At this point in the project a distributed antenna system (DAS) incorporating bi-directional amplifiers (BDAs) to boost, enhance, and increase the coverage must be designed and installed. The code has specific requirements for certification to design and install these systems as well as requirements for fire alarm monitoring of the system components. This solution cannot be met by one entity. Drawings must be submitted for permit and fire code official approval with a PE seal. JDRM has aligned with a number of strategic partners to form a design/build team to implement and execute a code compliant system and get competitive pricing for your project.
This question comes up often and is extremely important. There are several options that JDRM FRR Testing team suggests:
Unlike other code requirements, emergency communications systems for first responder radio should not be designed up front without testing results. We see a number of specifications requiring a bid for a system without any testing being conducted or test results provided. Though this will get you a price, it is not necessarily an accurate price. There are a number of issues with this approach:
Several reasons besides the code required annual test may occur and require you to re-test.
There is no easy “yes” or “no” answer to this. It depends on the frequencies, your carriers, certain signals are not recommended to be mixed together on the same system — and there are more factors to consider. Please call us, we’ll be happy to guide you through that process.
