Which UL Standard covers Police Station Connected Burglar Alarm Units and Systems?

The correct answer is UL 365, which specifically addresses the standards for Police Station Connected Burglar Alarm Units and Systems. This standard outlines the requirements for the performance, reliability, and operational integrity of alarm systems that are directly connected to police stations. These systems are crucial for ensuring timely law enforcement response to burglary alarms, thereby enhancing public safety.

UL 365 covers multiple aspects of the alarm units including performance testing under varied conditions, ensuring that alarms are not only activated accurately but also that they communicate effectively and securely with police monitoring stations. This standard is particularly significant as it helps establish guidelines that manufacturers must follow to ensure their systems meet necessary safety and operational protocols.

In contrast, the other options do not pertain specifically to police-connected alarm units. UL 611 is generally related to line-voltage electric burglar alarms; UL 1981 focuses on specific testing methods for alarms in business systems; and ISO 9000 is a series of quality management standards that are not specific to burglar alarm systems. Therefore, UL 365 is the definitive standard for those systems directly linked with police station responses.
