Qt 100 INTRODUCTION This manual covers system installation, masking level setting and system maintenance. This introduction section discusses guidelines to ensure effective sound masking coverage. The Qt 100 Configuration App Manual, shipped with our Bluetooth dongle, describes how the Qt 100 system can be configured using our companion iPad app. The Qt 100 control module supports one zone of sound masking with 2 cable runs. Each run supports up to 60 emitters.
OTHERWISE: If a sound level meter is not available, the recommended levels are likely to be achieved in most environments by setting the control module’s masking volumes as follows: Control Module’s Masking Volume Settings Private Office Zones 05-09, for all ceiling heights Open Area Zones 13-16, for 08 ft. (2.4 m) ceilings 15-18, for 10 ft. (3 m) ceilings 17-20, for 12 ft. (3.
Connections to the Front Panel Connect Paging or Music NOTE: The fixed terminal block can be removed for ease of connecting. Balanced Audio Input: (Most often, but not always characteristic of paging systems.) Connect signal wires to + and - at the input. Connect the shield to GND at the audio source. Unbalanced Audio Input: (Typical of music systems.) a. Mono Signals: Connect the mono signal wire to both L and R (split the wire) on the block. Connect the ground wire to GND. b.
Connecting Power The controller comes standard with a 24 V wall plug power supply. This supply features a wall plug and a fixed barrel connector. Alternatively, power can be supplied to the fixed block connector, which allows for stripped and tinned wires for added flexibility and convenience. The terminal block can be removed for easy wiring. Simply connect the positive and negative wires to the terminal block and slide the terminal block back onto the posts.
Installing Qt Emitters Important Considerations: • Each run has a maximum of 60 emitters! • Each run supports a maximum cable length of 1000 ft. • 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 "Zone Destination Record" at the end of this Guide. • The module has two identical outputs, Run 1 and Run 2. All emitters on Run 1 and Run 2 are controlled equally.
6. Connect a run cable from 7. Connect the next OUTPUT the specified OUTPUT jack cable to the emitter OUTPUT on the module to the INPUT jack. jack of the first emitter. Listen to each emitter as it is connected. If you cannot hear its “whooshing” sound: 8. Run the cable to next designated tile specified on emitter layout and wiring diagram. Tie cables up to a. Try a different emitter. structure or suspend from b. Test all four previous deck as required by local cables for continuity and shorts.
Custom Cabling Guidelines For system compliance, follow these guidelines if custom cables are required: 1. Use solid conductor 24 AWG CAT cable that meets local code requirements. 2. If the system is installed in a return air plenum, the cable must be plenum rated. 3. Shielding is not required. Unshielded twisted pair (UTP) cable is acceptable. 4. Snagless boots are not required. 5. RJ-45 plugs must use the “bent 3-tine” RJ 45 plugs intended for use with solid core CAT wire.
System Configuration via the Front Panel After the Qt 100 is mounted and the emitters have been tested, it is time to configure the Qt 100 for general operation. The front panel display shows system information and allows for adjustment of the masking and the auxiliary audio input levels. System Information Initial display of the front panel, shown below, shows the software version and system status. The VERSION X.X.X indicates the following fields: major release. minor changes .
Setting Sound Masking Level Masking Z1 Volume: Mute This figure shows that the format of the panel for configuring masking. Z1 stands for zone 1 and it is currently set to mute. The initial value of Mute is displayed. To adjust the level, use the up and down arrows while this screen is displayed. Settings within the recommended ranges (see page 3) should optimize speech privacy without excessive distractions.
Error Codes and Clear Error System errors are shown on the control module front panel display. If an error occurs, the message “Status: Error” will be displayed. To determine the cause of the error, press NEXT (right arrow button), to display the error code. Error Codes If one or more errors exist in the sound masking system, an eight digit error code is displayed on the LCD display (scroll forward to the “Error” screen).
Post Installation Handoff Perform a final walkthrough to satisfy all aspects of the system performance: 1. Fill out the settings record. 2. Store guide with completed settings record near the control module. If there is a hard module failure, the recorded values can be used to reconfigure the system. System settings are retained after a power outage. 3. Lock the control module panel by holding down the left and right buttons for 5 seconds.
