Regional Jet 200 ER/LR (CRJ200)
Flight Crew Air Transport Pilot (ATP)
Aircraft Equipment Problem Less Severe
Flight Crew Rejected Takeoff; General Maintenance Action
Aircraft; Procedure
While taxiing for runway; two status messages were posted. Ground (GRD) spoiler fault; Flight spoiler fault.  A Master Caution was also posted as GRD spoiler.  Maintenance was notified and crew was advised to return to gate.  Upon return to gate; maintenance personnel replaced the faulty electrical systems and aircraft was returned to service.  Aircraft taxied back to runway.  All pre-takeoff checks were normal. On the takeoff roll after 80 KTS and before V1 approx. 120 KTS a master caution was posted with a takeoff configuration and ground spoilers.  The Captain called for an abort and assumed control of aircraft.  The aircraft was brought to a stop on the runway; and exited under control to a taxiway. ATC was notified and a call to the flight attendant placed to make sure that all was ok in the cabin.  The aircraft was taxied back to a gate.  The right brakes were smoking and the Brake temperature Monitoring System (BTMS) readings were 8.  Maintenance was notified.  A walk around was completed along with all appropriate checklists.  The only abnormal aspect was the smoking brakes; that subsided with time. A master caution for a Takeoff configuration at 120 kts with possible ground spoiler deployment. The Captain did a great job in bringing aircraft to a safe stop.  I believe that when we have flight control faults the aircraft should undergo deeper checks prior to being released for service.  Also during training we should include a high speed abort in simulator training for this exact problem that we experienced.
A CRJ-200 First Officer reported the Captain decided on a high speed rejected takeoff when they received master caution warnings of 'Takeoff Config' and 'Ground Spoilers.' The reporter stated these items were the subject of maintenance attention prior to takeoff.
