Which UL standard is associated with the testing of burglar alarm units?

The correct choice related to the testing of burglar alarm units is UL 365. This standard specifically addresses the requirements for burglar alarm systems, including their performance, mechanisms, and user interface features. Under UL 365, various aspects of alarm systems are examined, ensuring that they meet certain safety and operational criteria to function effectively in detecting intrusions and alerting users.

UL 1981 pertains to different types of alarm systems and does not specifically focus on the testing of burglar alarm units as UL 365 does. The UL 611 standard relates to the operational requirements for emergency signaling systems. ANSI/SIA DC-09-2007 is a technical standard that focuses on the general requirements for physical security. Therefore, while these other standards may address various aspects of security and alarm systems, UL 365 is the designated standard specifically tailored for burglar alarm unit testing, making it the most relevant choice for this question.
