Two Channel Chamber Comms Set

Chamber Communications and Chamber Speaker


The SAT Systems two channel chamber communications set is a simplex communications set for use with twinlock chambers.

The system consists of a master station fitted outside the chamber and a speaker/microphone fitted 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 fist microphone fitted with a press to talk switch. A channel selector switch allows the selection of main lock, entry lock or both. The master unit listens to the chamber until the press to talk switch is pressed. A headset with boom microphone and press to talk switch is available as an option.

Separate send and receive volume controls are fitted, neither volume control can be turned totally “off”. 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; the charger can be left permanently connected to the battery. The battery then acts as a reserve power supply in the event of mains failure. Battery autonomy is about 24 hours depending on talk time and background noise.
