Ok so I got thrown into doing this kitchen hood. Not much info given. Basically I have a exhaust fan, make up air, and lights.
Doing research on here I have figured basically everything needs to shut off except the exhaust...which could also depend on local requirements.
Now my question is how exactly are the make up air and exhaust supposed to be controlled? Basically is it just a on/off PB on the wall that enables both units for normal operation? I can figure out the controlling to be inter connected with the fire suppression without much problems I am just actually unsure of the normal operation side of it.....never done one before. Also I have noticed you guys talk about using shunt trip breakers to kill power to make up air, lights etc, but could I just achieve the same results with contactors....or are the shunt trips needed?
