Introduction

• The TrojanLITE is an advanced noise nuisance recorder that has been designed to be simple to both setup and operate.
• The system features a precision data logging sound level meter which records both the noise levels and audio recordings over long periods of time.
• Once the equipment is installed and setup, the user has no control over the operation of the sound level meter which will measure and store noise levels for up to 30 days in a single session.
• The sound level meter is configured to store 24 hour blocks of measurement data, repeating until either the memory is full or the instrument is switched off.
• The only interaction needed by the user is to start and stop the audio recordings using the standard wireless remote control or the optional wired remote control.
• When the remote control is activated, the instrument will start to record audio and will continue to do so until the stop button is pushed on the remote control.
• If the user forgets to press stop, the instrument will end the audio recording after 5 minutes, whilst the measurement of noise levels continues.
• The system also features a pre and post trigger system that allows the audio recordings to include 20 seconds of information from before and after the user starts and stops the recording.
• If the power is removed, for example, if the user unplugs the mains power supply, the unit will run on its internal batteries for approximately 8 hours with a new set of batteries. Changing the batteries is covered in the optimus sound level meter user manual supplied with the TrojanLITE.
• If the power is reconnected before this time, the system will simply revert to mains power and continue unaffected.
• If the mains power is not reconnected and the internal batteries are run down, the instrument will store the noise data and audio recordings and then shut down safely.
• When the mains power is reconnected, the instrument will reboot and after 10 minutes (or when the remote control is pressed if this is sooner) restart measuring and storing noise data.
• This reduces the risk of data being lost when power is removed from the system.
• All of the measurements are stored directly to a high performance memory card which is internal to the system.
• The measurements are stored continuously which prevents data loss and ensures that the data cannot be tampered with or adjusted before it is downloaded to the reviewing software.

Getting started
It is recommended that you connect the sound level meter to the NoiseTools software and check that the instrument is configured as required before deployment.
See Appendix 1 Configuring the sound level meter for noise nuisance measurements for details of the configuration options that are specific to the TrojanLITE Noise Nuisance Recorder.
Connecting the cables
The TrojanLITE is shipped with the cables connected so that it can be setup quickly and easily.
The mains power supply and microphone cable can be disconnected from the case. This allows the cables to be replaced if they become damaged.
Connecting the microphone & preamplifier
The microphone and preamplifier are stored inside the case next to the sound level meter. Carefully remove the microphone & preamplifier from the case and connect to the microphone extension cable.

1. Align the pins in the preamplifier to the holes in the cable plug
2. Gently insert the plug into the socket
3. Tighten the Locking Ring so that it is finger-tight only
   DO NOT TWIST THE CABLE OR PLUG AS THIS WILL DAMAGE THE CABLE

Take care when connecting the cable to the preamplifier. The socket and plug will only connect in one orientation and care should be taken to ensure that the plug and socket are correctly aligned.
Mounting the microphone
The microphone and preamplifier are mounted onto a tripod which can be positioned away from the main case in the most appropriate location.
The tripod mount clips onto the preamplifier to hold it securely.
Attach the windshield to the microphone. The will help to protect the microphone from damage.

Switching on

• Connect the mains power supply to a socket and switch on the power.
• The Green Power Indicator on the Receiver unit will light up and the instrument will start.
• When the instrument has booted, the display will switch to showing noise levels.
• At the top of the screen the instrument will show Noise Nuisance View.
• The main display will show the current sound level as a 1 second LAeq value and the graph below shows the noise profile or time history.
• When the instrument is not running or recording, this graph will be displayed in green with yellow markers above showing the peak noise levels.
• The instrument is not recording or storing data at this point.
• If a measurement is not started within 10 minutes, the instrument will automatically start itself and will begin to record noise levels.

Check the instrument clock
All of the noise measurements and audio recordings made by the TrojanLITE are stamped with the current time and date. It is important that the internal clock in the instrument is set correctly.
At the bottom of the main screen, above the three soft keys, is the current time and date of the instrument. If this is not correct, press the menu key and select Set Clock.
Follow the instructions on screen to set the time and date.
Press OK and Back to return to the main screen.

Memory Size with audio recordings
Audio recordings take up much more memory than the noise levels measurements and so the TrojanLITE is fitted, as standard, with a 4GB internal memory card.
This allows the instrument to store up to 24 hours of audio recordings. The instrument will also store 30 days of noise level measurements alongside the audio recordings.

Calibrating the instrument

The instrument should be calibrated before each measurement. To calibrate the instrument, switch on the acoustic calibrator and verify that the green indicator light is showing on the calibrator.
Carefully attached the calibrator to the microphone and press the Calibrate key on the sound level meter.
The instrument will not perform a calibration. When this is complete and has been successful, the display will show 93.7 and the instrument is ready to be used.
Press OK return to the main screen.
Attached the windshield to the microphone to protect it from damage.

Starting a measurement
To start a new measurement, press the Start key on the sound level meter.
The first measurement will run from when the start button is pressed up to midnight. At that time, the current measurement will be stored and a new 24 hour measurement started. This will continue until the instrument is stopped.
The display will change and in the top left corner will be shown a red spinning indicator. This shows that the instrument is now measuring and storing noise levels.
The main screen will now show the overall LAeq as the large number with the current 1 second
LAeq and LAFmax shown below.
The graph will change colour from a dark green to a light green to show that the data is being recorded.
The case can be closed and locked ready for the user to make audio recordings.

Making a recording

Audio recordings are controlled by the Wireless RC:199 Remote Control.

Starting a recording

To start an audio recording, press the Record button on the Remote Control.

The red Indicator Light on the Remote Control will show when the key is pressed.

Recording Indicator on the lid of the case will flash blue and then turn red.

This can be seen on the top of the case and is labelled as the Record indicator.

When an audio recording is active, the graph on the instrument display will be coloured blue.

The noise level bar at the left hand side of the display will also be shown in blue and the Audio key will be highlighted.

The maximum length of a single audio recording is 5 minutes. This ensures that if the user forgets to stop the recording using the remote control, the memory of the instrument is not filled with excessive and possibly unwanted recordings. If the recording reaches the 5 minute limit, the instrument will automatically stop the audio recording and store the information. The measurement of noise levels will continue as normal.

Stopping a recording
To stop an audio recording, press the Stop button on the Remote Control.
The Record indicator will flash blue and then go out. The audio recording has now stopped. The sound level meter will continue to measure and store the noise levels.

Pre-Trigger & Post-Trigger
The TrojanLITE provides a Pre-Trigger and Post-Trigger function for the audio recordings. As standard, these are both set to 20 seconds.
When a recording is activated, the instrument will store the previous 20 seconds of audio from before the button was pressed and when a recording is stopped, the instrument will continue to store audio for a further 20 seconds.
When the Post-trigger is active, the Record indicator will not be lit but the audio will still be recorded.

Ending a measurement
To end a measurement, open the case and press the Stop button on the instrument. The measurement will be stopped and the data stored into memory.
If the instrument has been left unattended for more than 15 minutes with the case closed, the display will be switched off to reduce power consumption.
Press any key on the instrument to activate the display and then press the Stop button.
The instrument will show the overall LAeq,t and LAFmax values for the measurement. Press the Exit key to return to the main screen.

Packing away the instrument
Before packing the instrument away, switch off the instrument. Press and hold the power button on the side of the sound level meter until the instrument has switched off.
Disconnect the mains power supply from the socket.
The microphone and preamplifier can be stored in the case along with the wireless remote control units. This will protect the microphone from damage during transit and storage.

To remove the preamplifier from the cable, carefully loosen the Locking Ring until the cable can be removed.
Do not attempt to twist or turn the cable whilst it is connected to the preamplifier. This may damage the cable and prevent the instrument from working correctly.
Do not remove the microphone capsule from the preamplifier.
The microphone cable and mains power supply can be disconnected from the case if required. This is not essential and the cables can be stored in the backpack when connected to the main case.
Store the accessories such as the tripod in the backpack.

Downloading data to the NoiseTools software
The noise measurements and audio recordings are downloaded directly from the instrument into the NoiseTools software. This program allows measurements to be viewed and audio recordings replayed as well as reports created and analysis of the information to be made.
This section gives a brief overview of the software and the process to download, display and view measurements, as well as how to listen to an audio recording.
