A compilation of alarm sounds from the former World Trade Center Complex. Consisting of the Cerberus Pyrotronics alarm, and the Firecom 8500 alarm. More info below: WTC 3 Marriot Hotel alarm video: These sound effects are based on footage from the sept. 11 attacks, the subsequent NIST NCSTAR1-4C “Fire Alarm Systems“ report, research within the “World Trade Center Fire Alarm System History“ topic on TheFirePanel forums, and from the Firecom patent. The sounds and information are generated and/or gathered from with the best available research to me. Some inaccuracies might occur. Known inaccuracies -The Wheelock 34t alarm generator shown for the Cerberus Pyrotronics alarms, and as shown within the Port Authority “World Trade Center Fire Safety Instructions“ video is not a speaker box. These would have been Wheelock E70 speaker strobes. -WTC 3/Marriot Hotel's alarm is an Edward's system whoop alarm
