1.1 | basic information on sound masking

You’re a Crucial Part of a Sound Decision

Working in an office environment poses a number of challenges to today’s workers; among them, performing at high levels with more distractions than ever before to contend with. You have been asked to play a part of the solution to two common and often-neglected problems: privacy and noise. Privacy and noise are big issues, especially in open office settings with a large number of workstations or cubicles. And notably, in healthcare and related service fields, protecting sensitive patient information is not just a top priority, it is the law. The good news: utilizing a sound masking system is a cost effective solution. As a qualified installer, you have become a crucial part of our client’s future office environment. The equipment you are installing will play a vital role in not only the privacy of our end user, but in their productivity and ability to concentrate as well. A successful sound masking installation, in fact, should enable the people who work in the environment to perform at their best.

You have been provided with state-of-the-art equipment and technology to install, test, tune and finalize. As such, your goals for the completed installation should be:

Tuning the system to the proper dB level

Achieving proper sound uniformity

Managing expectations for the product

Sound masking involves much more than a series of speakers, switches and wiring hidden somewhere above the ceiling. It has evolved into a science that literally affects the way a workspace works. Congratulations on being asked to perform a vital service for this client. You will leave the workspace a better, more focused place to work. Those who will benefit from your efforts will be better workers, and their companies more efficient, and you will have made a contribution to their future success!

WHAT IS SOUND MASKING?

Sound masking is a means of adding background sound to a work environment to make

conversations more private (speech privacy) and to reduce extraneous conversations and noise.

Masking systems have an integrated sound source, an amplifier, an equalizer, and

speakers that produce and carry an electronic sound that should be barely perceptible, non-directional and harmoniously uniform throughout a given space.

section 1

1.1 | basic information on sound masking

You’re a Crucial Part of a Sound Decision

HOW DOES SOUND MASKING WORK?

Sound masking works because it changes the ‘dynamic range’ of sound in an environment. Typically, the dynamic range in most environments is large, meaning that there is a great degree of difference between the lowest, or ambient, sound level and the highest levels of sound, when people are actively speaking and working. Work environments are perceived as noisy precisely because of this large dynamic range. The higher dB sound of normal speech is easily heard in a backdrop of a lower, ambient background sound. Sound masking works by subtly raising the ambient background sound level, thereby reducing sound’s dynamic range. This effectively “masks” unwanted noise, makes speech unintelligible (creating privacy), and makes the work environment acoustically comfortable.

WHAT ARE THE CRITERIA FOR PERFORMANCE?

The sound from a masking system must accomplish two things:

It must mask speech (providing measurable speech privacy)

It must not be a distraction (must be a “comfortable” sound)

GETTING A COMFORTABLE SOUND

How do you add sound with a masking system so that the system itself is not distracting or annoying? The answer is by properly tuning the system to meet the needs of the space. Lencore's system, when tuned properly, is very comfortable while also creating speech privacy.

A sound masking system must be tuned so that the frequencies fall within the preferred sound masking curve. The system should also utilize tight tolerances for the decibel (dB) level within the space.

Spatial uniformity is also critical to a comfortable sound. Follow the tuning section carefully and please call Lencore's main office if you have any questions.

PREPARATION

Review boxes. Refer to packing list and check equipment in boxes. Be certain you have:

All Operating Platforms – Please secure all OPs to a very safe place.

i.LON (make sure you secure the i.LON – approximate cost $2000.00).

The terminator(s). Keep these in a safe place.

Power supplies, MPI (headend enclosure).

Speaker boxes. Count all the items to ensure that you have all of your equipment.

Open speaker boxes to properly count the number of speakers you have.

Review Wiring and Installation Drawings:

Verify where wiring will be installed BEFORE placing equipment.

Check wiring runs to properly estimate needed quantity of wire for the project.

Check quantity for: Power Wire (16/2), Data Wire (CAT 5e, 4 pair), Speaker Wire (CAT 5e, 4 pair). Check that all wiring is Plenum Rated, Only use Plenum Rated wiring in Plenums. Verify where OPs and speakers will be installed. Please note OPs need

to be installed in sequence.

Review location for placing the head end equipment (electrical or IT closet) – make

sure that you have access to power in the closet. Follow all safety precautions. Use a UPS (uninterruptible power supply) for powering the head end for all emergency paging systems. Check for and identify intended placement for the:

Wall mounted enclosure or rack mounted drawer

Identify any major site impediments such as:

Slab-to-slab wall

Shafts

Risers (wiring raceways from floor to floor

Obstructions in plenum

REMINDER

Secure all OPs, MPI AND i.LON equipment on site.

Store securely & safely.

OPs, MPI AND i.LON are

expensive items!

section 5

5.2 | i.Net OP and speaker placement

Place the

approximate installation locations.

Place

Make sure the OPs are not put in harm’s way of people working or walking.

NEVER PLUG AN i.NET OP INTO ANY COMPUTER OR NETWORK EQUIPMENT OTHER THAN AN i.LON OR ANOTHER OP.

NEVER INSTALL POWER WIRES WHILE THE POWER IS ON. IT IS DANGEROUS AND WILL DAMAGE THE OPs, ONLY TURN THE POWER ON WHEN THE POWER WIRES ARE FULLY AND PROPERLY WIRED AND INSTALLED.

INSTALLATION

IMPORTANT: Lencore suggests installing equipment in this sequence:

i.Net speakers by walking the floor and set the speakers on the floor at

OPs

on the floor at approximate locations (check drawing for correct sequence).

Hang speakers*

Hang OPs

Run wire with power OFF

ATTENTION: DO NOT HOOK UP POWER UNTIL THE SYSTEM IS FULLY INSTALLED. POWER CONNECTIONS MUST BE DOUBLE-CHECKED TO ENSURE PROPER POLARITY.

CRITICAL: CHECK WIRING POLARITY (+ AND -) BEFORE FIRING THE SYSTEM ON, OTHERWISE, IRREVERSIBLE DAMAGE WILL OCCUR TO SOME OR ALL OF THE OPs.

* Speaker units will hang from the ceiling using the attached chain (supplied by Lencore). Chain length should be cut to enable each speaker to hang a minimum of 6” above the ceiling tile and a maximum of 12” above the ceiling tile, unless otherwise noted on the drawing.

NOTE: TO HELP MAINTAIN UNIFORMITY, KEEP THE CHAIN LENGTHS/HEIGHTS CONSISTENT THROUGHOUT THE INSTALLATION AND SPACE.

HELPFUL HINT

It may be helpful to mark each speaker with a magic marker on the bottom for each OP, each

channel and speaker number, for example: OP #1, channel 1 - mark the speaker OP1A. Also when you

get to the end speaker on each channel, add “END” to this designation.

section 5

5.3 | hang speakers

Climb ladder and access the ceiling plenum

Hang speaker units in plenum area at marked locations using preferred hanging method (powder action gun such as a Hilti-gun™ or drill and screw; check your local building codes for allowable hanging methods and standards)

Drive a nail holding the clip with the speaker chain and speaker into ceiling

Pull and connect audio cables to speakers by channel

* keep speakers installed at very

consistent heights

6"-12"

NOTE: If installing inline speakers, make sure the potentiometer on the bottom of the speaker is set to the MAXIMUM (clockwise) setting.

IMPORTANT

Follow channel designations

on drawings (1,2, 3,…8) so

that proper tuning of the system

can take place. Any changes

to the system MUST be

designated on the drawing

section 5

5.4 | hang i.Net operating platforms

You have received i.Net OPs pre-numbered – see label on each i.Net OP indicating its sequence number. Check and install each respective i.Net OP according to the drawing.

i.Net OPs are hung from the ceiling using the attached chain (supplied by Lencore). Chain length should be cut to enable each speaker to hang 6-12” above the ceiling tile or 3” below the ceiling deck. Make sure air can circulate around the i.NetOP and that the i.Net OP is not touching metal in the ceiling or plenum.

NOTE: Keep the chain lengths/heights consistent throughout the installation and space.

IMPORTANT: Lencore suggests installing equipment in this sequence:

Climb ladder and access the ceiling plenum

Hang i.Net OPs in plenum area at marked locations using preferred hanging method (powder action gun such as a Hilti-gun™ or drill and screw; check

your local building codes for allowable hanging methods and standards)

Drive nail holding clip to i.Net OP chain and i.Net OP into ceiling

NOTE: Do not permit the i.Net OPs to touch any other metal in the ceiling. Isolate each i.Net OP with wire ties.

section 5

Data cables (CAT 5e or equivalent – 4 pair – Plenum Rated) – Straight Pin 568B Method

Speaker Cables (CAT 5e or equivalent – 4 pair – Plenum Rated) – Straight Pin 568B Method

PREPARATION

Check site drawing for wiring installation diagram

Use wiring diagram to determine approximate wiring lengths:

Approximately 15’ between speakers (Cat 5e 4 pair)

Approximately 3000’ total Data length

(AE Router needed at that point to extend distance)

IMPORTANT: Double-check for long home runs and runs between floors, as these will require much longer lengths of wire. Check wiring schematics for your project.

For more detail about system wiring, see Section 4 – data cables

POWER CABLES

Power cables are plenum-rated, 16-gauge, two conductor cable

•

One power supply powers 3 i.Net OP's with paging and/or music (6 OP's masking only)

•

A common ground must exist

•

Between i.Net OP to i.Net OP

From the MPI located in the Lencore enclosure to the first i.Net

OP Between Floors

WARNING

NOTE: Do NOT activate power until the Power wires are checked for proper polarity and all

the i.Net OPs are wired for power in a power zone. DO NOT SKIP THIS STEP!!! If proper

polarity is NOT maintained, then irreversible damage to the OPs will occur.

DO NOT CONNECT OR DISCONNECT i.NET OPs WITH LIVE WIRE

as injury and shock may occur, and damage may be caused to the equipment.

section 5

5.5 | wiring the speakers and i.Net® ops

First, run power cables to the IN/OUT connections of each i.Net OP,

taking care to be consistent with positive and negative screw terminals.

Do NOT cross positive and negative connections while wiring power- irreversible damage will occur.

Run the power cables (NOT LIVE) from the power supply unit in the electrical/ IT

closet to the power +/- screw terminal connections of the first i.Net OP.

Complete all other wiring (audio and data) and perform wiring checklist

BEFORE powering up the system.

WARNING

NOTE: Make sure that grounds are connected to grounds and positives

to positives, and that wires are not crossed anywhere in the entire system.

Double check the wiring at each power supply.

Follow all labeling for power.

section 5

5.6 | power supply

WHEN AN ADDITIONAL POWER SUPPLY NEEDS TO BE ADDED:

Typically, one power supply is needed for 3 i.Net OP's with paging and/or music (6, masking only).

WIRING BETWEEN POWER ZONES:

Add a ground wire between OPs (negative or conductor wire). DO

NOT CONNECT THE POSITIVE WIRE BETWEEN OPs.

Be sure ground cable is run between i.Net OPs.

Use the (-) Negative terminals IN and OUT appropriately.

NOTE

section 5

5.7 | installing power supply for other i.Net® ops

INSTALL THE POWER SUPPLY

Mount the power supply unit to the wall in a secure location as close to each i.Net OP as

possible. Use angle brackets and screws for mounting. Exception: 1st power supply in Lencore branded enclosure for SmartSwitch and 1st i.Net OP.

Keep top fan and side vents exposed!

Take note of the three (3) positive and three (3) negative power terminals.

Do not plug in until system is completely wired and checked for polarity (see schematics on page 23).

WARNING

NOTE: DO NOT PLUG IN UNTIL SYSTEM IS COMPLETELY WIRED AND CHECKED FOR

POLARITY. Irreversible system damage will result if polarity is not kept.

section 5

5.8 | proper wiring

IMPORTANT! DAMAGE CAN OCCUR!

Check polarity of all wiring! If continuity is reversed with regard to the power CABLING (16 gauge, 2 conductor) at any point, some or all of the OPs will be irreversibly damaged.

MAKE SURE THAT between power zones a ground wire is ONLY installed connecting the separate power zones/supplies.

MAKE SURE THAT YOU have connected to each Power Supply the correct wire to the low voltage side AND that each wire is correctly connected to the appropriate and proper + and -. VISUALLY INSPECT AND DO NOT LEAVE TO CHANCE!

MAKE SURE ALL OPS ARE WIRED CORRECTLY

AND FOLLOW CONTINUITY THROUGHOUT

THE ENTIRE SYSTEM (+ AND –).

You may turn on each power supply in sequence.

Visually inspect to insure that the i.Lon® server and MPI (if one is purchased for the project) are properly wired and installed.

ONCE YOU HAVE VISUALLY INSPECTED EACH ITEM AND ESTABLISHED CONFIDENCE THAT THERE IS CORRECT CONTINUITY THROUGHOUT THE POWER WIRING, YOU MAY PROCEED TO THE NEXT STEP!

5.13 | handheld remote

USING THE HAND HELD REMOTE:

Each OP is equipped with an integrated infrared eye on the bottom of the OP enclosure allowing remote usage and connectivity. Using the Spectra i.Net® hand-held remote control point the remote to the bottom of the OP enclosure for IR line of sight control. Adjustments to the OP may be made from the remote control for masking volume and masking contour or paging volume or music volume by either single audio channel or entire OP.

section 5

5.13 | using the handheld remote

You will also notice that the green LED light will stay lit while the remote is depressed, visually cueing that the remote is working and the OP is responding to the remote’s signals.

When you are satisfied that the space has been tuned to the proper dBA level and has achieved proper sound uniformity, you can close up the remaining ceiling tiles to complete the project. Remove any debris created on site and contact your project team leader or Lencore to let them know the work had been completed.

Tuning the sound masking correctly is extremely important. The measure of the projects success will be measured by the quality of the sound. Ensure that the correct and appropriate amount of time is spent tuning and fine tuning the entire project.

5.15 | IR Hub

Each OP is equipped with an integrated infrared eye on the bottom of the OP enclosure allowing remote usage and connectivity. Using the Spectra i.Net hand-held remote control, point the remote to the bottom of the OP enclosure for IR line of sight control. Adjustments to the OP may be made from the remote control for masking volume and masking contour or paging volume or music volume by either single audio channel or entire OP.

Each OP is also equipped with an IR port on the side of the OP enclosure. This port allows an IR keypad to be installed via plenum rated CAT 5e wire and an RJ45 connector from the OP located in the ceiling plenum to the space below the plenum, in a location along a wall, similar to that of a normal wall switch. This setup allows for IR keypad use without having to remove a ceiling tile.

The IR Hub is an additional component that allows for more than one keypad to be installed in an OP IR port giving a single OP audio channel specific control to a respective keypad. Up to four keypads may be installed in each hub allowing four keypads to be installed per each OP.

At the last i.Net OP:

Run the last data cable to the IN jack of the last i.Net OP in

the project.

In the last i.Net OP, click the data terminator into the data OUT jack. This should only be installed in the last i.Net OP.

In the last i.Net OP, run a cable from the data OUT to the head end equipment in the data closet. This will connect to the data IN from the last i.Net OP on the SmartSwitch.

The Music and Paging Interface (MPI)

The MPI is an optional system component. It sequences the OPs and has inputs for: The i.Lon® network hub Music Paging

FOLLOW THESE STEPS TO INSTALL THE MPI:

Mount the MPI to the wall

Connect the MPI to the i.Lon® using two conductor/one pair wire (16 gauge).

Connect each wire to the screw terminal on bottom of MPI to the i.Lon®.

I.LON CONNECTIONS

One wire to #17 (LON® B/PLT-) One wire to #18 (LON® A/PLT+)

When installing the i.Lon®’s data connection to the MPI, polarity is unimportant, however, make sure the two wires at the screw terminals are clean and not touching or crossed.

Coming out from the MPI, use a data cable, 4-pair CAT 5E with an RJ45 connector.

Plug into the 10/100 Ethernet base connection from the MPI to the data IN port of the first OP.

You must also connect a ground wire from the MPI to the OP that Connects the MPI ground to the OP ground.

7.2 | final wiring checklist

FINAL WIRING CHECKLIST BEFORE POWERING UP SYSTEM

Have you checked all home runs?

Have you checked all wiring between floors (risers)?

Are you sure all grounds are properly tied between i.Net OPs?

Have you made sure all Data and Speaker wires are tested and installed?

Check polarity of all wiring throughout, especially power cables. If continuity is

reversed at any point, some or all of the i.Net OPs will be irreversibly damaged.

NEVER WORK WITH POWER WIRE, OR CONNECT POWER WIRES TO I.NET OPs, WHILE POWER IS ON.

TIP

TIP! Check data wires by going to the Sound

Manager Congurator and

refreshing i.Net OPs after

each i.Net OP is connected. This will help to eliminate large

trouble shooting issues

at the end of the job.

WARNING

NEVER WIRE or CONNECT

POWER TO AN i.Net OP WHILE

POWER IS ON!!! i.Net OP will
