Local Power Input (BP-2002 only)
Normally the BP-2002 is powered from the intercom
system and will turn on with the intercom system. The
BP-2002 belt pack may also be powered from an
optional power supply (18-30 VDC) connected be-
tween pin 2 (+) and pin 1 (-) of the intercom channel
connector.
8. INTERCOM CHANNEL CONNECTORS: On the BP-1002, the
intercom channel is connected via a pair of 3-pin
connectors (one male and one female). The male and
female connectors are wired together in parallel,
providing a “loop through” at each connector pin. Use
one connector to connect to the intercom channel.
Use the other connector to “daisy chain” a cable to the
next belt pack or other station on the channel.
OPERATING MODES
The microprocessor within the BP-1002/BP-2002
controls four modes of operation that affects the Microphone
Kill and Audible Call Alert features.
