Same thing in Hartford too. I've heard them say both Code 10 and 10-5, for silence on the channel.andy404ns said:In the PD where I live, Code 10 is used for radio silence. I hear it a lot on suspected break ins and other investigations where the perp may still be in the area. Andy
Many thanks for the excellent answer and url's!!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.
