I'd assumed it would be a timer.
So to get one to detonate manually, you're going to have to simulate the 40-ish Gs of a launch, the delay of flight to allow the safety to disengage (but not so long that the self-destruct happens), and be far enough away to not get injured by the explosion. That's a challenge.
