Before its implosion in "Live Together, Die Alone, Part 1", the Swan contained a 108-minute countdown timer. The timer was reset by entering the Numbers into the station's computer and pressing the Execute button. Failure to enter the Numbers within the last four minutes of the countdown cycle triggered an alarm, which lasted until the timer reached zero. On completing the countdown, the timer's numbers were replaced by red and black Egyptian hieroglyphics while simultaneously a recorded voice repeated "system failure" continuously over the station's speaker system.
