Chamber Communication Set

The COMANEX two-channel chamber communication set is a simplex communication set for use with twin lock chambers.
The system consists of a master station fi tted outside the chamber and a speaker/microphone fi tted in each lock. The units are interconnected with two-core cable that passes through the pressure boundary of the chamber.
The master unit is supplied with a fi st microphone fi tted with a press to talk switch. A channel selector switch allows the selection of main lock, entry lock or both. A headset with boom microphone and press to talk switch is available as an option.
Separate send and receive volume controls are fi tted.
A recording outlet allows the conversation with the chamber occupant to be recorded if required.
The master unit is powered from an internal 12 volt rechargeable battery, a separate charger is supplied ;
