It isn’t warm. It isn’t fuzzy. From its extraterrestrial presence on the Bronx skyline to its security-state name, PSAC II is not in the least bit neighborly.

Yet it may save your life someday.

PSAC II is New York City’s second Public Safety Answering Center, where more than 11 million emergency 911 calls are taken by the Police and Fire Departments each year. Beginning next month, it is to supplement PSAC I at 11 MetroTech Center in Downtown Brooklyn.

When necessary, PSAC II can handle the work of both centers. It is intended to be virtually impregnable and, if needed, self-sufficient for three days at a time. No food deliveries. Nothing. The fuel supply for its generators can last even longer.

Time will tell whether it fulfills these promises. The city’s 911 response system has not been without problems in the past.
