This edition has been revised to make CO equipment more effective and reliable. Everyone from manufacturers to installers, maintainers, inspectors, and emergency personnel needs to know about updates in this edition:

• New personnel qualifications in Chapter 4 are more specific to CO systems to help ensure personnel are capable of the job.
• Revised requirements in Chapter 5 and Chapter 9 allow more than one tone for audible CO alarm signals, giving manufacturers greater flexibility.
• Reformatted inspection and testing tables in Chapter 8 align with NFPA 72®, National Fire Alarm and Signaling Code® to improve usability for inspection and testing professionals.
• New secondary power supply standby capacity of 24 hours for CO alarms and Household CO Systems provides for a longer period of power outage. This change from 8 hours to 24 hours in Chapter 9 benefits consumers by assuring longer CO alarms operation in emergencies.
• Revised provisions in Chapter 9 for CO alarms and Household CO Systems addressing distinctive alarm signals clarify that CO, fire, and other alarm signals must use different audible signals.
• New Annex C Guidelines for Emergency Responders give direct emergency responders access to resources useful during CO events.

1.1 Scope. 1.1.1 NFPA 72 covers the application, installation, location, performance, inspection, testing, and maintenance of fire alarm systems, supervising station alarm systems, public emergency alarm reporting systems, fire warning equipment and emergency communications systems (ECS), and their components. 1.1.2 The provisions of this chapter apply throughout the Code unless otherwise noted

Cabling is one of the fastest changing technologies, and Data, Voice and Video Cabling, 3rd Edition, has been updated to address all the latest developments in premises cabling, including technologies and applications in copper, fiber, and wireless cabling.
