The SoundAdvisor
TM
Model NMS045 Permanent Noise Monitoring System is a
mounted, permanent noise monitoring system used for long-term outdoor sound
level monitoring. It is powered by one or two 12 V batteries which are charged by
a solar panel or an AC connection. The secure fiberglass case is equipped with an
intrusion detection device that will send a notification through the RV50X
Gateway Modem if the door has been opened. The gateway is used to connect
remotely to the SoundAdvisor
TM
Model 831C Sound Level Meter.
The NMS045 is not a product but rather the name for a set of products used with
the 831C sound level meter to create a permanent noise monitoring system.
