connected via a pair of 6-pin connectors (one male and one female). The male
and female connectors are wired together in parallel, providing a “loop through”

Normally the BP-2002 is powered from the intercom system and will turn on
with the intercom system. The BP-2002 beltpack may also be powered from
an optional power supply (21-30 VDC) connected between pin 2 (+) and pin
1 (-) of the intercom channel connector.
