Module 1 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.

Figure 1-1 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.

All features of the firmware option are accomplished by using G4 LD Utility software. For

more information, contact your sales representative or see the SoundAdvisor 831C

Manual, Module 6, which is available on the included Larson Davis USB drive or at

www.LarsonDavis.com.

Software

LD Atlas App for Mobile

With an established cellular connection, you can use the LD Atlas app to communicate

with the SoundAdvisor™ 831C SLM. LD Atlas is available for Android® from the Google

Play Store®, or for IOS® from the iTunes Store®1. To install the app: open the app store on

your mobile device, search for “LD Atlas,” and follow the prompts.

1.3 Understanding NMS044 Power Consumption

We recommend the following three ideas to make the most of your available power. The

first is a basic formula you can use to estimate your system’s daily power consumption.

The second is to employ the modem low power feature as an effective means to decrease

system power consumption. The third is to explore helpful resources to better

understand the recommendations and requirements of using a solar panel to recharge

battery power.

In this section:

• Estimating Power Consumption

• Understanding the Modem Low Power Feature

• Making the Most of Your Sunlight Hours

Estimating Power Consumption

To estimate how much power your system requires per 24 hours, use the formula shown

in Figure 1-7.

1. See the inside front cover of this manual for trademark information.

NMS044 Reference Manual Understanding NMS044 Power Consumption 7

Figure 1-7 Formula for Average Watt-hours Used Per Day

To estimate the system run time in days, based on the available battery power, calculate

the following:

Figure 1-8 Formula for Days of Available Battery Power in Watt-hours

Understanding the Modem Low Power Feature

Modem Low Power is an 831C system property that can be enabled or disabled to

facilitate your use. When enabled, the gateway is powered down except for these

periods:

• when the 831C SLM powers it on to send alert notifications

• when the SLM sends a file to the cloud (SFTP, Dropbox, etc.)

• During the scheduled awake period (via 831C-SCH optional firmware add-on)

An NMS044 system purchased later than July 1, 2020 comes ready to use modem low

power, with the power cable (CBL222LP) and SLM firmware (version 4.5 or later). To

prepare an NMS system purchased prior to July 1, 2020 for low power, see “Updating

NMS044 for Modem Low Power” on page A-8 .

When modem low power mode is used in conjunction with the 831C Scheduling option

(add-on 831C-SCH), additional power savings and regulation are possible. This option

allows you to schedule measurements as well as periods when the modem uses low

power. For more information on the 831C Scheduling option, open G4 LD Utility, and

navigate to Help Manuals G4 LD Utility ManualModule 6.3.
