Smoke detectors shall not be installed until the final cleanup of the jobsite has occurred.

Smoke detectors shall not be installed until the final cleanup of the jobsite has occurred.

• A. False
• B. Only after inspection
• C. True
• D. Not required until occupancy

Answer: (C)

During construction, a detector’s performance can be compromised by dust, paint fumes, solvents, and debris, and its mounting or wiring can be damaged by ongoing work. Installing smoke detectors after the final cleanup ensures the space is clean, the detectors are properly placed, wired, and tested, and they will operate reliably once the space is occupied. This avoids nuisance alarms and false activations that would occur if detectors were installed while the site is still under construction. So the statement is true. Installing earlier would leave the system unprotected or prone to false alarms, and waiting until occupancy would delay essential protection.
