What types of buildings are typically required to have fire alarm systems?

Fire alarm systems are essential for various types of buildings where the potential for fire-related incidents poses a significant risk to occupant safety. Hotels, shelters, and hospitals are among the most commonly required facilities to have sophisticated fire alarm systems installed due to their high occupancy levels and the diverse needs of the individuals within them.

Hotels and shelters often accommodate large numbers of guests who may have varying needs for assistance during an evacuation. An effective fire alarm system provides immediate alerts, ensuring that occupants can respond quickly and safely to emergencies. Hospitals are particularly critical, as they house patients who may be unable to evacuate without assistance. A reliable fire alarm system is vital in facilitating timely alerts and coordinated evacuation procedures.

Other types of buildings like residential buildings, schools, and universities, while they may also have fire alarm requirements, do not typically encompass the same range of risks and occupant needs as hotels, shelters, and hospitals. Manufacturing plants, while they do have distinct safety requirements, often focus more on industrial safety measures and may not have the same level of stringent requirements for fire alarm systems when compared to the life-safety profiles of the buildings listed in the correct answer.

Thus, the requirement for fire alarm systems in hotels, shelters, and hospitals aligns with national and local building codes
