NFPA 3, Recommended Practice on Commissioning and Integrated Testing of Fire Protection and Life Safety Systems, is ready for use. The proposed standard generated a lot of discussion, debate, and controversy. An extensively debated issue involved which technical committee is responsible for developing the acceptance testing requirements for individual fire protection systems and/or features. Many of the fire protection system technical committees filed comments on the proposed commissioning standard, questioning whether the NFPA 3 technical committee was operating outside of its scope and trying to mandate requirements that fall under the authority of the existing individual system standards. The concept of integrated system testing itself was debated at length. After much debate, the proposed document allows for the development of a specific NFPA-approved plan for ongoing integrated testing.

Organizations and universities need to correctly identify, design, install, and manage all elements of an emergency communication system (ECS) as part of an overall emergency management program (EMP). An approach includes developing a strategy for the development of an ECS through a structured process that includes risk analysis, master planning, design and installation, and training. If a university receives federal funding, it is required to report crime statistics annually to identify events that have occurred on its campus. The Clery Act amendments enacted in July 2010, a result of the Virginia Tech shooting, were designed to improve emergency response on campuses throughout the United States. NFPA 1600 is a standard designed to assist organizations in the development of an emergency management and business continuity program.


Large-scale building systems integration, such as mass notification systems (MNS) and video image smoke detectors, is aiming to cut costs and decrease energy usage as well as improve communications during emergency situations. MNS are typically designed to convey messages to a population that can be located within a single building, multiple buildings configured as a single campus, or multiple buildings in different locations during emergencies ranging from man-made events and weather-related emergencies to business interruptions and the like. Video image smoke detection functions by capturing images of a space in quick succession, scanning the captured images for obstructions or clusters of particles that may indicate the presence of smoke, and comparing the captured images using an algorithm for previously stored patterns that is indicative of a smoke condition. The systems can be installed in spaces where more traditional spot-type smoke detectors are not always practical, but where early detection of a fire can prove advantageous.
