What is the requirement for visual notification appliances used in special environments?

• A. Must be listed for the intended application
• B. Must be certified for the environment
• C. Must have a UL listing
• D. Must be approved by the AHJ

Answer: (A)

Visual notification appliances used in special environments must be listed for the intended application. Listing means the device has been evaluated and approved by a recognized testing laboratory specifically for that particular use and environment, ensuring it can perform reliably under the conditions present (like humidity, temperature, dust, or other environmental factors). This requirement ensures the appliance’s performance is appropriate for the exact setting, not just generally listed or certified. While AHJs may review and approve installations, the essential baseline is that the device is listed for the intended application.
