ADVANCED FEATURES
APPENDIX A - Monitor Override
The way that the MONITOR function works is dependant on the configuration of the
three jumpers P1, P2, and P3 on the back of the master next to the terminal block for
the green wires. The MC602 comes from the factory with only the P1 pins jumpered
(the other jumper is on only 1 pin of P2 in case it is needed). In this configuration the
monitored room does not hear any intercom communication or the chime.
The MC602 can also be configured for MONITOR OVERRIDE. This is done by
removing the jumper from the P1 pins, inserting it on both P3 pins, and moving the P2
jumper onto both P2 pins. (A pair of needlenose pliers may be necessary to move the
jumpers). In MONITOR OVERRIDE the monitored room hears all intercom
communications including the chime.
APPENDIX B - Station Scanning
The way that the SCAN function works is dependant on the configuration of the two
jumpers P1 and P2 behind the face panel just above and to the right of the display on
the master. The following table shows how the SCAN function operates:
