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.
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.
Qt 300/600 Introduction Installing the Control Module NOTE: Always plug/unplug power supply at wall outlet NOTE: The Qt 600 is shown in the figures, 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 ¼ inch drill bit for the anchor hole. See Figure 1. Plastic anchors are #10-12 x 1¼ in. with #10 x 1½ screws. B A Figure 1 GND -/L R M3v Bgnd Check to see that the panel lock switch is in the UN-LOCKED 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. A Step 1 Remove the QtPro and power supply bracket from wall mount bracket. B Step 2 Reassemble power supply to right rack mount bracket using 6:32 black screws (included with bracket). Step 3 Fasten left and right rack mount brackets to QtPro using the screws removed in Step 1.
Installing the Qt Emitters Important Considerations: ▪▪ Each run has a maximum of 60 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.
NOTE: 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. NOTE: To adjust for unexpected obstacles such as sprinkler heads, each emitter may be moved up to two feet (one tile) in any direction, if necessary. 7. Connect the next OUTPUT cable to the emitter OUTPUT jack. 8. Run the cable to next designated tile specified on emitter layout and wiring diagram.
Installing Paging or Music to the Audio Inputs 1. Be sure power is OFF by unplugging power cord from wall outlet. 2. 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. Unbalanced Audio Input: (typical of music systems.) a. Mono Signals: Connect signal wire to both L and R at input A or B. Connect the ground wire to GND. b.
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.
Battery Replacement A coin-style battery (Cr1220 or Br1220) powers the real time clock during a power loss. To replace the battery: 1. Unplug the control module from wall outlet. 2. Hinge the control module forward to access the connection panel. 3. Remove the zone run connections. They should already be labeled, if not, label before removing (for example: Zone 1 Run 2). 4. Remove the six screws that hold the panel. 5.
System Configuration After the QtPro is mounted, the power can be turned on and settings modified to test wiring to the connected emitters. After testing, it is time to configure the controller for operations. There are two methods for performing configuration: 1. The front panel display can be used for basic configuration settings to get the system working and tested. In many cases, basic settings are all that a user needs. This interface only supports a subset of the functionality. 2.
Configuring the Control Module for the Network IP Address DHCP The IP address is preset for systems that are not on the network. To directly connect to the control module over Ethernet, the user uses any internet browser and places the IP address or control module name in the navigation bar. If the MCS is not used, DHCP will allocate an IP address when the system is connected to the network. This field can be statically set through the MCS, but it will be dynamically allocated when MCS is not used.
Front Panel Control The front panel is used for configuring basic functionality and initial system test. For advanced system configuration, the MCS is required. Once the MCS is used to configure the system, using the front panel will erase the settings configured by the MCS. Once the MCS is used to configure the system, it should be used exclusively. System Information Initial displays of the front panel, shown below, shows the software version and system status. The VERSION X.X.
Hostname is set at the factory to a default value. This can be changed through the MCS. Host Name QT XX The next 2 blocks show the username and password when connecting using MCS. The default is admin/secret. These can be changed at the MCS window. Username admin Password secret A warning message is displayed on the front panel after the MCS is used for configuration (Warning: Time of day Ops).
If installation occurs before the office is occupied, turn the system to the desired level and leave it at that level. If the system is installed after the office is occupied, turn the system to the correct level when the space is unoccupied and employ auto ramping, only supported through the MCS, to provide for a period of acclimatization.
Setting Audio Input Levels Input A Z1 Volume: 6 This figure shows the format of the panel for configuring the volume for input A or B. The level of the input is set for each zone, where the example shows Input A is level 6 for zone 1. The system has two inputs for paging or music. Either input may be connected to any or all zones via software or front panel interface. If no paging and/or music from these inputs are desired in a particular zone, set the audio volume level of that zone to mute.
Configure Network Name and IP Address Creating a static IP address or controller name is not available from the front panel. The MCS software can configure both the network name and the IP address (see below). If the system is not connected to the network, the initial values shown on the front panel are used when connecting a PC to the QtPro over Ethernet. If the QtPro is connected to the network, a DHCP server will dynamically allocate an IP address.
System Control Using Monitor Control Software (MCS) The MCS (Monitor Control Software) is an interface that configures the QtPro over a LAN/network connection. The MCS software is operated from any network browser. Below are the instructions to connect to the control module over Ethernet locally and over the network. After the discussion on connecting to the control module, the MCS screens will be discussed. Connecting to the Qt 300/600 over Ethernet 1. System software is operated from any network browser.
MCS: Operation Screen Figure 12: Operations Section in review mode. Note: The software version is displayed at the bottom right of every screen. The 3 digits indicate major release version, minor feature changes and bug fixes. There are times when Cambridge Sound Management will release software to fix unique bugs or small feature changes, and later roll them in to a major release. When a customer reports a problem, the software version number is usually requested.
Changing Masking Level Using MCS Follow these steps to update the parameters within the masking level block: 1. Review – selecting the review button will allow the user to select a zone and see the current configuration. Click on the zone on the right side of the operations screen. 2. To modify a zone, start by clicking the modify button. 3. Select the zones to modify by checking the boxes of the zones on the right side of the operations screen. 4. To set the masking level, use the multi-select for max.
Example: Zone 1 is planned to be masking level 9. Auto Ramping is set to -15dB. On day one, the level is active 15dB less than the planned level. Day 2, it is only 14 dB lower. It rises each day until it is functioning at full masking. Changing Input A and B Level The control module operates as a paging amplifier. Refer to the control module’s specifications for the electrical characteristics of Inputs A and B. Each signal is routed to all zones.
Select Line Level to use the signal as it comes to the controller and adjust volume from the zone window. Use Boost to add 10 dB to the signal and then continue the adjustment of volume in the zone window. Time of Day Masking QtPro allows the specification of a max time masking volume and a min time masking volume for each zone. This allows complete flexibility to when the masking level needs to be high or low.
Errors If the control module is operating properly, software will display “Status: Ok”. If the control module encounters an error, software will display “Status: Error”. Click on “Error” to obtain additional information. Click on “acknowledge” to clear the error (see Administration: Notification of Errors, page 28). If the error condition persists, the error will be signaled again after clearing the error.
Service The service window holds the following fields: Control Module Name: This is just a reference name for the control module and is not used for networking. An example of an informative name is “120 Main Street - First Floor”. Location: This is a good reference to track where the control module is located when faults are detected. Faults can be sent via email and the control module’s location can be useful. Serviced By: This is for getting help when there are errors/ problems.
The “Email Address” is the address to which error notification emails will be sent by the control module. The “Email Server” and “Port” are the name (i.e., smtp.mymailservice.com) of the mail server and the port that it listens to for outbound SMTP. If authentication is required, fill in the “Username” and “Password.” Otherwise, leave them blank. “Username” and “Password” represent the control module’s email account on the specified mail server.
the “Simple Network Time Protocol” protocol) or “RTC” (Real Time Clock). WARNING: Manually changing the RTC’s time/date via the “Administration: Date and Time” window should not be attempted between the hours of 12:00 AM and 2:00 AM on DST transition days (two per year). Doing so could result in a missed “spring ahead” or “fall behind” event. Set the date and time before midnight on a DST transition day or after 2:00 AM on a DST transition day.
privacy. The report is shown in the Masking Equalizer control box and is stated in terms of change to the Privacy Index. A change must be at least 1% for it to display. The calculation is performed as specified in “ASTM International; Designation: E1130-02, Standard Test Method for Objective Measurement of Speech Privacy in Open Offices Using Articulation Index”. Figure 15: Operations Section with the equalizers block displayed after a higher level password has been entered.
Figure 16: Standard view of the ENFD configuration section. The diagram above shows the window as it appears and is learning the network configuration. After the 15 minutes are expired and the system is fully installed, it is time to enable fault detection if you desire. It is not required for proper operation. The window shown on the next page shows that after the 15 minutes have expired there is a dropdown in the upper right corner that allows 3 actions: 1.
Figure 17: ENFD adjustment drop-down view MCS: Help The following section will use figure 18 for reference. Links to Help Topics From the Help screen on the MCS, there are links to some common questions when using the MCS. The links are shown on the right under Operations and Administration. This information is also contained within this document. Software Update This is a link to the Cambridge Sound Management web site for access to the latest software.
Figure 18: MCS Help Section The install directions are provided with the new software for convenience and not part of this document. MCS: Printout This screen displays the current configuration of the system. This screen should be captured and stored in case of data loss or system failure. Printing is done through the web browser print option. Error Codes and Messages Front Panel System errors are shown on the control module front panel display.
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). The error state is indicated by an eight digit code of the form: Error: 0_000000 Error Code for Zone 1 Error Code for Zone 2 Error Code for Zone 3 Error Code for Zone 4 Error Code for Zone 5 Error Code for Zone 6 Reserved Error Code for Control Module Where a number other than “0” indicates an error.
Selecting “Error” for the screen above pops open a window that details the error in the system. The format of the error string is the same as shown on the front panel. The screen below shows there are emitter faults in 3 zones and the administrator should look for nonfunctional emitters. Click OK to close the window. Click the acknowledge link and the status goes back to OK. If the error persists, the status will show the error. This can be used to test problem resolutions.
