Final answer:
The AHJ may require additional annunciators (option 1) when information displayed on a combination system annunciator is excessive. Additional annunciators help to efficiently manage and display information, reducing overload on a single screen.
Step-by-step explanation:
The question pertains to a situation where the Authority Having Jurisdiction (AHJ), which is an organization or individual responsible for enforcing the requirements of a code or standard, may require modifications when information displayed on a combination system annunciator becomes excessive. A combination system annunciator is a centralized display interface for monitoring the status of a fire alarm system and other building systems. The correct response to what the AHJ may require in such a case is: 1) Additional annunciators.
Additional annunciators help in managing and displaying the information efficiently, ensuring that the data can be accurately monitored and responded to in an emergency. This approach allows for sections of a system to be displayed separately, hence reducing information overload on a single screen. Though the other options, such as additional control panels, additional power supplies, and additional fire alarm devices, might be applicable in different contexts, they do not specifically address the issue of excessive information on an annunciator display.
