When playing the mod, we recommend using this dispatch system. It's based on the policy used by the actual FDNY, but obviously unit numbers are reduced into scale with the game.
This policy is based on the Structural Fire call, known as a 10-75 in ten code. If the fire escalates the highest ranking officer on scene may increase the alarm, these are the different alarms and the units required to respond.
