2.4 CONNECTIONS
2.4.1 Mic Connector
To connect a panel microphone, such as the RTS model
MCP5 or MCP6, screw the microphone into the Mic
connector on the front panel of the MKP-4.
☞
For Mic connector specifications, see page 8 .
2.4.2 Headset Connector
The Headset connector accepts a monaural, dy-
namic-microphone headset (headphones and micro-
phone). If you use a headset, make sure DIP switch 4 is
set to the Open position (page

Alternatively, headphones can be connected when a panel
microphone is used for talkback. Or, a handheld dynamic
microphone can be connected when a speaker is used for
listening. If you use either of these special configura-
tions, make sure DIP switch 4 is set to the Close position
(page
9 ).
☞
For Headset connector specifications, see page 8 .
2.4.3 Speaker Connector
The speaker output can be used for listening when a panel
microphone is used for talkback. If you use this configu-
ration, make sure DIP switch 4 is set to the Open position
(page
9 ).
The speaker output can also be used for listening when a
handheld microphone is used for talkback. If you use this
special configuration, make sure DIP switch 4 is set to the
Close position (page
9 ).
☞
For Speaker connector specifications, see page 8 .
2.4.4 Connection To Intercom System
Use a standard RTS intercom cable. Either a 9-pin or
RJ12 type can be used. Refer to Figure
3 or 4 . Plug one
end of the cable into the appropriate Frame connector on
the back panel of the keypanel. Plug the other end into the
appropriate port of the intercom system. (This will be the
port number that you designated previously when setting
the Address switch.)
☞
Keypanels may be connected while the intercom
system is running.
☞
Note that 9-pin intercom cables for use with an
ADAM CS frame must use special connectors at the
intercom matrix end as described in Figure
3 .
