A suburban New York City nuclear power plant's siren system has mistakenly blared out the warning, "Emergency! Emergency! Emergency!"

The ominous message rattled some of the residents of New City, about 30 miles north of midtown Manhattan. Auto shop worker Rudy Gaspari says the mechanical voice had an unsettling, post-apocalyptic overtone to it.

The voice came from an Indian Point plant siren located downtown during a test Friday, The Journal News reported.

Indian Point spokesman Jerry Nappi says the voice message "shouldn't have happened." He says plant officials have disabled the voice mechanism in the siren.

Four other sirens with faulty connections also have been fixed.

A new $15 million system is undergoing tests. It's supposed to give voice directions in park areas only.
