1. A method for monitoring a fire detection system, the method comprising:
surrounding a wire of the system with an induction coil;
sensing current in the wire with the induction coil;
communicating data of the sensed current from the induction coil to a diagnostic tool; and
decoding the data to interpret communications sent through the wire, wherein the communications are commands from a panel of the fire detection system or are responses from a detector of the fire detection system.
