Puget Sound Emergency Radio Network (PSERN)

The Puget Sound Emergency Radio Network (PSERN) is a voter-approved effort to upgrade and expand the current King County Emergency Radio Communications System (KCERCS). PSERN will primarily serve fire fighters, law enforcement, and other emergency response efforts throughout King County. The PSERN Project (Project) is leading the new emergency radio system development and when complete, a new, nonprofit entity, the PSERN Operator, will operate the system.
