Advanced RF Technologies Inc. (ADRF) announced two new remote units (RU) for its flagship ADXV Series DAS, certified to UL 2524, the standard for in-building two-way emergency radio communication enhancement systems (ERCES).

The ADXV-R-25VU-U2 offers dual-band support for VHF/UHF frequency bands and includes space for either one multiplexer or two band-pass filters within the unit. This design eliminates the need for third-party enclosures, streamlining installation and reducing total cost of ownership. The ADXV-R-3378P-U2 offers dual-band support for PS 700/800 bands and allows users to disable unused bands to minimize unwanted noise. ADRF is also introducing the enhanced point of interface card, ADXV-H-POIL-78P-U2, designed to support the new 700/800 MHz remote units.

The UL 2524 establishes the most stringent standards to ensure reliable communication for emergency responders within and around commercial buildings. It applies to various equipment, including repeaters, transmitters, receivers, signal boosters, remote annunciators, operational consoles, power supply, and battery charging system components. These products are designed for use in compliance with key Model Building and Installation Codes, such as NFPA 1/72/1221/1225, the International Fire Code (IFC) 2015/2018/2021, and FirstNet.

“We are thrilled to round out our UL 2524 public safety offerings with these new remote units for our flagship ADXV Series DAS,” said Sun Kim, director of engineering at ADRF. “As a public safety communications leader for over a quarter century, we are dedicated to providing the most effective solutions to ensure first responders maintain seamless connectivity throughout every area of a building, safeguarding tenants and occupants during emergencies.”
