According to the Life Safety Code, what features should a LIM include?

A LIM, or Line Isolation Monitor, is a crucial device in healthcare settings, especially in areas where electrical equipment is used on patients. The Life Safety Code outlines specific features that help ensure the safe operation of electrical equipment and minimize the risk of electrical shock.

The correct answer highlights the requirement for a LIM to include both an audible alarm and red and green indicator lights. The audible alarm serves as an immediate alert to healthcare staff when there is a fault or potential electrical issue, ensuring that they can take swift action to address the problem. This auditory signal is vital in a busy healthcare environment where visual cues alone may not be sufficient to capture attention.

The colored indicator lights enhance the system's functionality by providing a visual indication of the status of the electrical isolation. For example, a red light typically signifies a fault condition that needs attention, while a green light indicates that the system is operating normally. This combination of auditory and visual alerts allows for more effective monitoring of the electrical safety of medical equipment.

In contrast, the other options may include elements that contribute to alarm systems or indicators but do not encompass the full standards required for a LIM as specified by the Life Safety Code.
