Transcript: Do You Need Public Safety DAS?

Hi, I’m Clay Kobernick. Imagine you’re a firefighter in a burning building. You discover two people trapped in the stairwell, unconscious. You radio your crew to ask for help carrying them to safety. Unfortunately, there’s no signal coverage in the stairwell, and your message can’t get through. With no way to communicate with your crew or command, your job just became significantly more difficult and dangerous.

When lives hang in the balance, first responders should not be hampered by poor signal coverage. Voice communications, location information and video streaming are vital tools in an emergency. Unfortunately, many buildings have coverage holes, such as elevators, garages, tunnels and stairwells, where wireless communications may be impeded.

To achieve sufficient coverage, buildings must have a public safety distributed antenna system installed. In some U.S. cities, this is a requirement for obtaining an occupancy permit.

The most widely accepted standards for public safety DAS are set by the National Fire Alarm and Signaling Code (NFPA 72) and the International Fire Code. However, the specific coverage requirements vary by location and are not always enforced. Building owners should not aim for minimum compliance, but rather to provide a safe environment for everyone in and around your building.

A reliable public safety communications system meets all of the following requirements:

  • It’s on a different spectrum than your commercial wireless, and is strictly for the use of first responders.
  • Its signal covers the entire building. This includes at least 99% coverage of critical areas such as fire pump rooms, exit stairs, exit passageways and elevator lobbies.
  • It has a backup power source such as a 12-hour battery that keeps the system operational if the building’s power is out.
  • And it has a monitoring system that alerts you to system malfunctions and low power.

By working with a qualified integrator to install a public safety communications system in your building, you can help first responders receive crucial support in the most difficult circumstances.

Key Considerations – In Building Public Safety Systems

Public Safety Fire Communications - Safer Buildings Coalition

Public Safety Fire Communications – Safer Buildings Coalition

What is it?

A Public Safety Communications System is a wireless communications system used by first-responder and emergency services personnel such as police, fire, emergency medical, homeland security, and disaster response agencies to prevent or respond to incidents or situations that pose a threat to people or property.

An In-Building Public Safety Communication Booster System ensures that radio signals can penetrate all areas of buildings, including areas that are especially difficult for RF to penetrate such as stairwells, elevators, basements, and thick-walled or shielded areas.

Key Considerations for Building Owners, Enterprise and related Construction Trades

Know your local Building and Fire Codes and Local Ordinances

These requirements are mandated by the International Code Council Fire Code (IFC) Section 510 as well as the NFPA 72 and NFPA 1221. Local jurisdictions vary. Some adopt these model codes as written, some modify these model codes, and some areas have not yet adopted. Be sure to understand the local code requirements and permitting process during the design and budgeting phase of your project.

Risk of Non-Compliance

For new construction or remodeling, failure to meet code could mean that a Certificate of Occupancy will not be issued. For existing buildings there is the risk of code violations that must be corrected.

Engage the Code Officials and Building and Inspections Departments Early

Build the appropriate timelines into your project plan. Ideally the required infrastructure such as pathways and conduits should be planned and installed before the walls and ceilings are closed up. Waiting until too late can significantly drive up costs.

Costs

The cost of an In-Building Public Safety Communication Booster System is born by the building owner nearly 100% of the time. The rare exception is for public mega-venues where third party operators may deploy a public safety system in conjunction with a cellular repeater system.

Engage Professional Assistance

Work with experienced professional services and Integrators who have done recent In-Building Public Safety Communication Booster System work, preferably with references in the target jurisdiction.

How About Cellular Service?

Today, so many calls originating within a building are made from mobile phones and not land lines. This includes calls to 911. This is particularly critical in common areas, stairways, parking garages, and basement areas. If cellular service is poor in any of these areas the 911 call may never be made. In campus environments like Education, Healthcare, or Corporate campuses, text-alert systems are common for crises and emergency management. Without adequate cellular coverage these outbound contacts fail. Cellular repeater systems use the same technology and supply ecosystem as In-Building Public Safety Communication Booster Systems. In most cases there can be significant cost savings realized by designing and installing these systems at the same time, potentially sharing common infrastructure such as pathways (penetrations, conduits, raceways), power, space, cooling, cabling, antennae, and even active components.

Key Considerations for Building and Fire Code Officials (sometimes called AHJs, or Authority Having Jurisdiction)

Publish your Local Standards and Permitting Procedures

Unlike sprinkler system or electrical codes, In-Building Public Safety Communication Booster Systems are relatively new requirements and much of the market and industry is navigating a steep learning curve. Make sure your requriements are clearly documented, and that pre-construction permitting procedures and documentation requirements are clearly defined and published. Otherwise, expect to field many phone calls to answer the same questions over and over again.

Specify Your Testing / Inspection Procedures and Documentation Requirements

Some agencies are staffed such that on-site inspections are feasible. Some jurisdictions prefer that the owner engage a qualified third-party professional services company to test and document system performance and compliance to code. Make your requirements known in advance.

Balance Objectives

Make sure the requirements in your jurisdiction meet the need of ensuring critical communications without imposing unnecessary additional costs. The NFPA and ICC routinely engage experts from both the Fire Professional community as well as from the technical industry to continually adapt model codes that accomplish this balance.

Participate in Industry Forums that Provide Training and Public Information

Groups like the Safer Buildings Coalition provide training, seminars, and other opportunities and context for engaging the In-Building Public Safety Communication Booster System supply ecosystem, and also to get the latest information about new and proposed fire codes as well as new FCC regulations and other requirements.

Member Feature | RF Connect Delivers Major Dallas Highway Wireless Radio System Coverage for First Responders

 rfconnectlogoThis week’s member feature highlights Safer Buildings Coalition Member, RF Connect. As a recognized leader in the design, deployment, and support of high performance wireless and mobile solutions at high-capacity public and private venues around the nation, RF Connect is a significant contributor to the mission and goals of the SBC.

The Challenge:

RF Connect’s latest project includes over 7 miles of highway in Dallas County, Texas. This piece of highway is included in the LBJ Express project were it has been identified as below grade in a cantilevered tunnel effect, making public safety radio transmissions impossible. Because of the lack of radio signal in those areas, first responders were hindered from making or receiving calls. Law enforcement, fire, ambulance and other public safety radios for first responders were silenced, endangering the lives and safety of the public and the first responders.

The Solution:

RF Connect constructed a first responder public safety wireless radio coverage system for the 7 miles of cantilevered below grade roadway. RF Connect designed the system on the VHF, UHF, 700, and 800 MHz public safety radio spectrum bands, giving first responders open communication channels.  Due to the complete lack of public safety signals below grade, and the critical nature of those communications for the public and first responders, RF Connect designed the system with full redundancy so no single failure would cause an outage. A full 24 hours of battery back-up was included with the capability to add mobile generators for power outages beyond 24 hours. RF Connect integrated the system with multiple vendors’ equipment and provided a comprehensive alarm monitoring and maintenance program to guarantee the highest quality communications for public safety on all bands.

Despite the delays in construction from Dallas’ record rainfall in the Spring of 2015, the project met its opening date goal and was, in fact, completed ahead of schedule, thanks to the overall collaboration of all parties involved. “Our number one concern is the safety of the public on the roadway and the reliability of the highway system. Due to the lack of signal for first responder radios on the below grade sections of the roadway, we partnered with RF Connect to design, deliver and test a solution for all of the public safety entities that keep the traveling public safe,” explained LBJ Express COO, Jason Sipes.

About the LBJ Express Project:

When the LBJ Freeway opened in 1969, it was designed to hold about 180,000 vehicles per day. In 2008, the Freeway was counting 270,000 vehicles per day with demand expected to exceed 500,000 vehicles per day by 2020.

To accommodate the increased traffic, the 13-mile LBJ Express project called for improvements along Interstate 635 and Interstate 35E, including rebuilt main highway lanes, a continuous frontage road system and 13 miles of new express managed toll lanes. Crucial to the highway improvement project is RF Connect’s construction of the public safety wireless radio coverage system for first responders in below grade areas.
