Property Responsibility for Maintaining a DAS
Just like fire alarm systems or sprinkler systems, public safety Distributed Antenna Systems (DAS) must be maintained in working order and periodically inspected per the International Fire Code, Section 510.6.1: The owner of the building or owner’s authorized agent shall have the emergency responder radio coverage system be inspected and tested annually or where structural changes occur including additions or remodels that could materially change the original field performance tests.
Buildings are responsible for incorporating changes to the broadcast system (e.g. PSERN). Per the International Fire Code, Section 510.6.2: The building owner shall modify or expand the emergency responder radio coverage system at his or her expense in the event frequency changes are required by the FCC or other radio licensing authority, or additional frequencies are made available by the FCC or other radio licensing authority. Prior approval of a public safety radio coverage system on previous frequencies does not exempt this section.
Contract a DAS Vendor
To re-tune and recommission public safety DAS, properties must contract a DAS Vendor by September 1, 2021 to:
- Assess your current DAS equipment and configuration
- Perform updates to meet the PSERN radio system requirements
- Provide instructions and demonstrate to your Building Engineer how to temporarily disable your DAS in the event it is causing interference with the PSERN system
Recommended Criteria for Selecting DAS Vendors
The following are suggested criteria for a property to consider when selecting a DAS Vendor to service a public safety DAS:
- Valid Federal Communications Commission (FCC) issued general radio operator’s license (GROL) held by the vendor.
- Certification of training by manufacturer of DAS equipment installed in the building.
- Other DAS training from trade organizations or other DAS equipment manufacturers.
- Records of performance describing execution of DAS installation, scheduling milestones, and quoted pricing.
- Records of experience with similar buildings and scopes of work, especially servicing and recertifying DAS.
- Customer references – consider similar size of building, type of building, geographic location.
- Demonstrated understanding of local interpretation of relevant fire code.
- WA licensed professional engineer on staff.
