Overview

WARNING: DO NOT USE THE AMRON AMCOMMAND ™ II 2 DIVER - AIR CONTROL/ COMMUNICATIONS SYSTEM FOR THE FOLLOWING

  1. Mixed gas commercial diving operations with an oxygen level greater than 40%
  2. Oxygen or oxygen enriched breathing mixtures above 40%

High Pressure Side

  • High air pressure inputs include two color coded (red and blue) SCUBA bottle yokes with six foot air hose whips.
  • Each input has a 0-5000PSIG gauge and shut off valve to monitor and switch from one high pressure air source to the other.
  • The added safety feature of check valves provide protection against back flow of air from a full tank into an empty when switching high pressure air tanks.
  • High pressure air is reduced to low pressure via a Tescom pressure reducing regulator with a pre-regulator in-line 50 micron filter. A 0-400PSIG gauge monitors the output pressure. A relief valve (factory set at 285PSIG) prevents over pressurization.

Low Pressure Side

  • Input check valve permits simple switching to back-up high pressure air in the event of low pressure air failure. Back-up high pressure air supply can simply be turned on. Commercial diver umbilical air connection is an oxygen type fitting, controlled by a quarter turn ball valve which permits unrestricted flow.

Hardwire Communications

  • The 2-Diver hardwire communicator is powered by two internal rechargeable Gel-cell batteries complete with the Amron external charger and noise canceling hand-held push-to-talk microphone. The PTT mic eliminates the transfer of all topside noise to the commercial divers and improves communications quality.
  • System can also be purchased with the 2.4 GHz Wireless Tender Option - provides the tender complete mobility to move around the commercial or search and rescue dive site and still remain in constant contact with commercial divers.
  • Also available: Amron Walk & Talk Module - allows the tender to remotely operate unit from up to 25ft. away.

Pneumo (Depth Monitoring) System

  • The heart of the pneumo system is the high precision 6 inch depth gauge. The gauge dial has a glare free face and is clearly marked for fast, accurate readings.
  • An air low pressure alarm monitors air pressure supplied to the commercial divers and activates an audio alarm alerting the tender of low air pressure conditions. The air pressure switch is preset at 100PSIG and can be manually adjusted to any air pressure between 22.5 and 112PSIG.

Descriptions

The Amron International Amcommand II Two Diver - Air Control/Communications System is a portable, self contained, two diver complete commercial dive system. This air control system provides all of the operations necessary to monitor and control the commercial diving operation. It is a central control point for the supply of breathing air to the commercial divers. This Amron system monitors the commercial divers' depth, provides an audio alarm if the commercial divers' air pressure falls below a preset limit, and provides superior hardwire diver communications for two commercial divers and topside personnel.

Easy set-up with high pressure air sources or low pressure air, which greatly extends search and rescue diving capabilities. To use the Amron Amcommand ™ II with 4500PSIG inlet air supply, simply change the yoke assembly with the Sherwood HAS-300D Din Adapter 300 Bar. The hardwire diver communications system can be both full duplex or simplex. The optional Amron International Model 2829-11 Wireless Tender Kit provides the tender with freedom around the dive site while staying in constant communication with the divers. The case is extremely strong and durable, constructed of pressure fused fiberglass that provides a convenient, compact, rugged and professional system designed for years of reliable operation.

2 or 3 Year Extended Warranties are available for this product. Please refer to the Attachments tab for further information on the program and the Accessories tab to purchase them.

FAQ
 

Product FAQ's

Ask a Question

  • Should I use a GFI when operating my radio off AC power?

    When operating your Amron Diver Communicator on AC, it is critical to use a Ground Fault Circuit Interrupter (GFCI) or isolation transformer for tender and diver safety. Surges and spikes are common on AC lines found on ships, generated locally, or at the end of long extension cable runs and can exceed 1kVolt. Such surges and spikes can cause the fuses, F1 and F2, to blow on the battery charger board and in extreme cases damage the charger circuitry. The battery charger is designed so that such a failure will be isolated and will not cause a safety issue to the tender or divers. It is strongly advised that your Amron Diver Communicator be operated on an AC circuit with a high quality surge arrester or an AC isolation transformer.

  • Can I connect my one diver communicator to my computer so I can record audio?

    Yes, you will need a cable that allows you to connect the communicator to your computer. You will also need audio recording software installed on your computer. On the back of the communicator there is a single RCA Phono jack (color-coded black) that provides a transformer isolated of both the diver and tender communications. It is designed to drive the standard line-level inputs of audio or video recorders with input impedances as low as 600 Ohms.

  • Can I use 40% nitrox gas with my Amcommand II?

    Yes, but we do not recommend using oxygen enriched breathing mixures above 40%.

  • Does the 8225-HP come with any documentation?

    Yes, an inspection report is included with each unit. The pneumo gauges come with a calibration certificate and sticker.

  • How can I test for a blown fuse on my Amcom II series communicator?

    If the unit is plugged into a live outlet and turning on the switch does not cause the AC POWER LED to light up, then the fuse(s) are probably blown. Unplug the unit from the outlet, remove the fuses and check continuity with a multimeter. Replace any fuse that does not show continuity.

  • Can you change the #6 JIC low pressure inlet fitting to a #8 JIC fitting on the 8225-HP Air Control?
    Yes, but that type of fitting can only be ordered in stainless steel and there will be an additional charge for changing the fitting. Please contact your sales representative for more information.

  • Is the 8225-HP2 IMCA compliant?

    No, the high pressure regulators are not independently routed and they share a common air manifold.

  • Can the pneumo gauge be ordered in meters of seawater?

    The gauges supplied with the 8225-HP and 8225-HP2 are dual scale in both feet and meters of seawater.

  • Can I operate my communicator while I’m charging the internal battery?
    Yes, however, the charger will charge the battery at a slower rate as some of the charger power is being used to operate the communicator. For the communicator only, units without options, about 20% of the charger’s power is being used by the communicator but units with HSU (Helium Speech Unscrambler) most of the battery charger energy is going to the communicator and HSU.

  • What is the input voltage range for the 2823-603 External Battery Charger?
    The 2823-603 can operate over an input voltage range from 90-264 VAC. It operates over an input frequency range from 47-440 Hz.

  • Why does the speaker on my communicator sound muffled?
    The simplest way to fix this issue is to unplug the red banana plug from the red microphone 5-way binding post on the communicator and rotate it 180 degrees then reinstall it. This should fix your problem. For a more detailed explanation of what happened, please read below. The issue is not with the communicator, it is with the wiring of the umbilical. There is always the potential for wiring the speakers and microphone out of phase, similar to wiring the speakers on a car stereo system. There is an orientation to the banana jacks and they should be wired for proper phasing with the communicator. A banana plug does have an identified ground side marked on the plug. Amron always sets up their umbilicals so that the ground side is located on the left side so the user can consistently plug in their umbilical and avoid phasing issues. If a banana plug is plugged upside down or is wired out of phase, the sound quality will be significantly reduced. If the phasing is out and the orientation of both plugs are the same, then the banana plug wiring should be reversed on “only one plug” to avoid this issue again. It does not matter which plug you choose to reverse the wiring on.
