What do you mean "code"?

I'm just going to honk down on that thing till someone shows up!

NYPD used the Morse code signal for a numeral, using the whistle blasts, as a substitute for the radio Ten-Codes, ignoring the "ten" but sending the second numeral only, back in the days before portable police radios, so that a Radio Motor Patrol unit (RMP) could relay the whistle signals from an isolated officer in pursuit back to the main dispatch.

Old system was used as backup after 9/11 when the Towers collapsed and the police radio system was down until the backup system became operational.
