Bigruss said:In Greenwich for both PD and FD, "code 10" means respond directly not using emergency lights and sirens. I have also heard PD dispatch use "code 10-1" which I am pretty sure means use lights and sirens as necessary to respond rapidly but discreetly. (for a burglary in progress for example)
Code 20: Respond using emergency lights and sirens continuously.
Code 30: Respond when available.
