On a UL compliant installation, the auxiliary outputs controlling the audible device require a minimum cutoff time of how long for a commercial burglary?

The correct answer indicates that for a UL compliant installation, the auxiliary outputs that control audible devices related to a commercial burglary situation must have a minimum cutoff time of 15 minutes. This requirement is in line with standards established to prevent excessive noise and potential disruption during an alarm event.

The rationale behind this cutoff time is to ensure that the alarm does not continuously sound for an indefinite period, which could lead to unnecessary disturbances in the surrounding area and may also cause alarm fatigue among nearby residents or businesses. A specified cutoff time also allows for any potential false alarms to be resolved without causing undue alarm to the public or law enforcement.

This standard is especially relevant in commercial environments where alarms are expected to provide security without becoming a nuisance, thereby contributing to community compliance and maintaining the efficacy of alarm systems in real situations.
