COURTS RADIO SPECS Rev.docx

This is a specification document for a court security radio system upgrade for the State of Maine. The project involves replacing an existing radio system with a new 800 MHz digital and analog radio system across multiple judicial facilities. The procurement includes 100 portable NX-420K3 NEXEDGE radios with associated accessories and chargers, 3 mobile NX-900 radios for installation at a vendor-determined location, and 2 NXR-900K repeaters for fixed installation at Cumberland County Courthouse and Penobscot Judicial Center. Base radio installations are required at four locations: Cumberland County Courthouse, Penobscot Judicial Center, Lewiston District Court, and Knox County Courthouse. Each base installation includes an NX-900 mobile radio unit, power supply, antenna hood, and collinear base antenna. The specification document lists all necessary supporting equipment including duplexers, amplifiers, antennas, cabling, connectors, and racks for the repeater systems, with all labor for installation and setup included.

The specification requires bidders to utilize existing base antenna infrastructure, with cables and antenna mounts not to be included in the quote. The project encompasses approximately 300 feet of foam hardline cabling and associated RF equipment for the repeater systems. All quoted items must comply with the listed specifications including frequency ranges (806-870 MHz and 806-896 MHz), power ratings (15W mobile, 75W output amplifiers, 250W continuous duty duplexers), and channel configurations (512 channels, 128 zones for mobile units). The specification indicates this is a complete system replacement requiring coordination across multiple court facilities and vendor-provided installation labor for base radios, repeaters, and mobile units.
