Subject: NY Fire Dept. Alarms From: Engine270@aol.com Date: 1995/08/06 sender: owner-FIRE-L@cornell.edu reply-to: FIRE-L@cornell.edu newsgroups: bit.listserv.fire-l On June 6, 1995, LOUMONLINO commented on why New York City does not call multiple alarms like the World Trade Center explosion or the Brooklyn Navy Yard fire last week as seven, eight or nine alarms etc. as some other communities do. The confusion started in the 1970's when FDNY went to a Computer Assisted Dispatch (CAD) system. This system was designed on the "old assignment card" structure that was in use for many years prior when bells were the primary source for alarm notifications in fire houses. On the top of each card was the borough (New York has 5 Bronx, Brooklyn, Manhattan, Queens and Staten Island) the box number and it's location. The columns were broken down by Engine Co., Ladder Co., Battalion Chief, Rescue, Squad Co., Marine Co. and other special units that may respond, the left columns were the relocating Engines and Ladder Co's and whose quarters they were going to. The rows displayed the alarms from the 1st to the 5th alarm. Every fire house had a complete listing of carda at the house watch desk for those alarm boxes that the unit responded or relocated and on what alarm. As you can see each card could covers up to a fifth alarm assignment. When a chief required an additional alarm response beyond the fifth. He would inform the dispatcher of the number of alarms to be transmitted. In return the dispatcher would transmit the requested number of alarms from one of the other boroughs and send the units to the fire. This was referred to a Boro Call or simulatneous alarm. The Broolkyn-Staten Island air plane crash, the aircraft carrier Constellation fire (also in the then active Broolkyn Navy yard) during the 1950's, the Jamaica gas explosion are just a few examples of borough calls. The Jamaica gas explosion was on Friday, January 13, 1967, occurred in the 13th Division and went to 13 alarms (who made the comment about Friday the 13th as being unlucky wasn't kidding on that day). As the card system was phased out and the computer system placed on line it was realized that it had a few "bugs" one of which was the total number of alarms for a box that the computer was set up for. In fact the chief in charge could transmitt 9 alarms but the computer could only compute the fifth alarm. Hopefully future improvements to the CAD system would correct these problems. I hope this information is helpful. Joe Walc Honorary Battalion Chief, FDNY
