What is DAS?
If the building under construction doesn't pass the Section 510 testing, what is next? A solution to bring your building into compliance is to install a signal booster system that includes a donor antenna on the roof, a bi-directional amplifier ("BDA") in an equipment room and a distributed antenna system ("DAS") that distributes the amplified radio signals throughout the building structure via a series of antennas. A 24-hour battery backup system is required for the BDA. An annunciator that monitors the entire emergency responder radio coverage system ("ERRCS") will be installed near the fire alarm panel at the entrance of the lobby.
Builders are advised to start planning the installation of the ERRCS
in the early stages of construction because this BDA equipment must be
housed in a 2-hour fire rated room and mostly 1/2" cables must be
installed in 2" EMT conduits inside a 2-hour rated riser to the upper
floors and the roof.
Each building varies in size, number of stories, podium structure, below grade parking and building materials. Our experienced engineering group will design a cost-efficient ERRCS system specifically tailored to your building. Many factors tend to block radio communications from emergency responders. You can count on Best Building's professional team to help you meet this challenge and overcome hurdles to prevent delays in obtaining the certificate of occupancy.
