What is the exception to the quarter smoke detection requirement for hotels and dormitories?

• A. Buildings protected by an approved supervised automatic sprinkler system
• B. Buildings with a single occupant
• C. Buildings with no electrical power
• D. Buildings with metal doors and frames

Answer: (A)

The key idea is that an approved supervised automatic sprinkler system can replace the need for quarter smoke detectors in hotels and dormitories. When a building has a properly installed and monitored sprinkler system, it provides active fire suppression that reduces the risk to occupants, so the requirement for detectors in every quarter isn’t needed as an additional safeguard. The other scenarios don’t offer the same level of protection or compliance justification: a single occupant doesn’t cover the whole building’s risk, loss of electrical power doesn’t create an exemption, and metal doors/frames don’t address the detection requirement. So the exception applies specifically when the building is protected by an approved supervised automatic sprinkler system.
