OEM ACCEPTANCE GUIDE
An OEM acceptance test confirms that the branded, configured and integrated controller matches the agreed release—not just the supplier’s base model.

Test the released OEM configuration
An OEM integration acceptance test must identify the exact controller hardware, firmware, protocol and configuration under test. Generic factory test results are useful background, but they do not prove that the branded and customized release behaves as the integrator expects.
Define the acceptance record
| Test group | Representative checks | Evidence |
|---|---|---|
| Identity | Model, serial number, boards, firmware and protocol version | Photographs and version report |
| I/O | Every configured output, detector and auxiliary input | Channel-by-channel result |
| Control | Plans, transitions, clearance, flash and local fallback | Timed scenario log |
| Integration | Commands, status, alarms, timestamps and permissions | Packet trace and central-system record |
| Recovery | Power cycle, network loss, restart and invalid request | Observed state and alarm behavior |
| Documentation | Manuals, wiring, protocol, release notes and labels | Controlled document list |
Use requirements as test inputs
Every acceptance case should reference a requirement or tender clause and define preconditions, steps, expected result and retained evidence. Avoid “works normally” as an acceptance result. Record measured timing, status codes, alarm text and configuration values.
Include negative and boundary cases
Test invalid commands, maximum configured I/O, timing limits, incomplete messages, interrupted communications and restart during normal operation. Negative tests demonstrate that the controller rejects unsupported or unsafe requests predictably and leaves a diagnosable event record.
Control exceptions
If a case fails, assign an owner, severity, temporary restriction and retest requirement. Do not hide a known exception inside meeting notes. The final acceptance sheet should state which cases passed, which were waived by an authorized customer representative and which block pilot deployment.
Frequently asked questions
How is an OEM integration test different from a factory test?
A factory test checks production quality and base product functions. The OEM integration test checks the exact branded configuration, customized firmware, protocol behavior, central platform, labels and documents agreed with the integrator. Both are useful, but they answer different acceptance questions.
Should every controller output be tested?
Test every output and input configured for the accepted model, including spare or optional channels that will be sold as available. A channel-by-channel fixture result catches mapping, labeling and board-configuration errors that a demonstration using only one signal group may miss.
Can failed cases be accepted with a waiver?
Only an authorized project representative should approve a documented waiver after the operational and safety impact is understood. Record the restriction, affected versions, corrective plan and field controls. Safety-related or tender-mandatory failures should normally block release until corrected and retested.
