What does a supervisory signal need to be addressed?

A supervisory signal indicates that a monitored condition within the fire alarm system requires immediate attention. This could involve scenarios such as the failure of a component, an issue with power supply, or failures in communication with devices. Addressing these supervisory signals promptly is crucial for maintaining the efficacy of the fire alarm system, ensuring that it functions correctly and can be relied upon in the event of an emergency.

Taking immediate action is necessary because delays in addressing supervisory signals can lead to larger issues or may prevent the system from alerting occupants in a critical situation, thereby jeopardizing safety. Other options may not align with the immediate needs and protocols surrounding supervisory signals. For example, while documentation (such as mentioned in another choice) is indeed important for record-keeping, it does not address the immediate risks involved. Similarly, seeking approval from external parties or disabling the system are actions that can compromise safety rather than uphold the integrity of the fire alarm system.
