Fire Alarm & Signaling Code

“Prometheus Bound” | Thomas Cole (1847)

NFPA 72 National Fire Alarm and Signaling Code is one of the core National Fire Protection Association titles widely incorporated by reference into public safety legislation.   NFPA 72 competes with titles of “similar” scope — International Fire Code — developed by the International Code Council.  We place air quotes around the word similar because there are gaps and overlaps depending upon whether or not each is adopted partially or whole cloth by the tens of thousands of jurisdictions that need both.

Our contact with NFPA 72 dates back to the early 2000’s when the original University of Michigan advocacy enterprise began challenging the prescriptive requirements for inspection, testing and maintenance (IT&M) in Chapter 14.  There are hundreds of fire alarm shops, and thousands of licensed fire alarm technicians in the education facility industry and the managers of this cadre of experts needed leadership in supporting their lower #TotalCostofOwnership agenda with “code-writing and vote-getting”.   There was no education industry trade association that was even interested, much less effective, in this space so we had to do “code writing and vote getting” ourselves (See ABOUT).

Code writing and vote getting means that you gather data, develop relationships with like minded user-interests, find agreement where you can, then write proposals and defend them at NFPA 72 technical committee meetings for 3 to 6 years.  Prevailing in the Sturm und Drang of code development for 3 to 6 years should be within the means of business units of colleges and universities that have been in existence for 100’s of years.  The real assets under the stewardship of these business units are among the most valuable real assets on earth.

Consider the standard of care for inspection, testing and maintenance.  Our cross-cutting experience in over 100 standards suites allows us to say with some authority that, at best the IT&M tables of NFPA 72 Chapter 14 present easily enforceable criteria for IT&M of fire alarm and signaling systems.  At worst, Chapter 14 is a solid example of market-making by incumbent interests as the US standards system allows.   Many of the IT&M requirements can be modified for a reliability, or risk-informed centered maintenance program but fire and security shops in the education industry are afraid to apply performance standards because of risk exposure.   This condition is made more difficult in large universities that have their own maintenance and enforcement staff.  The technicians see opportunities to reduce IT&M frequencies — thereby saving costs for the academic unit facility managers — the enforcement/compliance/conformity/risk management professionals prohibit the application of performance standards.  They want prescriptive standards for bright line criteria to make their work easier to measure.

While we have historically focused on Chapter 14 we have since expanded our interest into communication technologies within buildings since technicians and public safety personnel depend upon them.  Content in Annex G — Guidelines for Emergency Communication Strategies for Buildings and Campuses — is a solid starting point and reflects of our presence when the guidance first appeared in the 2016 Edition.  We shall start with a review of the most recent transcript of the NFPA Technical Committee on Testing and Maintenance of Fire Alarm and Signaling Systems

NFPA 72 First Draft Meeting (A2024)

Public Emergency Reporting Systems (SIG-PRS) First Draft

Public comment of the First Draft of the 2025 Edition is receivable until May 31, 2023.   As always, we encourage direct participation in the NFPA process by workpoint experts with experience, data and even strong opinions about shortcomings and waste in this discipline.  You may key in your proposals on the NFPA public input facility linked below:

Radio Spectrum for the Internet of Things

Analysis of the FM Radio Spectrum for Secondary Licensing of Low-Power Short-Range Cognitive Internet of Things Devices

Derek T. OtermatIvica KostanicCarlos E. Otero

Electrical and Computer Engineering Department, Florida Institute of Technology

 

Abstract. The analysis presented in this paper indicates that the FM radio spectrum is underutilized in the areas of the continental United States that have a population of 100000 or less. These locations have vacant FM radio spectrum of at least 13 MHz with sufficient spectrum spacing between adjacent FM radio channels. The spectrum spacing provides the required bandwidth for data transmission and provides enough bandwidth to minimize interference introduced by neighboring predicted and unpredicted FM radio stations and other low-power short-range Internet of Thing (IoT) devices. To ensure that low-power short-range IoT devices maintain reliable communications vacant radio spectrum, such as the FM radio spectrum in these areas, will need to be used through cognitive radio.

The “Worldwide Swarthmore Radio Network” is Swarthmore College’s official campus radio station. It broadcasts out of the suburban Philadelphia borough of Swarthmore, Pennsylvania.

Prior to the 1970s, WSRN operated as a carrier signal broadcast to the campus of Swarthmore College only. The station went on the air with 10 watts on October 15, 1972.  Following efforts by the Federal Communications Commission to encourage as many Class D stations as possible to increase power, a campaign was raised by the students of the college, and in the late 1970s, the FCC granted a license for a 110-watt, directional, transmission.

Programming has been eclectic from the 1970s on. Station programming is diverse; music spans “world,” hip hop, blues, folk, rock, pop, R & B, and classical. Talk and comedy programs comprise much of the weekend line-up. Notably “Funk” which ran from fall 2012 to spring 2014 Friday mornings from midnight to 2AM.

In 1986, the main on-air studio was completely refurbished, with a new control panel, turntables, microphones, and wiring installed. 1998 saw the rewiring and modernization of the production studio and the construction of an acoustically isolated sound studio connected to the production studio.

Students have always manned the soundboard, and so, during most summers, the station is dark.  Following the COVID-19 pandemic, the radio station had periods of limited broadcasting. During the 2021-2022 academic year, a significant effort by students, faculty, staff, and community members was successfully carried out to get the station back up to an operational state. As of April 1, 2022, the station has resumed broadcasting.
