Why this decision matters
A photograph of one device cannot establish all relevant cable, power, lighting and operating conditions.
Work through the actual task
- Repeat relevant link checks under normal closed-door conditions.
- Include metal structures, final mounting surfaces and service access.
- Ask for the proposed positions and any unresolved assumptions to be marked on a simple plan.
Worked example
The survey is conducted with all external doors standing open. This is a hypothetical example, not a completed customer installation.
The useful evidence at the end of this example is: A survey result based on realistic operating conditions.
Limits and follow-up
Do not assume wireless devices from different ranges work together. Obtain a written compatible device list for the specific panel and firmware.
If the relevant check cannot be completed, record what remains uncertain and who will resolve it before work or sign-off proceeds.
