Why this decision matters
Equipment age alone does not explain the fault, the benefit of replacement or the limits retained after repair.
Work through the actual task
- Request the diagnosis and a targeted repair option.
- Compare the upgrade against specific support, coverage or usability limits.
- Compare total scope and ongoing costs rather than a panel or recorder price alone.
Worked example
A single failed detector prompts a whole-system replacement offer. This is a hypothetical example, not a completed customer installation.
The useful evidence at the end of this example is: Separate repair and replacement scopes with their actual benefits.
Limits and follow-up
Do not open mains powered equipment or defeat tamper switches. Arrange a qualified service visit when a fault needs internal inspection.
If the relevant check cannot be completed, record what remains uncertain and who will resolve it before work or sign-off proceeds.
