What should always be performed after replacing a defective detector?

After replacing a defective detector, it is essential to test the new unit to ensure that it functions correctly within the fire detection system. This step verifies that the replacement has been properly installed and integrated, and it confirms that the detector is operational and capable of identifying fires or abnormal conditions as designed.

Testing can help identify any issues with installation or compatibility and ensures that safety protocols are properly upheld. It is a critical step in maintaining safety within powerplant operations, ensuring that the detection system continues to provide reliable and timely alerts in the event of a fire.

While notifying an insurance company, installing a backup system, or updating system software may be important in certain contexts, they do not directly address the immediate need to ensure that the fire detection system is functioning as intended after a component replacement.
