Which of the following is not a requirement for a smoke control system in a high-rise building?

Automatic sprinklers
Smoke detectors in every suite
Pressurized stairwells
Dedicated generator backup

The correct answer is: Smoke detectors in every suite

A smoke control system in a high-rise building is designed to prevent the spread of smoke and to aid in evacuation during a fire. Automatic sprinklers, pressurized stairwells, and dedicated generator backup are all important components of a smoke control system. However, smoke detectors in every suite are not a requirement because they are not effective in detecting smoke that originates outside of individual suites, such as in a stairwell or hallway. Additionally, in large high-rise buildings, relying solely on smoke detectors in each suite may result in delays in detecting and responding to a fire, which can be dangerous. Therefore, it is important for a smoke control system to have multiple detection methods, including centrally located smoke detectors and manual fire alarms. This ensures that any signs of smoke or fire are immediately detected and addressed.
