110 Radio Interface
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.

210 Radio Intercom
The 210 intercom system is specifically designed for vehicles with two crew members. You’ll get the same advanced features and the proven performance of our larger systems, but won’t pay extra for options you don’t need. The 210 intercom system enhances communication and protects your crew from hearing loss. It’s perfect for volunteer departments, brush trucks, command vehicles, tankers, and more.

Modular Jack(s) – connects the intercom unit to the headset modules using CA cables.

Radio Interface Jack – 9-pin D-Sub connector for a mobile radio interface cable.

Power Connector – connects the intercom unit to the vehicle’s power supply; 2-pin connector.

System Configuration – The 110 and 210 intercoms mount easily and cleanly below the dashboard. Headset modules can be located in any number of positions to provide easy access for headset plug-in. Both systems allow for an external headset module, and headsets can be interfaced with a handheld radio if desired.
