This will continue forever and the drum will never move again. For this system to work that timer must have some kind of algorithm built in, which will either be a delay or something that over rides the sensor until the circuit closes again.
For the system to be reliable a simple a delay won't work. If it's an over ride that's a pretty cool little system. How much would the whole system cost, built and ready to go?

It would be a fairly easy DIY mod to a 4 way or 2 way, still will cost $39
