Full-Duplex intercom system based on DECT wireless technology that allows bi-directional communication between 9 devices simultaneous, operating on the 1.8 GHz DECT-frequencies, which are license free in most countries, with a range of 150 meters, expandable.
The products in the Peltor DECT-Com II family offer simple and efficient wireless duplex communication with up to 9 active users talking in full conference and additionally up to 40 listeners with possibility to quick "break in" to the conference. In a system with more than 9 users any listening participant can change from listening to speaking. The earliest active speaker will then be "degraded" to a listener in the conference and any other listener can follow, replacing active speakers in the order "first in - first out".
A Peltor DECT-Com II portable unit (DC2811) is a personal radio transmitter/receiver to which a headset should be connected. Any Peltor headset with J11 connector wired according to "Peltor standard" can be connected to a Peltor DECT-Com II portable unit. note that a Peltor DECT-Com II base/portable unit (DC2812) is needed to communicate all information from and to all portable units in a DECT-Com II system.
