What is a Full Duplex Wireless Intercom?

Earmark is a leading manufacturer of wireless communication systems for use in noisy environments. For many years, the firefighting community has been asking for a wireless interface to their traditional hard-wired intercom systems. Earmark has developed a technology that allows pump panel and aerial operations to be performed while maintaining full duplex wireless connectivity to the fire truck intercom as well as the fire truck radio.

The Earmark system, called wLINK®, consists of a base station which is mounted in the cab of the fire truck and is hardwired to the fire truck intercom system which is, in turn, hard wired to the fire truck radio and a portable unit that is connected to a headphone. The portable unit fits easily in the radio pocket of a turnout coat. The truck battery powers the base station while the portable unit is battery powered with over 12 hours of available usage. Upon reaching the scene of an incident, the pump panel operator no longer has to be tethered to the truck and can move within 300 feet of the truck while maintaining connectivity to the intercom and, by using a large, easily accessible push to talk button, the truck radio. The system provides excellent hearing protection and has the durability and weather resistance required by the firefighter.

Why upgrade to Wireless Radio Equipment for Firefighters?

Firefighter safety is of utmost importance and the wLINK® system greatly enhances that by eliminating the long cord connected to the pump panel. The pump panel operator no longer has to unplug from the truck to perform other duties such as hydrant work, there is no cord to break or get entangled in other equipment. The jack on the panel no longer has to be open where water damage can short out the fire truck radio, which causes it to constantly transmit. Fireground communications are improved since the mobility of the firefighter is infinitely better and they can do their job where they need to rather than where their equipment allows it.

Can I continue using my current Radio Headset?

Yes. You can also browse radio headsets by Earmark.

The wLINK® wireless intercom system is the latest Earmark innovation in the fire truck accessories and equipment market. Designed specifically for the need to improve firefighter safety and efficiency, it was designed in conjunction with fire departments to make sure the functionality meets their needs.
