1 INTRODUCTION
The Amron International AMCOM II 2820A-02 and 2820A-03 are full featured; two lock chamber
communication systems that provide reliable, two-way communications between the chamber
operator and occupants. Both models are used in conjunction with chamber talk back speakers such
as the Amron Model 3113, 3114, 3115, 3125 or 3126. The AMCOM II chamber communicators
include a rechargeable battery that maintains communication in the event of a power failure along
with a universal input 90-264 VAC, 47-440 Hz internal power supply. The 2820A-03 has all the
features of the 2820A-02 but also includes a separate entertainment amplifier circuit. This circuit is
used with the Amron Model 3130 Entertainment Speaker to provide audio entertainment to the
chamber occupants.
The AMCOM II Chamber Communicators have independent volume controls for the operator, inner
lock and output lock. There are separate on-off controls for each lock and both models are supplied
with the Amron Model 2405-28 Push-to-Talk microphone for use by the operator. The 2820A-02 and
2820A-03 can operate in 2-Wire or Full Duplex (4-Wire) modes as described later in this manual.
