To ensure all occupants of buildings remain safe, it is critical to have a reliable system in place that allows first responders to communicate without interruption in service. Radio communication for first responders is essential during an emergency, however, building materials can frequently block wireless signals.
Since 2009 the International Fire Code (IFC) has required all new buildings to have approved radio coverage. In Seattle and Oregon state, the requirement is further defined for any building over 50,000 square feet (about half the area of a Manhattan city block).
But what exactly is Public Safety DAS and what are the requirements? Continue reading to learn more.

Public Safety DAS is a series of antennas that provide enhanced two-way radio service that evenly distributes the amplified signals. This system ensures that first responders can seamlessly communicate within the building and with those outside without interruption in service.
Since this communication has its own radio antennae system, it is not impacted if telephone lines or cellular towers fail, which can happen during natural disasters.
It is mandated that a building provides adequate coverage as outlined by the IFC and NFPA regulations set in place by the local municipality. Emergency Responder Radio coverage was first added to IFC in 2009 as section 510. 510.1 states that the radio signal strength on the inside of the building needs to match the signal strength on the outside.
The IFC dictates that 95% coverage is needed everywhere, and NFPA dictates that 99% of coverage is required in critical areas such as equipment rooms, basements, and stairwells. These regulations must be met to facilitate the wireless communication needs of first responders.
The National Fire Protection Association (NFPA) Standard 1225 and section 510 of the IFC have also outlined annual testing requirements for any building with Public Safety DAS installed to ensure dependable emergency communications. There is a 5-year test that is required for any building over 6 years old.
This means every existing and new building must be maintained to meet the minimum reliability level for first responder communication as a condition of occupancy. If a building fails to meet these regulations, it could lose its certificate of occupancy.
To comply with the codes and ordinances, many states are making it mandatory for a Public Safety DAS expert to test all new and existing schools to ensure they pass all the code requirements.
At PSI, our DAS inspection experts can provide annual testing to ensure your systems provide dependable emergency communication and are compliant with NFPA Standard 1221. The PSI testing certification includes:
