Product overview
The Sonetics SON200 Series Digital Intercoms allow you to connect up to four radios for simulcast interoperability between multiple crews, departments, contractors or jurisdictions, to improve operational efficiency and worker safety. Connect up to 10 wireless Base Stations and interface up to four additional devices, including a cell phone.
Four models fit four sizes of install. The SON201 has six headset and wireless Base Station connections, one radio connection and one auxiliary connection. The SON202 has eight, two and two, the SON203 ten, three and three, and the SON204 ten, four and four. Each radio can be independently selected for listen-only or transmit, and Priority Radio Select overrides all other inputs for emergency transmissions.
A weatherproof Remote Head extends the controls. SON201RH through SON204RH duplicate all controls and indicators for remote use, up to 1,000 feet by cable, and are rated IP67 for outdoor use.
Built for the job: a steel case, glove-friendly touch controls and Advanced Digital Signal Processing noise reduction for clear voice communication, with no clipped words or background noise. It's an easy upgrade from the SON104, with the same electronic and physical connections and full compatibility with existing Sonetics Base Stations and wired headsets.
Add the SON150 Wireless Base Station and APX377 headsets for your team. The SON104 analog intercom is there when four Base Stations and one radio is all the install needs.
