The tools and equipment necessary to install and test a fire alarm system have changed over the years, and until a fire official asks to perform a particular test, many contractors may be unaware that they need a new meter or specialized piece of equipment.
As network technology becomes increasingly important to operate security systems, and affordably priced Internet protocol (IP) cameras and video management systems (VMS) are used more often, system designers and installers, such as electrical contractors, are realizing the need and efficiency of usi
From talking to electrical contractors lately, I know it’s still tough to get profitable work in the current economy. However, I also find most of the contractors who have prepared well for such a poor economic situation are maintaining a substantial workload.
In May of last year, the Department of Fire Protection Engineering at the University of Maryland conducted a study to demonstrate the relative performance of smoke detectors and sprinklers in one- and two-family dwellings and apartments, commercial residential (e.g., hotels), and institutional occup
As an electrical contractor, you understand the need and use of power for all electrical appliances, but do you understand the specific power requirements, both primary and secondary, for all of the fire alarm systems outlined in NFPA 72 2010, the National Fire Alarm and Signaling Code?
The 2009 Life Safety Code underwent significant changes from past versions, especially in Section 9.6 and the requirements regarding voice messages. The International Building Code (IBC) and NFPA 101, the Life Safety Code (LSC), differ in how they handle the delivery of emergency messages.
The codes that affect your day-to-day business change every three years. The frequency of changes makes it difficult to stay abreast of the countless revisions that occur each code cycle. Coupled with rapid changes in technology, staying current becomes challenging.
Most professional contractors are comfortable advising what building owners should include in an electrical design project; the contractors’ expertise is based on their years of experience and knowledge of the National Electrical Code.
This year, the International Association of Fire Chiefs (IAFC) submitted 41 proposals for NFPA 72, the National Fire Alarm and Signaling Code, in an effort to reduce false alarms caused by fire alarm systems. Is there really a problem? How do we, as an industry, reduce unwanted alarms?
Conducting a fire alarm system acceptance test in front of a fire official can prove daunting, even when the system passes muster. But doing any form of fire alarm system testing without having the proper tools is downright foolish.
The very nature of design/build projects requires you to participate in the design process. You may even feel comfortable with assisting in this process. However, these types of projects come with increased responsibility. With most design/build projects, the owner will ask you for your opinion.
In previous columns, we discussed the two major changes to NFPA 72 2010, the new emergency communications systems chapter and the new circuits and pathways chapter. There are quite a few other changes that are worth discussing.
Readers of the National Fire Protection Association’s (NFPA) 72 2010, the National Fire Alarm and Signaling Code, will find many changes including three new chapters. One of the new chapters is dedicated to circuits and pathways.
There have been extensive changes to the 2010 edition of NFPA 72, the National Fire Alarm and Signaling Code. One of the more significant changes was the addition of the circuits and pathways chapter, Chapter 12. Twenty years ago, all we had to describe fire alarm circuits was Class A and B.
