Why this decision matters
A photograph of one device cannot establish all relevant cable, power, lighting and operating conditions.
Work through the actual task
- Survey the equipment and changes in surroundings.
- Identify inaccessible components and unrecorded additions.
- Ask for the proposed positions and any unresolved assumptions to be marked on a simple plan.
Worked example
The system record no longer matches the installed devices. This is a hypothetical example, not a completed customer installation.
The useful evidence at the end of this example is: A corrected inventory and a list of checks still requiring access.
Limits and follow-up
Arrange tests with the monitoring provider first where applicable. Do not trigger a response service without following the agreed test process.
If the relevant check cannot be completed, record what remains uncertain and who will resolve it before work or sign-off proceeds.
