Which labeling requirement is also required for Autubel devices besides sound pressure level?

• A. Stamped with electrical requirements
• B. Stamped with humidity rating
• C. Stamped with physical dimensions
• D. Stamped with serial number

Answer: (A)

Audible devices used in fire alarm systems must carry information about how they will be powered and connected, not just how loud they are. The electrical requirements on the label tell you the operating voltage, current draw, and impedance, which ensures the device can be properly driven by the control panel or power supply and will operate safely and correctly in that circuit. This helps technicians verify compatibility and prevent issues like overloading a circuit or installing a device that won’t function as intended. Humidity rating, physical dimensions, and serial number are not the primary labeling information needed to verify electrical compatibility and safe operation of Autubel devices in this context. The essential, consistent label alongside sound pressure level is the electrical requirements.
