1.3 General Information
The Peninsula Engineering Solutions Microwave Repeater Monitor and
Alarm System, hereafter referred to as the RMAS-120, allows operators to
remotely monitor the status of Peninsula Engineering Solutions microwave
RF Repeaters. Remote monitoring improves the ability to maintain top
performance, minimize outages, and schedule routine maintenance for
equipment. In addition to alarm monitoring, the RMAS-120 alerts operators of
possible battery power failure several days in advance of the failure. The
RMAS-120 also reports key conditions such as amplifier status, battery voltage,
and temperature, and allows system operators to designate additional alarm
monitor points.
Both the transmitter and receiver modules of the RMAS-120 have LEDs (Light-
Emitting Diodes) for visual alarm indication and contact closures (opto-couplers).
The contact closures allow the operator to connect alarm information into a
standard supervisory system.
Standard RMAS-120 alarm equipment transports telemetry from the RF repeater
site by means of amplitude modulating the microwave carrier being repeated.
The microwave carrier is AM demodulated at the next microwave site by the
