Which of the following actions is necessary for the installation of fixed automatic dry chemical extinguishing systems?

The installation of fixed automatic dry chemical extinguishing systems must adhere to the manufacturer's design and listing requirements. This is crucial as manufacturers provide specific guidelines that ensure the system functions effectively and safely in a variety of conditions. These guidelines include installation techniques, placement of equipment, and the types of dry chemical agents to be used. By following the manufacturer's specifications, you ensure that the system is compliant with safety standards, performs optimally, and maintains reliability in an emergency situation.

This adherence is part of a broader commitment to safety and efficacy in fire protection systems, ensuring that all installations are done methodically and backed by the engineering and testing that the manufacturer has performed. It significantly reduces the risk of malfunction or failure when a fire does occur.
