What does a remote annunciator indicate?

A remote annunciator serves as a critical component in fire alarm systems, providing important visual and audible signals to indicate the status of various components in the fire detection system. When it displays an off-standard or abnormal condition, it alerts personnel to potential issues such as alarms being triggered, system errors, or the presence of smoke or heat. This information is vital for responders to take appropriate action promptly, ensuring safety and compliance with fire safety protocols.

The other options do not accurately reflect the function of a remote annunciator. While a normal operational status of the fire system can be indicated, this does not encompass the primary purpose of the annunciator, which is to signal discrepancies. Although it may signal when a fire has been extinguished, it primarily focuses on abnormalities. Additionally, indicating a malfunction in the sprinkler system is too specific and not the primary role of the remote annunciator.
