Qt 300/600 Introduction

This manual discusses the installation of a sound masking system using either the Qt 300 or the Qt 600. The Qt 300 and Qt 600 controllers have identical functionality, but different number of zones supported - the Qt 300 supports 3 zones whereas the Qt 600 supports 6 zones. As you use this guide, remember the number of zones and total area of coverage is the only real functional difference between the systems. Collectively, the systems are referred to as ‘QtPro’ throughout this guide.

The Qt 600 supports six zones of sound masking, each with 1 to 120 Standard Emitters covering 100 to 12,000 square feet (9.3²) - 1,115²) per zone. The Qt 300 supports three zones of sound masking, each with 1 to 120 Standard Emitters, covering up to 12,000 square feet per zone (1,115²).

Sound Masking Emitter Types

There are two different sound masking emitter choices for consideration, both are direct field devices meaning that they are mounted downward for direct unimpeded transfer of an audio signal to the listening location.

Qt Standard Emitter – Is a passive audio loudspeaker device suitable for sound masking and limited output level paging applications. This emitter receives an amplified signal directly from the QtPro control processor via a UTP category cabling infrastructure. Maximum sound pressure levels with this type of emitter are 55 dBA at 1 meter with a sound masking frequency response of 200Hz to 6.3kHz.

Qt Active Emitter – Is an active (self-powered) audio loudspeaker device suitable for sound masking as well as paging/ background music environments. This emitter contains an internal amplifier which receives the audio signal directly from the QtPro control processor in addition to a direct current voltage which powers the Qt Active Emitter device. Both power supply(s) and voltage injectors are required for operation in addition to the QtPro control processor. Maximum sound pressure levels with this type of emitter are 74dBA @ 1 meter with a sound masking frequency response of 125Hz to 8kHz.

Each system comes with two audio inputs which can be used for paging and/or music. Additional controls for each zone include time-of-day masking, auto ramping, selfmonitoring fault detection and notification, and independent equalizers for masking and audio inputs. The system may be operated from its control module front panel or by a computer directly connected to the module or by a computer connected through a local area network. See system configuration on page 15.

It is important that the control module’s masking volumes be set correctly for each zone to obtain the full effectiveness of the system. If volumes are set too low, speech privacy will be reduced and work place distractions will be much more apparent. If volumes are set too high, the masking sound itself could become a source of distraction. The higher the setting that can be used comfortably, the better the acoustic privacy. For a given open office design, including ceiling height, ceiling material and workstation panel height, we can define the masking volume required to achieve “normal acoustic privacy,” i.e., when it is relatively easy to ignore surrounding conversations. For a very large range of open office designs, the target level is in the 45–48 dBA range, measured 3 ft (0.9 m) above floor level. Similarly, for private offices, based on wall panel design and ceiling construction, we can define masking volumes required to achieve “confidential privacy,” i.e., conversations in adjacent offices cannot be understood. Most private offices have a target level in the 38–42 dBA range, averaged spatially within the office.

Setting the masking volumes can be approached in one of two ways:

BEST: If a sound level meter is available, it is recommended that the control module’s masking volumes be adjusted up or down to achieve the following readings on the meter:

• Private Office Zones: 38-42 dBA, averaged spatially within the office

• Open Area Zones: 45-48 dBA, measured 3 ft (0.9 m) above floor level

OTHERWISE: If a sound level meter is not available, the above levels are likely to be achieved in most environments by setting the control module’s masking volumes as follows:

• Private Office Zones: 05-09, for all ceiling heights

• Open Area Zones:

• 11-14, for 8 ft (2.4 m) ceilings

• 13-16, for 10 ft (3 m) ceilings

• 15-18, for 12 ft (3.7 m) ceilings

Masking volumes must be set sufficiently high to improve speech privacy and reduce distraction but not so high that the masking sound becomes objectionable. Settings within the above ranges should accommodate both objectives. As a general rule, use the high end of the range. Base final settings on site conditions and customer preferences. If people object to the sound level, set masking volumes toward the bottom of the range or refer to the ‘Ramping’ section of this guide, found on page 22 for more information on introducing masking into the space gradually. Remember that the effectiveness of the system relies on sufficient masking sound level and that initial objections are often overcome as people become accustomed to the sound.

Different day and night volumes may be set. The control module ramps linearly between these two settings beginning at the time specified and over the period of time specified. As the control module ramps between settings, the current volume is displayed under “Current”.

NOTE: This document uses the QtPro software version 6.6.0 or higher for feature

conguration.

Hardware Installation

Installing the Control Module

NOTE: Always plug/unplug power supply at wall outlet.

NOTE: The Qt 600 is shown in the gures, but the Qt 300 installs in the same manner.

Wall Mount

Mount the bracket using the three screws and plastic anchors (mollies) provided. Use a 1/4 inch drill bit for the anchor hole. See Figure 1.

Plastic anchors are #10-12 x 1 1/4 in with #10 x 1 1/2 screws.

NOTE: The control module hinges forward for wall mounting and cable installation. To hinge forward, loosen screws A and B (see Figure 1) used to secure the module during shipping.

Check to see that the panel lock switch is in the UNLOCKED position.

Rack Mount

Attach optional rack mount brackets to each end of the control module.

NOTE: When rack mounted, the control module does not hinge forward.

1. Remove the QtPro and power supply

bracket from wall mount bracket.

2. Reassemble power supply to right

rack mount bracket using 6-32 black screws (included with bracket).

3. Fasten left and right rack mount

brackets to QtPro using the screws removed in Step 1.

4. Mount QtPro to 19” cabinet rail using

10-32 screws as shown (included with bracket).

Installing the Qt Emitters

Important Considerations:

• Each run has a maximum of 60 Standard Emitters or

• 50 Active Emitters

• Each run should have a maximum length of 1000 ft (305 m).

• Each home run cable attached to the control module should be labeled by zone # and run #. Adding a logical name (e.g. Marketing, Private Offices) is suggested. In addition, fill out “Home Run Zone Destination Record” at the end of this Guide.

• Each zone has two identical outputs, run 1 and run 2. All emitters on run 1 and run 2 are controlled equally for each zone. All emitters per zone must be the same type (Standard or Active).

• Each job-made cable should be manufactured according to ANSI/TIA/EIA Standard 568-B. See custom cabling guidelines on page 13.

• Job-made cables should be tested with a LAN tester before installation. Adjustable emitters should be set for lower sound levels, within a zone, when sound level measurements show an acoustically loud subsection.

Standard Emitter Installation

1. Set the masking output level of all Standard Emitter zones to level 20.

2. Refer to the emitter layout and wiring diagram provided by the dealer for cable run connections by zone.

3. Run home run cables from control module to the location of the rst emitter for all runs in all zones.

4. Gather all ceiling tiles (per layout drawing) that are to receive emitters. Use the supplied hole saw to cut holes in designated tiles. Cut all tiles from the front.

(Di󰀨erent types of emitter housings are available to attach in areas where there

are no suspended ceiling tiles.)

5. Push the emitter through the front of the hole in tile and secure it by pushing down and twisting the locking ring at the back of the emitter.

NOTES:

• The “tombstone” hook on the back of each emitter is next to the INPUT jack.

• This can help you find the INPUT jack by touch.

• To adjust for unexpected obstacles such as sprinkler heads, each emitter maybe moved

up to 2 ft. (one tile or 0.6 m) in any direction.

6. Connect a run cable from the specied zone OUTPUT jack on the module to the

INPUT jack of the rst emitter. Listen to each emitter as it is connected. If you

cannot hear its “whooshing” sound:

• Try a different emitter.

• Test all four previous cables for continuity and shorts. Repair any faulty cables.

• If there is a short, circuit protection will engage, and masking volume will shut off. Once

the short is fixed, the protection state should clear itself in approximately five minutes.

7. Connect the next OUTPUT cable to the emitter OUTPUT jack.

8. Run the cable to next designated tile specied on emitter layout and wiring diagram. Tie cables up to structure or suspend from deck as required by local building code.

9. On the next emitter, connect this cable to the INPUT jack.

10. Repeat Steps 4 through 9 for the remaining emitters on the home run.

11. Set sound masking volume levels for each zone, using either the front panel controls or the software interface. Set sound levels according to Table 1.

12. If a small area within a zone exhibits a perceived volume louder than the rest of

the zone, due to a di󰀨erence in acoustics, use the adjustable rocker switch on

the back of each related emitter to turn the volume down (by 3, 6, or 9 dB from the value set at the controller). See emitter spec sheet for more details.

Be sure to fix any problems and hear the “whooshing” sound before installing the next emitter. If necessary see the Error Codes section of this guide, found on page 31.

Active Emitter Installation

Before masking output volume can be set for zones with Active emitters, the emitter Type and Masking Spectrum for those zones must to be configured within the MCS software. Refer to the MCS Operations section later in this document.

NOTES:

• The input jack of each emitter bears this symbol and is located near the safety tie off.

• The output jack of each emitter bears this symbol.

Private O󰀩ce Areas ALL 4-8 38-42 dBA

Installing Paging or Music to the Audio Inputs

1. Be sure power is OFF by unplugging power cord from wall outlet.

2. To install balanced audio input (most often, but not always characteristic of paging systems): Connect signal wires to + and - at input A or B. Connect the shield to GND at the audio source.

3. To install unbalanced audio input (typical of music systems):

• Mono Signals: Connect signal wire to both L and R at input A or B. Connect the ground

wire to GND.

• Stereo Signals: Connect signal wires to L and R at input A or B. Connect the ground wire

to GND

4. If a music source is to be connected, using Input B allows emergency music

shut-o󰀨. See Installing Contact Closures below.

Intended Result

(at listener ear level)

Installing Contact Closures

The QtPro provides an instant shut-off capability for masking and/ or audio Input B if connected to a contact closure interface. The contact closure utilizes the same style connector as audio Inputs A and B (4-pin).

To leverage this feature for masking, connect a two-conductor cable to the two connectors, labeled M3V and MGND. To leverage this feature for Audio Input B, connect a two-conductor cable to the two connectors, labeled B3V and BGND.

The other end of these conductors (treated as pairs/circuits) can be terminated on closure mechanisms of your choice:

1. To shut o󰀨 masking, form a connection between the two “M” conductors.

2. To resume masking, break the connection. (Don’t break the connectors as you may want to reuse them.) The contact closure for audio Input B follows the same logic.
