Default Shutting down diesels

Due to Transports Canada regulations we have had to install a fire extinguisher system in the engine compartment. There is a control panel with relays that is supposed to cut the engines when there is a fire. The problem I have run into is that cutting ignition power will not stop the engines. To stop the engines I have to turn the key all the way to the left. The key starts at 12 OClock, goesa to 2 Oclock for preheat and 3Oclock for starter. Once running you have to turn the key to about 10 Oclock to shutoff. I have the use of a relay to shut the motor off and am now wondering how can I stop the engines with it.

First diesels don't have ignition, fuel ignites due to being compressed. Shutting down a diesel requires the fuel flow to be stopped which is typically done by a solenoid in the fuel supply line. You will need to wire the relay to interrupt the solenoids power.
