What is the function of a remote annunciator?

• B. To provide backup power.
• C. To activate the HVAC.
• D. To display the status and location of alarms or troubles away from the main control panel, aiding responders.

Answer: (D)

A remote annunciator is used to display the status and location of alarms or troubles away from the main control panel, helping responders quickly understand where an issue is and what type of condition is present. It mirrors the system’s zone indicators in a distant, easily viewable spot, so staff can assess and coordinate a response without fetching the main panel. This is especially helpful in large buildings or control rooms where the main panel isn’t readily accessible.

It doesn’t deliver alarms to external agencies—that function is handled by the panel or a monitored interface. It also isn’t a power backup device, nor does it control HVAC; those roles are separate from what a remote annunciator does.
