Voluntary Report of a Missed Daily Test of the Portable Fire Detection System On July 28, 1989, Toledo Edison submitted a letter to the NRC (Serial reduce No. 1689) describing a portable fire detection system intended to certain continuous fire watches to hourly fire vatch patrols. The letter included the planned compensatory actions for the deviations from the NFPA 72D code.

Contrary to the above, on February 4, 1990, the daily functional test was not done. The hourly fire vatch check of the local panel for alarms and to assure the phone line was connected was still being performed. On February 5, 1990, it was recognized that the daily functional test was missed. The functional test was performed, which verified that the circuit between the local panel and the control room was still functioning.
The test was missed due to a personnel error on the part of the Shift The Supervisor who inadvertently failed to ensure the test had been done.
