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.

The main features are:

  • Portable unit for use in a DECT-Com II conference with up to 9 simultaneous speakers in full duplex.
  • The DECT-Com II conference can also have an additional number of listeners, all with possibility to enter as speakers in the conference, at any time.
  • Headsets with different types of microphones can be used.
  • Full duplex communication, but with "VOX", for preventing from transmitting background noise to the conference.
  • An "all call" function makes it possible to communicate common messages (simplex) to all users in all groups, at the same time.
  • The portable unit is normally power supplied with rechargeable battery pack. (Can also be used fixed installed, power supplied in a special holder with AC adapter.)

This product includes the battery, but does not include the power supply or the holder needed to charge.
