If I accept fin aid award for backup school, does that affect funding??

I am currently in limbo with two schools.  NCCU, I have to take their special program next week and wait to see if I get accepted.  In the meantime, FCSL is my backup and as far as they are concerned, I am going there.  I already paid the first deposit and today I got my award letter.  They said I have to sign it and a promissory note within 10 days.  If I do this, does this cut me out of getting funding once I get into NCCU??  I need to keep FCSL as my backup, but also be able to get aid for NCCU.  Does the gov't allow you to get multiple awards, at least until you get one disbursed?
