Narrative:

On takeoff, just seconds after the power was set, we had a lavatory smoke warning light on the central warning panel illuminate and then went out. We aborted the takeoff. We told tower we aborted, we taxied off the runway, we communicated with tower, then ground. We told them no assistance was required and requested to taxi back for another takeoff. The lavatory was inspected and the warning system were tested. The light did not come back on anytime during taxi and the second takeoff.
