Product FAQ's

Ask a Question

  • Does the chamber speaker have a depth rating?

    The 3110 Chamber Speaker is commonly used in Commercial Diving Saturation Systems, that in some cases, are rated to 450 meters. However, the 3110 Chamber Speaker was never tested by a third party that would allow us to provide an official depth rating.

  • How many speakers do I need per chamber?

    In most cases you would have one speaker per chamber; you might also include a Bunk Box (P/N 3112) so your divers can communicate with the surface from their bunk.

  • Can any of these chamber speakers be used with the sound powered phone?

    No. The sound powered phone is a different type of communications system that does not require any type of power source. The sound powered phone is mainly used as an emergency back-up.
