Connections

EXP. and LCP. Connectors
Connect from the EXP connector on the back of the KP-812 keypanel to the Expansion 1 connector of
an optional EKP-812 Expansion Panel. Use the interconnect cable supplied with the Expansion Panel.
Note: JP1 must have pins 1 and 2 shorted to use the LCP connection.
Each LCP adjusts the listen levels for up to 16 keypanel keys, and you can connect as many LCP
panels as required to adjust all keys on the KP-812 keypanel and on an EKP-812 Expansion panel.
An interconnect cable is supplied with each LCP. Connect the first LCP to the LCP connector on the
KP-812. Connect the second LCP to the first LCP, and so forth.
Note: When arranging LCP panels in an equipment rack, you should put them directly above or below
the keys they will be used to adjust.
Frame Connector
Use either of the Frame connectors (but not both) to connect to an intercom port of the intercom
system. The intercom port you connect to should agree with the address that you set previously (for
more information on addressing, see page 29). Use the following cable diagrams to help you connect
your system.
