There is a box mounted on the wall with the contacts in it I think. I couldn't get to it to see much because they were installing the fire system. the guy installing the piping didn't know much except that he thought it needed a 30 amp breaker, turn on the exhaust fan and turn off the supply fan. I'll be there at 7:30, They said the building inspector not to be there until at least 10:00. "We need it done as fast as you can, you work and we will get whatever parts you need" they said.
