In special environments, visual notification appliances must be what?

• A. Certified by the installer
• B. Compatible with any power supply
• C. Listed for the intended application
• D. Dimensioned to fit space

Answer: (C)

Devices used in special environments must be listed for the intended application because listing shows the appliance has been tested and approved to operate safely and effectively under those exact conditions. The listing verifies that the visual notification appliance meets the necessary environmental, mounting, electrical, and performance requirements for that specific setting, ensuring reliable visibility and operation during an alarm. Certification by the installer isn’t enough to guarantee this safety and compatibility, and simply being compatible with any power supply or sized to fit a space doesn’t address environmental exposure, performance, or code compliance. Listing for the intended application provides the necessary assurance that the device is suitable for the environment and installation.
