Public Safety DAS; NFPA 72 and Best Practices


Tagged Under : , , , , , , , , ,

The enforcement of  Public Safety Indoor Radio Coverage is popping up all over the nation and as a result many of our new clients are asking for help understanding the  regulations and what is involved with correcting problems should their building fail.  I put together a document, which I give to just about everyone that calls.  It provides a listing of all the pertinent sections of NFPA 72 – 2013.      https://docs.google.com/document/d/1Gxr5DXHTWpGV6Bhe0E_Jooc-NGr1FkjM06L0REJujhc/edit?usp=sharing

I can’t copy the NFPA but you can access a Free online copy at http://www.nfpa.org/codes-and-standards/free-access

The requirements and the type of Public Safety Radio System is a variable from jurisdiction to jurisdiction.  Even the frequency bands used within a jurisdiction are all over the map and, of course,  the odds are, it’s going to be different in the neighboring jurisdiction.   Digital P25 technology may improve inter-operable communications between agencies, but it does very little to change the wide range of frequencies the building owner must address in his system design.  The national Broadband Network (FirstNet) is also looming around the corner and will naturally be added to local requirements as it becomes available.   If you don’t have a 700/800MHz digital signal booster, you probably are going to fork out some more money in the future.

System flexibility and the ability of the cable path to accommodate changes are paramount to long term savings.   Best Practices include:

  • Utilize a professional to get things started.
  • Have good specifications to ensure you are getting  products and services that meet regulations and local requirements.
  • Ensure quality and code compliance through 3rd Party inspection and testing.
  • Plan long term resources and life cycle costs.

RFSignalman provides several template specifications to assist our clients with these objectives and our web-site is a good source of information.  If you don’t find it…….ask.

Quality – Public Safety Radio – Is it really important?

“Quality doesn’t just happen.”

When it breaks – it’s cheaper to get a new one.  This is true for so many things these days from kitchen gadgets to printers and cell phones.  With products becoming cheaper and cheaper to manufacture, the quality standard seems to be based on the time it takes something to fail.  That being said…..wouldn’t you think the quality objective of something that is not supposed to fail…..say something your life depended on……should be very high.

Quality and survivability are extremely important to the First Responder.  When your life depends on it, there is no place for cutting corners or using unreliable parts or equipment.  That’s why Public Safety Radio systems are designed to be 99.9999% reliable (approximately 52 minutes of outage per year).  The Radio is one of the most important tools used by First Responders and is crucial for support and coordinating on-site efforts.  A delay in communications can have serious impacts to the outcome of an emergency situation.  The following link provides an excellent overview of fire communications and how indoor coverage fits into the picture. http://iafc.org/files/commComm_GuideRadioCommForFireServ.pdf

The Building Owner is now responsible for Public Safety Radio coverage inside buildings.  Although it may seem financially tempting to skimp on quality when  first hit with a new requirement –  it never pays in the long run.  As a preventive measure, the FCC has just issued new rules for commercial, industrial and Part 90 users of Booster Systems that go into effect March 2014.  These rules are accompanied with stiff fines starting at $100K. and a requirement to register equipment. http://wireless.fcc.gov/signal-boosters/index.html .  High Quality Systems, Monitoring and Testing are the Best Practices to ensure compliance with CA Fire Code Section 510  and NFPA 72 requirements as well as keep the FCC off your back.  https://law.resource.org/pub/us/code/bsc.ca.gov/gov.ca.bsc.2013.09.pdf
