What describes restrictions on device installation based on listings?

• A. Special sprinklers
• B. Listing limitations
• C. Satisfactory Performance
• D. Discharge Characteristics

Answer: (B)

The main idea tested here is how equipment gets approved for use and what that approval allows. When a sprinkler or other device is listed, a recognized testing laboratory has evaluated it and specified not only that it works, but also where and how it can be installed. Those specific conditions are called listing limitations. They set the boundaries for installation—things like what systems the device can be used with, acceptable piping, spacing, environmental conditions, orientations, and other installation details. If you install the device in a way that isn’t covered by its listing, you’re outside what the approval allows, which can compromise safety and compliance. So, listing limitations describe the restrictions on installation based on the device’s listing. The other terms don’t capture that idea: special sprinklers refer to unusual types, satisfactory performance is about passing tests, and discharge characteristics deal with how water flows rather than where you may install the device.
