Getting DAS and any other form of supplementary In Building Wireless (IBW) solutions installed right at the aperture of the construction phase is, in one word, smart. Last week we covered this topic and discussed why implementing DAS at the architectural stage is not only a smart move, but a crucial one in the day and age of 5G and IoT. Similarly, there are also several requirements of the Public Safety DAS, which are mandatory elements to adapt during construction phase.
Firstly, it is important to note that 70% of continuity of 911 calls take place over the cellular network and 64% of those calls made to 911 are indoors (according to wia.org). That number alone explains why a flawless Public Safety DAS can be life-saving, to say the least!
Whether you’re a general contractor, a building owner, a property manager, or a construction project manager, you’re most likely aware of several jurisdictions that now have the NFP or IFC compliant Public Safety coverage as a mandatory prerequisite to an occupancy permit. But do you know all the minutiae of how the coverage is tested? Are you fully aware of how the Public Safety coverage in your building can be improvized?
Know the kind of Public Safety Coverage required by your local jurisdiction
It goes without saying that all first responders are there to save lives - in one form or another - and must be able to make and maintain the communications. Not only for the obvious parts of the building, but all throughout the property including staircases, basements, terraces, back-rooms, cool-rooms, storage areas, elevators, and all forms of tricky spaces and corners, as well as thick-walled areas.
Note that this is NOT a nicety but a requirement instead. Almost every county in the country has legislated local codes and statutes to make Public Safety IBW coverage mandatory for the first responders. Not only the mere installation, but the quality, reliability, and performance standards of the coverage are also a condition, and it is a full responsibility of the building owners - residential or commercial - to install, test, and monitor the IBW system to the required standards by the code.
Some of the requirements were covered in our past blog which can be found here. Below is the list of three requirements each from NFPA and IFC as a synopsis.
