It's "Badger" or "Range Guard", not "Badger Guard". Which fan is connected to the system, exhaust or make up? If it's exhaust, why is it connected? These systems are listed for exhaust on or off, and usually you want them on to remove heat and smoke from the kitchen during the fire event. If it's make up air, most codes require that the make up air shut down on system activation. You don't want to bypass this. What's the big deal? The fan might be out of action for 10 or 15 minutes during testing.
