2 channel diver radio
The Divex 2 channel diver radio has been designed to provide communications between the diving chamber supervisor and chamber occupants.
Typically used on a twin lock air chamber the chamber radio provides a reliable and excellent audio quality link between chamber and surface. It is manufactured into a 19” half sub-rack for installation into the smallest of spaces and with the same audio quality as the Divex range of HeliCom™ unscramblers, it is one of the best chamber radios the market has to offer.
The chamber radio supports 2 channels which are typically main lock and entry lock. Each lock is installed with a chamber communications box and speaker which connects to the rear of the chamber radio.
The supervisor can choose between using the panel microphone and speaker or headset by means of a push button switch. Communications from the chamber takes priority and is open for the supervisor to hear, the supervisor uses the panel press to talk (PTT) or headset PTT to communicate with the chamber occupants.
Individual volume controls are available for both chamber locks and the supervisor and a selector switch allows the choice of communication with either lock individually or both at the same time.
