ADRF Releases Emergency Power Off (EPO) Switch for its Public Safety Repeaters

EPO is a Burgeoning Requirement for ERCES Installation in US Counties

BURBANK, Calif., August 14, 2023 -- Advanced RF Technologies, Inc. (ADRF), the largest pure-play distributed antenna system (DAS) and repeater provider, today announced the release of its new Emergency Power Off (EPO) Switch for public safety repeaters. The user-friendly PSR EPO Switch enables manual cutting and restoration of AC power and DC battery backup to the repeater, whereas most emergency responder communication enhancement systems (ERCES) can only be shut down through a graphical user interference which takes time to access.

The EPO Switch, available as either PSR-EPO-PKG-U or PSR-EPO-PKG-X, helps system integrators and building owners meet EPO requirements for ERCES in select United States counties such as San Francisco and Santa Clara as well as Washington D.C. The PSR-EPO-PKG-U consists of the PSR-EPO-ENC (enclosure) and the PSR-EPO, while the PSR-EPO-PKG-X includes the PSR-EPO and the PSR-EPO-CBL-X (cable set).

"The EPO Switch reinforces our long-time promise to provide customers with public safety solutions that meet the needs of every deployment regardless of jurisdiction," said Sun Kim, Director of Product Engineering at ADRF. "As the public safety communication industry continues to grow in size and complexity, it’s important to be vigilant in developing useful add-ons to our flagship products.”

Both PSR-EPO-PKG-U and PSR-EPO-PKG-X are available for purchase today. For more information about these products and their features, visit or contact
