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

The correct answer is associated with the Underwriters Laboratories (UL) standards that pertain specifically to burglar alarm units. UL 365 is the standard that is recognized for the testing and certification of burglar alarm equipment. This standard covers essential safety and operational components to ensure that alarm systems meet industry safety requirements and perform reliably in the event of a burglary.

In contrast, UL 1981 primarily focuses on signal processing equipment, UL 611 is related to the safety of electrical equipment for use in alarm systems, and ANSI/SIA DC-09-2007 pertains to power supply units used in alarm systems but does not cover the broader functionalities of burglar alarms. Understanding these distinctions helps clarify the specific application of UL 365 in the context of burglar alarm systems and ensures that they have undergone adequate testing for safety and performance.
