What should be listed on the nameplates of notification appliances?

• A. The serial number
• B. The installation date
• C. Electrical requirements and rated audible or visual performance
• D. The manufacturer address

Answer: (C)

Nameplates on notification appliances carry the essential data needed for proper installation and operation. They must clearly show the electrical requirements—such as the supply voltage and current draw—so the device can be wired to the correct power source and driven by the appropriate control circuitry without overloading the circuit. They also specify the rated audible or visual performance, meaning the device’s sound output for horns or the light output (candela) for strobes, at specified conditions. This information lets the installer verify that the device will meet required life-safety performance and comply with applicable standards and listing. Details like a serial number, installation date, or manufacturer address aren’t needed for the device’s operation and aren’t the primary items used to confirm proper performance, even though some of these may appear elsewhere for documentation or service.
