  1. I have an occupancy coming in that is Around 7000 square-foot repair type shop that has machines with It, ( They repair drills) the building is one story with multiple egress areas. Should I push for a alarm system due to having machines

    I think less than 25 employees will working there according to the code above they are not required but I want to push it just because of buildings around it are very close and one is up against it.



    50 people working there I was just wondering if I should push for a fire alarm system
