Product overview
The 110 Radio Interface is the simplest way to add effective communication to a one-person application. At the pump panel or while en route, the operator is able to clearly monitor the radio and transmit information without the interference of engine noise, horn blasts, or sirens. Connected to Firecom headsets, it provides vital hearing protection.
The 110 combines a single mobile radio interface port with a single headset or base station connection, on 12V nominal power. It interfaces directly with a mobile radio, mounts easily and cleanly below the dashboard, and will not disable the existing speaker or handheld microphone. Separate bias and gain controls are provided.
For a vehicle with two crew members, see the 210 Radio Intercom. For multiple radios, auxiliary devices or a remote head, see the 5000D Series Digital Intercoms. Headsets come from the 50-Series Wired Headsets, and the mobile radio interface cable for your radio is on the Firecom parts and accessories page.
