2 Channel Chamber Radio

2 Channel Chamber Radio

The chamber radio has been designed to provide communications between the chamber supervisor and the 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 subrack 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 & Entry Lock. Each lock is installed with a chamber comms box and speaker which connects to the rear of the chamber radio.

The supervisor can choose between using the panel microphone & 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.

3 Channel Diver Radio

3 Channel Diver Radio

The diver radio is battery operated and houses two batteries and a three stage smart battery charger within the case. The in built batteries will provide in excess of 10 hours constant communication between the supervisor and three divers and the three stage smart charger will charge the batteries from a fully discharged state in approximately four hours. A battery monitor provides a visual indication of the battery status at all times when the power switch is in the on position.

The diver radio supports 3 channels which are Diver 1, Diver 2 & Diver 3. Each Diver channel has industry standard banana sockets for connection of the diver’s umbilical and both 2 wire and 4 wire comms can be used. When using two wire comms the umbilical is plugged into the red (microphone) socket only and when using 4 wire comms the umbilical is plugged into both the red (microphone) sockets and the black (headphones) sockets.

Diver Round robin is also available which allows diver to diver communications, this is selected by switching the Diver R-R switch to the on position.

The supervisor can choose between using the hand held microphone & panel speaker or switch to headset only. When the speaker switch is in the on position comms to the speaker can be heard and the supervisor will use the hand held mic PTT to talk to the divers. When the speaker switch is in the off position a headset with an in line PTT switch can be used. A panel mic is also available for use if the hand held mic or headset are not available. The volume to the panel speaker or supervisor headset is controlled by the supervisor volume pot.

The supervisor can choose to communicate with each diver individually or to all at the same time. The diver select switch is used to select which diver the supervisor is communicating with, either diver 1, diver 2, diver 3 or all can be chosen.
