Multiple Choice

A _____ UL mark applies to products such as fire and life safety alarms.

Explanation:
UL marks show a product has been tested for safety and performance. For fire and life safety alarms, the relevant category is Signaling. This category specifically covers devices that provide alerts or notifications during emergencies—things like smoke alarms, alarm panels, sirens, and horn-strobe devices—ensuring they meet standards for reliable signaling and safe operation. The Residential mark is for general home consumer products, not specifically signaling devices. The Electrical mark covers broad electrical equipment, and the Industrial mark targets heavy-duty industrial equipment. Since fire and life safety alarms are signaling devices, the Signaling mark is the best choice.
