Re: CO sequence of operation
When I get involved in the design of a facility that will have special systems for fire alarms, security alarms, or CO alarms, my activities are generally limited to showing devices on the plans, and leaving the detail design to the specialty systems contractor. The company chosen to provide the fire alarm system, for example, is directed (by the project specifications) to provide drawings and cut sheets of their own system?s design.
So my question would be, have you asked a local vendor?s representative for assistance?
