NORMARC 7050 USER MANUAL MARKER BEACON audio signal in the Power Amplifier (PA). The PA is capable of delivering up to 4W power at 97% depth of modulation. Unwanted frequencies are removed by a lowpass filter after the PA. 3.3 Monitors / Transmitter Control The marker beacon has one or two MO1374 monitor modules depending on model (Table 31). The MO1374 is mainly a microprocessor based module.
USER MANUAL NORMARC 7050 MARKER BEACON The Remote Control Unit is connected to the MB by one pair telephone cable. 3.6 Remote Maintenance Monitoring (RMM) The NM7000 series has a built-in Remote Maintenance Monitoring system. This system consists of the RMS system, remote PC terminals with the RMM program installed, and the local keyboard/display. Figure 3-2 illustrates the RMM/RMS systems.
NORMARC 7050 USER MANUAL MARKER BEACON The local keyboard/display allows readings and controls through an LCD display and a sevenbutton keypad. This gives access to the RMM functionality without the need for a PC. 3.7 RMM Access Access to the RMM system is controlled by multiple hardware and software access controls. One password is required for each access level, i.e. one password for level 1, two for level 2 and three for level 3.

NORMARC 7050 USER MANUAL MARKER BEACON 6 Antenna Normarc supplies single and dual antennas, NM 3561 and NM 3562 respectively. The single antenna may be used for inner, middle and outer marker, while the dual antenna is specially designed for outer markers. The advantage of the dual antenna is a lower spread in FLYING THROUGH TIME inside the localizer coverage area. In addition to two antenna elements, the monitor and distribution network DI 726 is included in NM 3562.
