DAS Stakeholder Roles and Responsibilities

There are five main stakeholders in the PSERN Project DAS Transition: Radio Operators (Current/Future), Authorities Holding Jurisdiction (AHJs), Property Owners/Building Managers, DAS Vendors, and Radio End-Users. The following is a high-level description of each stakeholder’s role and responsibilities, in this transition. If you have any questions, please contact DAS-PSERN@kingcounty.gov.

Radio Operators

The current King County Emergency Radio Communications (KCERCs) system is provided by four separate radio operators, but when the PSERN Project is completed, the future public safety radio system will be provided by one new PSERN Operator. More information can be found here.

Fire Marshals/Authorities Holding Jurisdiction (AHJs)

The Authority Holding Jurisdiction (AHJ) will in most cases be the local Fire Marshal. The role of the AHJ is to uphold the  adopted fire code. WA State Fire Code, Section 510.6.2 requires buildings in their jurisdiction complete the DAS Transition properly. The AHJs will be working closely with the PSERN Project to coordinate communications with buildings. Property Owners/Building Managers can direct compliance questions to their local Fire Marshal. The PSERN Project is currently working on creating a contact list of AHJs in King County.

Property Owners/Building Managers

Property Owners, and their building management, whose buildings in King County host public safety Distributed Antenna Systems (DAS), are responsible for maintaining their DAS. Just like a fire alarm system or sprinkler system, DAS must be maintained in working order and periodically inspected. Per the WA State Fire Code, Section 510.6.2, the Property Owner is required to incorporate changes made to the broadcast system. The broadcast system is the PSERN Project system being built. In early November 2020, the PSERN Project mailed a letter to all King County properties with a DAS.

DAS Vendors

Distributed Antenna System (DAS) Vendors need to be contracted by the Property Owner/Building Management. The role of the DAS Vendor is to assess the buildings current DAS by September 1, 2021, reconfigure the DAS to meet performance requirements for the new broadcast system, and validate performance with the Radio Operator and the AHJ.

Radio End-Users (Emergency Personnel & AHJs)

The Radio End-Users are primarily fire fighters, law enforcement, and other emergency personnel who may need to utilize DAS within a property as part of an emergency response. AHJs will require annual testing of DAS.
