When should smoke detectors be installed during the construction process?

The installation of smoke detectors is most appropriately completed after the final cleanup of all trades. This timing is important for several reasons. Firstly, the final cleanup ensures that debris, dust, and potential contaminants from the construction process do not interfere with the operation of the smoke detectors. Smoke detectors are sensitive devices, and a layer of dust or debris could affect their ability to function properly. Additionally, installing detectors after all trades have completed their work minimizes the risk of damage to the detectors that can occur during ongoing construction activities.

Installing smoke detectors too early in the construction process, such as during the installation of walls or before the ceiling is in place, increases the likelihood of them being damaged or contaminated. Waiting until after the framing inspection is also not ideal, as it does not fully account for the cleanup that follows the work of various trades, which could leave residual materials that could impede the detectors' effectiveness. Thus, timing their installation for after the final cleanup ensures optimal performance and reliability when they are needed most.
