What type of smoke detection system shall be provided at all hotels and dormitories?

• A. A quarter smoke detection system
• B. A full building smoke detection system with ionization sensors
• C. Only portable smoke detectors in some rooms
• D. No smoke detectors required

Answer: (A)

In hotels and dormitories, the required fire protection approach is a zone-based coverage that provides automatic detection without needing a full-building network. A quarter smoke detection system means detectors are installed in designated zones (roughly one quarter of the building’s areas or per floor/wing) to give early warning and support safe evacuation while keeping installation costs reasonable for large occupancies. This level of coverage is the minimum stated for these types of buildings in the context of this material, balancing safety with practicality.

Compared to a full building system, the quarter system is less extensive but still meets the occupancy’s life-safety intent described in the material. Relying only on portable detectors in some rooms leaves gaps in protection and is not sufficient for a licensed alarm system requirement. Having no smoke detectors at all would fail to meet safety regulations.
