Local Loop Facility Tour


A coded door lock (Simplex) secures the hatch.  Opening the access hatch activates an intrusion alarm which results in the monitoring center being notified via telemetering equipment that the hatch has been opened.  A view of the status lights indicating when it is safe to descend and the ladder leading down to the interior of the CEV are shown in the picture.  Employees must check these indicators before entering.  Upon entering the vault, employees must call the monitoring center and provide appropriate identification and indicate the purpose of their entry.
