How must the special residential sprinklers be installed?

The special residential sprinklers must be installed in accordance with their listing limitations because these limitations provide specific guidelines that ensure the proper functioning and safety of the sprinkler system. Each type of sprinkler has been tested and approved for certain installation parameters, including orientation, distance from obstructions, and pressure requirements. Following these guidelines is crucial for the system to operate as intended in the event of a fire.

Adhering to the listing limitations ensures compliance with both manufacturer specifications and the standards set forth by regulatory bodies. This helps to maintain the efficiency of the sprinkler system, ultimately protecting life and property. While other options might suggest different installation methods, they do not provide the necessary assurance that the installation meets the required safety and efficacy standards set by the manufacturers or relevant codes.
