The term "Box" comes from the old street boxes- the electromechanical alarm boxes that would be found on street corners, on large buildings or important buildings (hospitals, schools, etc). Each box is assigned a number- for example, "1234." Inside the box (which works very simularly to a telegraph) is an electromechanical telegraph- A spring-powered motor which turns a notched wheel (in this case, a wheel with 1 notch, then 2, then 3 and then 4 notches) which in turns opens and closes a set of contact points (much like the points on an older gasoline engine with a distributor). The points open and close once, twice, three and then four times, signalling box "1234" to the dispatcher. The dispatcher then looks in the card file (like a library's card file) which has all the boxes numerically listed. The card for any average city could look something like this:
1234 THIRD AND MAIN 1234
ENG CO's TRK CO's Bn Ch. RS. Div. Transfers
First Alarm 3, 7, 9, 11 1, 3 1 2 1 E4 to 9
Second 12, 19, 6, 4 2, 7 2 1
Third 16, 1, 4 Snkl 1 4
Here's the first alarm for Philly 7569, Ascot Place and London Road (I acquired the box about 10 years ago)
7569 Ascot Place at London Road 7569
Eng Co's Ladder Co's Bn. Rs. Div.
First Alarm 58, 62, 22, 71 34, 31 13, 12 1 2
Anyways you get the idea......Though most major cities have since done away with the street boxes themselves, they have retained the box numbers and the run cards. So if someone calls in to 911 reporting a fire at "2331 Main Street" The dispatcher enters the address.....the computer chews on the address and the nearest box pops up.....If you are listening to FDNY, you will hear something like....."In the Bronx, a Phone Alarm for box 4612 (Bronx Park Ave at E180 St.) for the reported address xxxx East One Eight Oh street, reported to be a fire in the private dwelling......"
That means someone called 911 via telephone ("Phone Alarm") reporting a fire in the private dwelling located at xxxx East 180 St. The nearest "box" is 4612.
Oh, and by the way, if you listen to FDNY and hear "ERS alarm on box 2367, for the address xxxx........" That means the alarm was recieved via ERS Box- These are boxes on the streets of NYC that you press a button, and you actually speak to a dispatcher.
Does any of this make sense?
