall, provides power and networking, lifting equipment, access and content. Before payment compare the final quote with this revision. At acceptance check serial numbers and quantities and record unapproved changes as discrepancies.
Practice: a kit without a complete system
An offer lists cabinets and a controller but omits the video source, interconnects and configuration. The buyer assumes these are included; the supplier assigns them to the customer. Trace the whole path from a file to the displayed image and assign a supplier for every element.
Separately record consumables, fixings, cable lengths, spares and commissioning deliverables. A length only known after surveying remains provisional with a clear process for confirmation.
- Module and cabinet quantities are distinct line items.
- Spares are separate from installed equipment.
- A service needs a measurable handover deliverable.
Before your next step
- Exact models and quantities are listed
- Equipment, work and shipping are separated
- Exclusions and customer responsibilities are explicit
- Drawings, settings and instructions are handed over
- Specification revision is linked to the quotation
Sources and applicability
This is an editorial guide, not validation of a particular product configuration. Teaching examples are not TOUCHLED product specifications or prices.
These sources explain technical principles and the models they describe. Check current documentation for the exact variant and firmware: a cited revision is not necessarily the latest or applicable to all equipment.
