Why this decision matters
A powered-on indicator does not prove that the detection, recording, release or reporting outcome still works.
Work through the actual task
- Check the exact manufacturer-approved battery requirement.
- Arrange correct replacement and an authorised device-status check.
- Assign each follow-up to a person and book qualified service for internal electrical work.
Worked example
A device repeatedly reports low battery after unsuitable cells were fitted. This is a hypothetical example, not a completed customer installation.
The useful evidence at the end of this example is: Battery type/date and confirmation that the relevant warning has cleared.
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.
