Fixed automatic dry chemical extinguishing systems are required to be installed according to what?

Fixed automatic dry chemical extinguishing systems must be installed following both the applicable standards, such as the NFPA 17, and the manufacturer's installation manual. This dual requirement ensures that the system is not only compliant with established safety and effectiveness guidelines but also tailored to the specific design and operational parameters provided by the manufacturer.

Adhering to the NFPA standards establishes a baseline of safety and effectiveness, while the manufacturer's instructions provide critical information specific to the components and configuration of the system in question. This combined approach is essential for ensuring both performance reliability and the safety of individuals and property in the event of a fire.

While only relying on the manufacturer's design manual can lead to potential oversights regarding broader safety standards, and using any standard available lacks the specificity and relevance needed for effective installation, compliance with recognized standards along with manufacturer guidelines is crucial for optimal functionality and safety.
