Abstract: The system and method for locating building priority systems are disclosed. An EAS or RFID tag is applied to plumbing fixtures, heating units, hazardous materials, electrical junction boxes, outlet boxes and/or wiring systems within walls, floors, ceilings. A RFID reader sends an interrogation signal when scanned over walls, floors, or ceilings that causes the tag to emit a response signal. The RFID reader displays a LED and/or LCD readout to pinpoint priority systems for the purpose of residential, commercial, and industrial construction and maintenance that may not be visually obvious.
