Narrative:

We rejected our takeoff on runway 36L. After 80 KTS during take off roll; as the pilot not flying I noted the fire detection light illuminated. I announced the warning light annunciation and thereafter rejected the takeoff using company standard rejected take off procedures. I rejected for the following reasons - at the time of the warning indication; delaying the reject momentarily to troubleshoot would have resulted in us going off the end of the runway. Not rejecting posed the possibility of a subsequent engine fire with flammable hazmat on board. With adequate runway remaining for the reject and considering all other factors; I deemed it was more prudent to reject.the warning light went out during thrust reduction. The aircraft came to a full stop on the runway. Tower instructed us to hold our position and shut engines down. After engine shut down; airport operations personnel chocked the nosewheel. There were no further fire indications in the cockpit. Blown tires resulted from the rejected take off. No one was injured. No emergency was declared. We turned the secured aircraft over to maintenance.

Title: A B747-200 flight crew rejected their takeoff approaching V1 due to a Fire Detection Light. Thrust reverser deployment was delayed and multiple tires deflated due to the effects of the high speed abort.
