Outerloop™ functions as a wireless link to your intercom system. This universal belt pack provides connections for your existing 4-pin or 5-pin intercom headset, routing audio through your mobile device over a Bluetooth wireless connection. Use your cell phone to call into your intercom phone bridge or station phone coupler for a global wireless link. In Phone mode, Outerloop pairs to your mobile phone, notepad, or computer just like any other Bluetooth headset. In Headset mode, Outerloop pairs to a standard Bluetooth headset or another Outerloop, providing a short-range secure wireless point-to-point intercom.
