More Information
	FEATURES: The Amron International Model 8211-01 Compact Two Diver Air Control Surface Command Unit (SCU) is ergonomically designed with the customer in mind. This air control system provides everything needed to monitor and control a diving operation. The system is a self-contained high/low pressure air control and depth monitoring (pneumo) system with a field-proven two-diver communicator for surface supplied diving operations. Ideal for the inland diver, but rugged enough for the offshore diver, the 8211-01 is a great Surface Command Unit for either application. The system comes standard with a field-proven 2825A-07 AMCOM™ II 2-Diver Deluxe Communicator and is a full-featured, hard-wired, two-diver communicator with independent microphone and earphone volume controls for the tender and each 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. SPECIFICATIONS: 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 MAX input when using CGA850 yokes. Optional 4500 PSI MAX input using 300 Bar DIN Adapters, P/N: SAA-5300. Each input has a 0-6000 PSIG 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 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 with a pre-regulator, in-line, 50 micron filter. A 0-600 PSIG gauge monitors the output pressure. A relief valve (factory set at 285 PSI) prevents over pressurization. Low Pressure Side: An 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. Divers air hose connections are O2 fittings, controlled by quarter-turn ball valves permitting unrestricted flow. Note: O2 fittings can be converted to JIC upon request. 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. Pneumo (Depth Monitoring) System: At the heart of the pneumo system are two 4.5 inch precision gauges 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 dials have a glare free face, a mirror band, and clearly marked one foot increments for fast, accurate readings. Regulating Valve, KEL-F Seat: (2) with O2 Fitting Chrome Plated Brass. Hardwire Communications: The 8211-01 comes standard with a field-proven 2825A-07 AMCOM™ II 2-Diver Deluxe Communicator. This is a full-featured, hard-wired communicator with independent microphone and earphone volume controls for the tender and each diver. 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. It can be operated in both 2-Wire and/or Full Duplex (4-Wire) communication modes. Different modes can be used simultaneously. The communicator comes standard with Microphone Auto Detection that identifies the type of microphone each diver is using to automatically adjust for optimum performance. It can operate with any combination of both dynamic and pre-amplified microphones. 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 Advanced Communicator Features: Ultra-low noise circuit combined with noise suppression circuitry produces crystal clear speech. Automatic gain adjustment will guard audio signal from distortion and enhance speaker protection and audio quality, increasing the bandwidth 47%. The audio amplifier card employs a state-of-the-art, Class-D digital audio power amplifier. It has very low power dissipation, produces less heat, and extends battery life up to 32%. The audio amplifier card has adjustable gain settings to accommodate different communication applications and environments. EMI reduction is achieved through spread-spectrum and de-phase control techniques providing for optimum integration with diving systems. The built-in internal charger allows for simultaneous charging and operation of the unit while protecting the rechargeable battery from being overcharged. Automatically supplies power to the audio amplifier when AC power is disconnected to allow for continued operation.

FAQ's

What is the MS connector located on the top left corner of the communicator in the 8211 Series Air Control for?

The MS connector is not used on the 8211 series Air Control. If you own an 8211 series Air Control just keep this connector capped. The reason it is there is because this same communicator is used in Amron’s 8225 series Air Control and this connector is used to power the Low Pressure Alarm and sends audio to the speaker located in the pneumo panel.

What is the AC input voltage range for the 2825A-05?

The 2825A-05 has an input voltage range from 90-264 VAC and frequency range from 47-440 Hz.

How can I test for a blown fuse on my Amcom 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 stack the banana plugs from the diver's communicator cable so you can have two divers on each diver channel?

Although it may be possible, we strongly discourage such operation. The added workload would cause overheating and stress to the amplifier card. Prolonged use in this condition will eventually cause permanent damage and failure to the amplifier card.

What type of cable do I need to connect my Amron communicator to my Outland video system?

Amron communicators and Outland Technology’s video systems have a RCA Phono Jack. To connect the two systems together, you will need an audio cable with RCA Plugs on each end.

How do I install a new microphone in my Amcom II or III Communicator?

Please refer to the Panel Microphone Installation instructions located in the attachments tab.

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 fuse to blow on the amplifier card assembly. The power supply 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 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.

Can my Amcom communicator work on 240V / 60Hz?

Yes, the unit has an operating range of 90-264 VAC, 50-60 Hz..

When my battery does not appear to be holding a charge, how do I know if the problem is a bad battery or if the charger is broken?

To determine whether the problem is with the battery or charging circuitry, you will need to verify if the battery is being charged.

Troubleshooting:

Unplug your communicator and turn on the POWER switch.
Measure the voltage across the yellow PUSH-TO-TALK (PTT) jack and write down this value for future reference. It should be greater than 9 Volts.
Plug the communicator into an AC source and verify that the AC POWER LED on the front panel turns on.
Re-measure the voltage across the PTT jack and note it down for future reference. It should be higher than the previous measurement.
If the AC POWER LED does not light up when the communicator is plugged in, then check fuse located on the amplifier card.
Allow the communicator to charge overnight.
Unplug the communicator and re-measure the voltage across the PTT jack.
1. If it is the same or less than the voltage you measured previously, then the charger is broken and the communicator needs to be sent in for repairs
2. If the voltage higher than previous measurement but less than 13.5 Volts, then the battery is bad and needs to be replaced.
3. If it is greater than 13.5 Volts but it still appears that the battery is not holding a charge, contact Amron for additional support.
