Please help - please!  I have a fire alarm installed outside of my dorm (for when lightning strikes the trees).  Well, it struck, and the fireman showed up...and left.....and showed up again.......and left......he's still showing up and leaving (at least he doesn't charge me every time he shows up like it was a prank or something).
 
The fire went out on its own, but the alarm won't shut off.  OMG it's really obnoxious.  Can anyone help me fix this?  Oh, yeah, I did try to delete the alarm, but that didn't solve the problem.
