Earlier today I got an email asking about the use of Hot and Cold Calls in Chatham County EMS dispatches. This is something I should have posted about some time ago but it didn't come to mind.
Basically Hot Call and Cold Call replaced Code 3 and Code 1 after Chatham County transitioned to plain English dispatching. A Hot Call is the old Code 3 response with lights and siren activated. A Cold Call is the old Code 1 response with no lights and siren.
You'll hear Metro dispatch use the terms Hot or Cold Call in their initial dispatch as well as by MedStar and Southside when they re-dispatch 911 calls.
