Amcom II 2-Diver Deluxe Portable Non-Rechargeable Communicator (Lantern Batteries)

The Amcom™ Series 2825A communicator is the most versatile and powerful two-diver communicator on the market today. The most unique is the design of separate channels and volume controls for each diver and the tender, both for the uplink and the downlink paths. Each diver may have different equipment such as microphones and speakers or different listening and speaking characteristics. You can set the volume for each diver and tender to the individual comfort level. Both divers can be set up on 2-wire and/or 4-wire mode, or one-diver on 4-wire mode and the other on 2-wire mode or any combination of the two modes.

Features

  • Volume setting for each diver and tender to their individual comfort level
  • Both divers can be set up on 4-Wire Mode or 2-Wire Mode or any combination of the two modes
  • Ability to use both dynamic and preamplified diver microphones with a unique circuit that detects microphone type and automatically adjusts volume levels
  • Weatherproof panel microphone for greater voice intelligibility
  • Communicator can be left on charge indefinitely without damage to the batteries or communicator (/23 and /24 versions only)
  • Communicator can be operated directly from the charger where AC power is available (/23 and /24 versions only)

Product FAQ's: 

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

Answer: 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.

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

Answer: 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.

Question: 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?

Answer: To determine whether the problem is with the battery or charger you will need to verify if the charger is properly charging the battery.

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 this AC POWER LED does not light up when the communicator is plugged in, then check fuses F1 and F2 on the charger Printed Circuit Assembly (PCA). Allow the communicator to charge overnight. Unplug the communicator and re-measure the voltage across the PTT jack. 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 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. If the voltage higher than previous measurement but less than 13.5 Volts, then the battery is bad and needs to be replaced. 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. less than 13.5 Volts, then the battery is bad and needs to be replaced. 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.

Question: Can you stack the banana plugs from the diver's communications cable so you can have two divers on each diver channel?

Answer: 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.

Question: What is the electrical protection (IP) rating on the AMCOM II 2825A & 2825R Communicators?

Answer: We have never had any official testing performed but we estimate the IP rating, assuming all gaskets are properly maintained at:

  • 2825R Rackmount Series: IP61
  • 2825 Portable Series: Case Closed - IP67, Case Opened - IP66
