Why this matters
First state whether the enquiry requires an exact approved model or a product selected against functional requirements. Mixing these two approaches leads to quotations that cannot be compared.
What to confirm
Link quantities to door points or equipment locations. Photographs should be accompanied by written dimensions, and the enquiry should state environmental, keying, power, interface and documentation requirements.
A practical working method
Issue technical clarifications in a controlled revision and require bidders to identify assumptions, exclusions and alternatives. Compare offers against the same scope rather than headline price alone.
Records, acceptance and handover
Before ordering, work backwards from the quotation to the door schedule and project requirements. Confirm model, accessories, quantity, delivery location, documents and acceptance basis one final time.
Evidence and scope
This article is intended for preliminary product and project discussions. Product functions, performance, certification, compatibility and availability must be checked against current documentation for the selected model and the actual project requirements. Application examples are not claims of completed customer projects.
