Which sub group of fire detection in the CSI master format covers Fire Alarm Pull Stations?

The correct choice reflects the specific classification within the Construction Specifications Institute (CSI) MasterFormat that pertains to fire alarm pull stations. This classification is organized to facilitate detailed descriptions of different components in fire alarm systems in a way that aligns with industry standards.

The designation "28 31 53.13" specifically refers to manual fire alarm pull stations, which are devices designed for activation of the fire alarm system by individuals in an emergency situation. This subgroup addresses features, installation, and requirements of these devices, making it essential for ensuring compliance with safety regulations and effective emergency response strategies.

Understanding this categorization helps stakeholders—such as contractors, architects, and engineers—organize specifications clearly and concisely, ensuring that all necessary components of a fire alarm system, including manual pull stations, are considered for installation and compliance during a project.
