You can use it as a basis, but it must be revised: layouts and room uses have changed, and the standards may have too. If partitions have moved but the detectors stayed where they were, some rooms end up unprotected.

During reconstruction we survey the existing system and decide what to keep and what to replace — which saves budget.

Practical tips

  • Show the new layout to your maintenance company before remodelling.
  • Keep sound cable routes — it significantly lowers upgrade costs.
  • Update the as-built documents after reconstruction.
