Not only does it list the laws, but the appendixes to the laws are in with the laws, and the reasons for the many of the laws are included in with the laws. On the other hand, the Handbook, available from the NFPA has a plus. The NFPA 72 Code Book that most people have is just a list of laws, without explanations of why the laws are there. I, however, think the extra money is well worth it. The Handbook just costs more, so most people don't spend the extra money. The Handbook is available from the NFPA alongside the regular Codebook. I learned years ago that to fully understand the NFPA Code, a person needs the 'National Fire Alarm Handbook NFPA 72'.

The difference between my copy and most other copies is that I have the Handbook. My copy shows insights into what the writers of the code were thinking when they wrote the laws shown in the Code. The NFPA 72 Code Book, however, only shows a list of laws the NFPA 72 Handbook provides a lot more information.Īs far as the NFPA requirements go, my copy of the NFPA 72 Code has more information than most other copies of the NFPA 72 Code.

There the NFPA refers to a table showing the procedure to test the different types of heat detector.

The code numbers in the code book will be different according to the year of publication, but the information can be looked up in the Index, under heat detector testing. The National Fire Protection Association 72 (NFPA 72) does go into some testing procedures for the non-restorable, spot type heat detectors.
