How safe is your building? For most people, this question probably evokes ideas about structural integrity, or security systems. However, there’s another crucial aspect most people fail to consider. In emergencies, first responders save lives and protect property, including the building itself. But in order to do so, they need clear and timely radio communication in all areas of the building.
Modern building materials and floorplans (along with dense urban surroundings) often cause issues with poor wireless signal. In these cases, Public Safety DAS (Distributed Antenna System) is an essential life safety solution.
What is Public Safety DAS?
Public safety DAS, also known as ERRCS (Emergency Responder Radio Communications System) provides continuous two-way radio communication, even in areas with poor coverage. DAS utilizes a donor antenna to pick up the radio signal from a repeater site. Then, a bi-directional amplifier (BDA) enhances signal strength throughout the building, aided by a network of antennae placed in problem areas, like stairwells, parking garages, or underground tunnels.
Is Public Safety DAS required by code?
It is, insofar as code mandates adequate radio coverage for emergency responders. International Fire Code section 510 requires that radio coverage inside of all new and existing buildings needs to match the signal strength outside the building. IFC requires 95% radio coverage everywhere in a building, and the NFPA dictates that critical areas (basements, stairwells, etc.) require 99% coverage.
Adequate responder radio coverage must be maintained as a condition of building occupancy, so any building (new or existing) which fails to meet these conditions upon inspection risks losing its occupancy certificate.
IFC 510 was first introduced in 2009, which is fairly recent in fire code terms. As such, AHJs (Authorities Having Jurisdiction) are growing increasingly familiar with the importance of this issue after a brief period of initial lag. Enforcement is likely to pick up over the coming years.
How do I know if my building needs it, and what do I do next?
Tech Electronics can perform a survey to determine whether your building is code compliant, as well as provide a DAS solution to fit your needs if necessary. Our DAS experts have the RF (radio frequency) expertise as well as the familiarity with AHJs and code requirements to ensure your building passes inspections with flying colors. Whether you’re in the early stages of a construction project, or looking to maintain compliance in an existing building, we’ve got you covered.
