Public Safety DAS

TurnKey RadioBoost Public Safety Distributed Antenna System

Public Safey DAS

Essential in-building wireless communications save lives.  In-building wireless communications for public safety emergency responders. Spot On’s turn-key solutions handles everything from work with the AHJ, to design, installation and on-going certification of your system. 

Emergency Responder Radio Coverage

Compliant with All National & Local Coverage Mandates


Both the National Fire Protection Association (NFPA) and International Fire Code (IFC) mandate coverage for emergency responders.  If your building is not able to meet the IFC mandate of 95% coverage in all areas and the NFPA mandate for 99% of radio coverage in areas of vital importance you may be risking your buildings certificate of occupancy.  IFC and NFPA mandate minimum coverage requirements at the national level, however locate mandates (dictated by the local Authority Having Jurisdiction (AHJ), usually the fire marshall,) may be more complex.

 

 

A Turn-Key Public Safety DAS Solution

Why Public Safety DAS?

Building construction material block both radio and cellular frequencies turning residential and commercial buildings into communications dead-zones.  Lack of radio communications for emergency responders puts responders, residents, staff and the public at serious risk.  A Public Safety DAS ensures that all local and national mandates for radio coverage are met so that in the event of an emergency, first responders have the 2-way radio communications they need to stay in contact.  

Coverage Requirements

Coverage requirements are mandated at both the local and national level.  Local coverage mandates vary depending on the Authority Having Jurisdiction (AHJ) – usually the Fire Marshal.  Minimum standards for coverage at the national level are dictated by the National Fire Protection Association (NFPA mandates 99% coverage in areas of vital importance and 90% coverage in general areas) and the International Fire Code (IFA mandates 95% coverage in all areas).  Radio frequencies are those used by local public safety personnel (UHF/UHF 700 and 800 mhz bands).  

In areas where NFPA and IFA require coverage, a minimum signal strength of -95 DB is need for any frequency.

Failure to meet coverage requirements can delay obtaining a certificate of occupancy or result in fines.

A Turn-Key Solution
  • Spot On Networks solution for Public Safety DAS is turn-key.  We handle every aspect of the system from determining coverage requirements with the AHJ to design, installation and certification of the system.  Our GROL engineers are in-house employees of Spot On Networks.  Because building owners are typically under a deadline to get a Certificate of Occupancy, we believe that having the staff in-house required to test, design, install and work with the AHJ, makes the process smoother and more efficient. 
GROL Engineers

Public Safety radio coverage requires expertise and Spot On Networks is proud to employ in-house GROL (General Radio Operators License) engineers to ensure that each Public Safety product meets the coverage requirements mandated at both the local and national levels.  Our GROL engineers are dedicated to managing each project from initial requirements gathering with the Authority Having Jurisdiction, through the design, equipment procurement and installation phases to the final certification of your system.

 

Building owners should be aware that most companies dealing with Emergency Responder Radio Coverage (ERRC) specialize in one aspect of the system and outsource the rest.  It is required that GROL engineers test, design and certify a Public Safety Radio Coverage system.  At Spot On Networks we are hands on for each step of the process.  Our investment in in-house GROL engineers ensures that your Public Safety Radio project will be handled as efficiently as possible.

Public Safety DAS Process

The first steps to installing a Public Safety DAS system are determining local coverage requirements and conducting a site survey of the property.  This site survey needs to be done by an engineer with a GROL (General Radio Operators License).   Unlike a cellular site survey – the GROL is REQUIRED to determine coverage.  Once coverage is determined, the network is designed and the BDA (bi-directional amplifier) and antennas are ordered.  Lead time for Public Safety DAS equipment is a minimum of 16 weeks and can be longer if custom equipment is required.  Once equipment is built, the network is installed and Spot On GROL works directly with the AHJ to ensure compliance and certification of the system.  A re-certification is done annually.

Components of Public Safety DAS

A Public Safety Distributed Antenna System is comprised of a bidirectional amplifier and antennas.  All public safety network equipment is housed in NEMA (National Electrical Manufacturer Association) enclosures in accordance with NFPA and IFC mandates so that the equipment is  protected from water and weather.  System monitoring alarms provide real-time monitoring of the system to show readiness or communicate equipment, power or battery failure.  Battery backup is required .  During an emergency, power will usually fail leaving the system vulnerable.  A public safety DAS needs to function for 24 hours on a backup battery.
