Amron International

The Amron International Model 8111-01 One-Diver Air Control Surface Command Unit (SCU) is a compact, portable and affordable one-diver Surface Command Unit that includes a field-proven 2810E-03 AMCOM™ I One-Diver Communicator. This Surface Command Unit is a self-contained high/low pressure air control and depth monitoring (pneumo) system for surface supplied commercial diving operations.

WARNING: DO NOT USE THE AMRON 8111-01 FOR THE FOLLOWING

  • Mixed gas diving operations with an oxygen level greater than 25%.
  • Oxygen or oxygen enriched breathing mixtures above 25%.

Description

Features

  • The Amron International Model 8111-01 One-Diver Air Control Surface Command Unit (SCU) is compact and easily portable, and ergonomically designed with the customer in mind.
  • This air control system provides everything needed to safely monitor and control a diving operation.
  • Ideal for the inland diver, but rugged enough for the offshore diver, the 8111-01 is a great Surface Command Unit for any commercial dive environment.
  • The 8111-01 is a self-contained high/low pressure air control and depth monitoring (pneumo) system with a one-diver communicator for surface supplied diving operations.
  • The included 2810E-03 AMCOM™ I One-Diver Communicator and is a full-featured one-diver communicator with independent microphone and earphone volume controls for the tender and diver. The communicator can operate in both 4-wire (full duplex), or 2-wire modes. The communicator has a built-in internal charger and can be operated using a 90-264 VAC, internal 12 VDC battery, or an external 12 VDC power source.

High Pressure Side

  • High pressure air inputs include two color-coded (red & blue) SCUBA bottle yokes with six-foot air hose whips.
  • Standard 3000 PSI maximum input when using SCUBA yokes.
  • Optional 4500 PSI maximum input when using 300 Bar DIN Adapters, P/N: SAA-5300.
  • Each of the two HP inputs has a 0-6000 PSI gauge to monitor input pressure, and a shut-off valve to switch from one high pressure air source to the other.
  • The added safety feature of check valves provides protection against back flow of air from a full tank into an empty tank when switching high pressure air tanks.
  • High pressure air is reduced to low pressure via a pressure reducing regulator and a pre-regulator, in-line, 50 micron filter.
  • Output pressure is monitored using a 0-600 PSI gauge.
  • A relief valve (factory set at 285 PSI) prevents over pressurization.

Low Pressure Side

  • The LP input with safety check valve has a #6 JIC fitting and is protected from over pressurization by an over-pressure relief valve set at 285 PSI.
  • The input check valve provides simple switching to back-up high pressure air in the event of low pressure air failure. The high pressure air supply can quickly and simply be turned on.
  • The diver air hose connection is an O2 fitting controlled by a quarter-turn ball valve. Note: The O2 fitting can be optionally converted to JIC upon request at the time of order.

Pneumo (Depth Monitoring) System

  • At the heart of the pneumo system is a 6-inch precision gauge with 0.25% of full scale accuracy and dual scale readings of 0-250 feet of seawater (FSW) / 0-76 meters of seawater (MSW). The gauge dial has a mirror band and clearly marked one-foot increments for fast, accurate readings.
  • The regulating needle valve (with KEL-F seat) controls air to the pneumo gauge and a chrome plated, O2 fitting for the pneumo hose connection.

Communications

  • The 8111-01 comes standard with a field-proven 2810E-03 AMCOM™ I One-Diver Communicator.
  • This is a full-featured communicator with independent microphone and earphone volume controls for the tender and each diver.
  • The 2810E-03 communicator can be operated in either 2-Wire or Full Duplex (4-Wire) communication modes.
  • Audio input jacks on the front panel (2x RCA) are provided to connect external audio for diver entertainment (when using 4-wire, full-duplex mode comms).
  • A tape recording jack (RCA) is also included on the front panel.
  • The communicator has a built-in internal charger and can be operated using a 90-264 VAC, internal 12 VDC battery, or an external 12 VDC power source.
  • The battery life of a fully-charged 2810E-03 communicator is approximately 85 hours.
  • The communicator comes with Amron’s standard 2405-28 handheld, push-to-talk microphone.
  • Panel: Black powder coat over stainless steel with white silkscreen graphics.
