Shortly After 8:46 a.m. September 11, 2001: Automated Announcement in WTC’s North Tower Instructs Workers Not to Evacuate

An automated announcement is reportedly activated in the North Tower of the World Trade Center, advising workers to stay in their offices rather than evacuate, although a senior official will later dispute the accounts of security officers who describe hearing it. The announcement is heard by workers in the Port Authority’s Security Command Center (SCC) on the 22nd floor of the North Tower.
Automated Announcement Heard by 'a Lot of People' - The recorded female voice that makes the announcement usually comes on automatically in situations such as when a sprinkler is loose, telling people to return to their offices, according to Hermina Jones, a security guard in the SCC. Jones will recall that the automated recording now comes on, apparently after being activated by the impact of Flight 11 hitting the North Tower. She will say that “a lot of people listened to that and went back to their offices. When tenants called me on the intercom, I told them to ignore it and take Stairway A.” Jones will add, “You could hear [the recording] in the background, telling them over and over, ‘Please go back in your office.’” Nancy Joyner, a security supervisor, also notices the recorded announcement. “Whenever there is smoke, sometimes the alarm will trigger, and that’s when you heard [the recording],” she will say. She will add, “That day [i.e. September 11], the recording came on.”
Port Authority Official Says There Are 'No Automated Announcements' - However, Alan Reiss, the director of the World Trade Department of the Port Authority, will dispute the recollections of Jones and Joyner, and claim that no recording goes off. He will state, “There were no automated announcements used anywhere in the World Trade Center, as such recordings are not permitted by fire codes.” Furthermore, Reiss will state, “no messages of any kind—live or otherwise—could be heard over [the North Tower’s] public address system, which was severed by the impact of the first plane.” [Newsday, 9/10/2002; Newsday, 10/8/2002] The 9/11 Commission Report will indicate, however, that announcements might be heard in a few areas of the North Tower. “Because of damage to building systems caused by the impact of the plane,” the report will state, “public address announcements were not heard in many locations.” Around the time that the automated announcement is reportedly going off in the North Tower, an announcement is made in the South Tower, advising workers to stay in their offices, instead of evacuating (see (8:50 a.m.) September 11, 2001). That announcement, though, is made by a deputy fire safety director, rather than being a recorded message. [9/11 Commission, 7/24/2004, pp. 286-288]
