Which sub group of fire detection in the CSI master format covers Smoke Detection Sensors?

In the Construction Specifications Institute (CSI) MasterFormat, specific sections are dedicated to various components of construction and facility systems, including fire safety elements such as smoke detection sensors. The correct designation for the subgroup that covers smoke detection sensors falls within the range concerning fire detection systems.

The designation 28 31 46 specifically pertains to smoke detection sensors, which includes various types of sensors used in fire alarm applications to detect the presence of smoke. These sensors can include ionization and photoelectric types, which are critical in the early detection of fires.

The mentioned section also outlines the requirements, performance criteria, and installation procedures that need to be adhered to for smoke detection systems within a construction project, ensuring that they meet safety standards and regulations. This is essential for fire safety design and compliance, making the selection of the right category crucial for anyone involved in drafting or following specifications for fire safety systems.

The other options reference different categories or sections that do not specifically pertain to smoke detection sensors, which is why they are not applicable in this context.
