INTRODUCTION
The Audiocom®1 BP-1002 and BP-2002 are microprocessor controlled
one- and two-channel intercom beltpacks. An internal switch and jumper
setting allows the units to be used with Clear-Com®2 components, if
desired. Other internal switch and jumper settings allow the unit to be
uniquely configured to the operator’s requirements.
OPERATION
SYSTEM POWER
The BP-1002 / 2002 beltpack receives power externally in one of two
ways:
• The intercom channel
• The local-power (pin 2) of the intercom channel connector
Both the BP-1002 and BP-2002 will pass system power through to
subsequent beltpacks that are “daisy chained” together.
INITIAL BP-1002/BP-2002 SETUP
The channel termination is initially set for balanced operation, which
is compatible with other Audiocom® equipment. If the unit is going to
be connected to Clear-Com equipment, one switch must be changed
as described in the section on Clear-Com Setup in this manual.
The headset microphone type is auto-sensing, which means it
automatically determines if an Electret or Dynamic headset is
attached to the unit.
