Narrative:
I was working clearance delivery during this incident. An airport vehicle was performing work on runway 1. A citation was cleared for take off runway 1. I heard the amass alarm saying runway 1 occupied and when I looked out the window the citation cleared for take off was already rotating. The local controller issued a; 'cancel takeoff clearance'; but the citation was already airborne. It does appear the amass alarmed at a time impossible to issue a cancel takeoff clearance.
