This is what happens if you are in quarters, the tones go off and the run info comes in on the computer in the housewatch, whoever is doing ''the watch'' reads the run info over the firehouse PA,(example, Engine goes Truck goes first dues, 1234 maple street, for a report of smoke in the hallway), then the guy who has the watch would 10-4 the run on the teleprinter and ring out the bells for whoever is going. Then whem the company's are en-route they get info via the MDTs, such as wich company is 10-84, if the box was 10-75'd or maybe second sources that came in and information on the buillding or structure etc.
