Ron- I'll check out the MBC tomorrow and let you know what it says. I think about the detection system under the hoods in kitchen. They are not designed to sound any audible alarm or visual alarm. I know the HVAC people have a requirement in their code for smoke detectors in the duct work to sound an alarm both visual and audible if the unit is of a certian size. The mechanical people need to have their own alarm system or it has to be tied to the fire alarm system if there is one in the building.
