Air Traffic Control Issued New Clearance; Flight Crew Rejected Takeoff
Procedure; ATC Equipment / Nav Facility / Buildings
Cleared for take off at MIA Runway 08R. At around 110 KTS Tower instructed 'B737-800 abort'. The First Officer and jumpseater repeated the command as I initiated the rejected take off. Max brakes and spoiler deployed as I went into reverse. I disconnected the auto brakes and stowed the reversers in about 3-5 seconds since we had quickly slowed to taxi speed. We cleared the runway and were told by ATC; 'Sorry ; there was a false indication of a runway incursion.' We contacted the Company and Maintenance for further assistance.  The runway incursion system should be fixed.
MIA Air Carrier departure described an ATC directed aborted take off reportedly due to an ATC equipment 'false alarm;' the reporter encouraging a readjustment of the subject equipment.
