System Overview
The SoundAdvisor Model NMS044 noise monitoring system is the practical
solution to short- or long-term, unattended sound level monitoring. Power is
supplied by a 12-Volt battery, charged by a solar panel, which is positioned in
an area where sunlight is most available.

EPS044/NMS044 Features
1.
Reliable and Durable
The system
(including the battery, charge controller,
antennas, modem, and SLM) is enclosed in a
durable case. The environmentally-
protected, prepolarized microphone and
preamplifier provide reliable acoustic
measurements.
2.
Portable, Easily Deployed System
The system weighs as little as 50 lb (23 kg).
This enables one person to deliver and set up
the system in only a few minutes. The
NMS044 can be deployed, before, during, or
after you setup the 831C.
3.
Remote Connectivity
Access and
control the system remotely by connecting to
the gateway via a cellular network on your
mobile phone or PC. Using LD Atlas (mobile)
or G4 LD Utility (PC), view and download data
anytime.
4.
Low Power Consumption
When
enabled and used in conjunction with the low
power cable, the modem low power mode
runs basic features with exceptionally low
power consumption. When a solar panel is
part of the system, a minimal amount of
sunlight is needed to reboot in case a power
loss occurs. Using solar power, the system
charges to capacity in only a few hours.
5.
Continuous Sound Measurement
When using Continuous Run Mode, if the
battery is ever close to depleted, the system
is designed to save the current measurement
data and shut down safely. When the battery
is sufficiently recharged, the system powers
on and the previous measurement continues.
