Gaseous Fire Suppression Systems Applied to High Air Flow Environments

By Eric W. Forssell

Information-technology (IT) and telecommunications (telecom) facilities provide critical services that warrant early detection of fires to minimize loss of capability due to a fire. Between the cost of equipment and the potential cost of interrupted business operations, these facilities have a high value. These facilities usually contain a high-density amount of electronics equipment that must be kept cool to prevent thermal failure and to improve longevity of semiconductor devices and magnetic storage devices. Such facilities commonly use high airflow rate cooling in a variety of airflow arrangements.

In an effort to increase the cooling efficiency, a hot aisle/cold aisle configuration is becoming increasingly popular. In this configuration, the cooling air is introduced between alternating rows of equipment racks, referred to as the cold aisle. The air passes through the equipment and is withdrawn from the opposite hot aisle. This configuration limits mixing between supplied cooling air and heated exhaust, which increases cooling efficiency. The use of containment systems to prevent bypass airflow from the cold aisle to the hot aisle further increases cooling efficiency.



Take These Two SFPE Educational Courses This August

As the leading source for continuing professional development training, the Society of Fire Protection Engineers addresses the training needs of fire protection engineers, whether it is instruction for licensure or to update professional skills. SFPE is offering two face-to-face courses at UL labs in Chicago this August 14-18. Enjoy one-on-one interaction with the instructors and have your burning questions answered. Don't delay register today.


Protecting Flammable and Combustible Liquids Course (Aug. 14-16)
This 2-day course instructed by David Nugent, will address a broad range of issues related to safe handling and storage of flammable and combustible liquids. Included in this course is a review of certain large fire losses; strategic planning for safe operations and storage; fundamental risk determinants; navigating and understanding the relevant fire codes, regulations and standards; fire testing and defining the risk, and using passive and active features for specific occupancies. Full course descriptions can be found here.


Introduction to Industrial Fire Protection Engineering (Aug. 17-18)
This two-day course instructed by Kenneth Dungan, P.E., will introduce the fundamentals of industrial occupancies and processes, including the principles of fire protection engineering that affect industrial design and the process of establishing performance objectives and design criteria for industrial fire protection. Full course description can be found here.

Flexible AV Devices


System Sensor’s new L-Series of AV products provide the coverage and versatility to meet virtually any requirement for indoor, wall, or ceiling applications with low current draw, easy installation and easy customization. Common features include functional consistency, field-selectable candela settings, plug-in designs, rotary code switches, universal mounting plates, and small footprint horns, strobes and horn strobes. The mounting plate includes an onboard shorting spring that ensures wiring continuity before devices are installed. With the same family look, the L-Series can be interchanged seamlessly within a building. Unique accessories, like the bezel kits and color lens strobe attachments, make product customization easy.
