Hey Redsy,
Electrical Contractor mag has a good article in the Feb '03 issue on page 38 specifing some books.
It seems the "National Fire Alarm Code Handbook" by NFPA is recommended as well as NFPA's Fire Protection Handbook.
I'm interested in knowing more about that code as well, since I've been installing a bunch of fire alarm systems in commercial buildings.
By the by, how's the job market out there?
It's terrible in the commercial sector here in Denver. Haven't worked for a month...driving the wife crazy!
