When must smoke detectors be installed?

Smoke detectors must typically be installed at a specific stage in the construction process to ensure their proper functioning and effectiveness in case of fire. Installing them after the final construction cleanup aligns with best practices, as it allows for any necessary finishing work to be completed without risking damage to the detectors during the construction process.

By waiting until after the cleanup, the installation can ensure that the detectors are free from dust, debris, or any other substances that could impede their performance. Additionally, placing them at this point often aligns with building codes and safety regulations, which may specify that detection systems must be installed in the final stages of construction to guarantee safety compliance before occupancy.

This approach minimizes the risk of needing to replace or reposition smoke detectors due to disturbances during earlier phases of construction, thus making it both a practical and code-compliant choice.
