POWER 24 VDC, 1.5 A DO NOT CONNECT TO DATA SYSTEM The system supports six zones of sound masking, each with 1 to 120 speakers covering 100 to 12,000 square feet per zone. Two audio inputs can be used for paging and/or music. Additional controls for each zone include time-of-day masking, auto ramping, self-monitoring 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 directly-connected computer OR by a computer connected through a local area network. See Front Panel Control and Software Control in the Operations Guide. Installing The Control Module Note: Always plug/unplug power supply at wall outlet. Wall Mount 1. 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 2. Plastic anchors are #10-12 x 1-1/4 with #10 x 1-1/2 screws. 2. Check to see that the panel lock switch is in the UN-LOCKED position.

4 Installing Qt PRO Emitters GENERAL NOTES: Each (home) run attached to the control module must be labeled by zone. Each zone has two identical outputs, run 1 and run 2. All speakers on run 1 and run 2 are controlled equally for each zone. Each job-made run should be manufactured according to ANSI/TIA/EIA Standard 568-B. See custom cabling guidelines on page 9. Job-made cables should be tested with a LAN tester before installation. Installation Order 1. Press + on the front panel and increase the output level of all zones to level 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 first 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. (Different types of emitter housings are available to attach in areas where there are no suspended ceilings) 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. 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. 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. 4

5 6. Connect a run cable from the specified zone output jack on the module to the INPUT jack of the first emitter. Listen to emitter as it is connected. If you cannot hear its whooshing sound, a. Try a different emitter. b. Test all four previous cables for continuity and shorts. Repair any faulty cables. c. If there is a short, masking the volume will shut off. The short should clear itself in approximately five minutes. If it does not, power cycle (unplug and re-plug) the control module. Be sure to fix any problems and hear the whooshing sound before installing the next emitter. If necessary see Errors in the Operations Guide. 7. Connect the next OUTPUT cable to the emitter output jack. 8. Run a patch cable to next designated tile specified 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 the front panel controls. Set sound levels according to Table 1. NOTE: The input jack of each emitter bears this symbol: The output jack of each emitter bears this symbol: Table 1 Zone Type Ceiling Height Vol. Level Intended Result Open Area dba Open Area dba Open Area dba Private Office ALL dba 5

6 Connecting to Software Installing a computer or network connection 1. Loosen screws A and B and hinge the control module forward. 2. Make a direct computer connection to the jack marked ETHERNET (see Figure 3) on the control module OR connect to a local area network (LAN). Figure 3 OR LAN 6

7 Installing Audio Inputs The Qt PRO s audio input expects a dry (no DC, no dial tone, no ringer voltage), line-level signal. It is important to understand what type of source signal you have, especially with paging, as there are varied paging source signals - some of which are incompatible with the Qt PRO s audio input. A phone system (PBX) is a common example of a paging source that offers different output signal types. If your paging source is a PBX, it is strongly recommended that you contact the PBX supplier to confirm that its paging output signal is compatible with the Qt PRO s audio input specification (page 11). If compatible, connect the PBX s paging port to the Qt PRO s audio input as shown below. If not compatible, you will need to obtain an expansion port for your PBX that is compatible with the Qt PRO s audio input, or deploy a paging controller designed to interwork various paging sources to a paging amplifier, such as the Qt PRO. Contact Steelcase Line 1 at 888.STEELCASE ( ) with questions. 1. Be sure power is OFF by unplugging power from wall outlet. 2. Balanced Audio Input: (For 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: (For unbalanced audio, typical of music systems.), A. Mono Signals: Connect signal wire to L at input A. Connect the ground wire to GND. B. Stereo Signals: Connect signal wires to L and R at input A. Connect the ground wire to GND. 4. If a music source is to be connected, use Input B to allow emergency music shut-off. See Contact Closures on page See Operations Guide for sensitivity settings and volume control. 7

8 Installing Contact Closures The Qt PRO 600 system 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 shut off Masking, connect a two conductor cable to the two connectors on the right, labeled M3V and MGND. To shut off Audio B Input, connect a two conductor cable to the two connectors on the left, labeled B3V and BGND. To shut off both masking and audio B, connect one wire to M3V and B3V. Connect the second wire to MGND and BGND. The associated audio function resumes automatically when the connection is broken. 8

9 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-tyne RJ 45 plugs intended for use with solid core CAT wire. Three tyne plugs can be purchased at Home Depot and from most CAT cable suppliers. DO NOT USE the aligned two-tyne type intended for stranded wire, as they provide improper contact and may yield intermittent system operation. The diagram below shows the end-on view of both types. 6. Field test each cable after fabrication with the RJ-45 connectors (before final installation), using a standard network LAN cable tester, to check for continuity, shorts, and 1:1 (straight through) connection. 2 types of RJ-45 connectors: CORRECT RJ-45 connector with bent tyne INCORRECT RJ-45 connector with aligned tyne 9

10 Post Installation Handoff Perform a final walkthrough to satisfy all aspects of the system performance: 1. Be sure zone destinations and volume settings are recorded in the Operations Guide. 2. Use the Print Settings tab on the Qt System Monitoring and Control Software to print all system information. 3. Store Installation Guide, Operations Guide and settings printout in the clear plastic job ticket holder next to the control module. Note: The administrator is responsible for maintaining a record of system settings. 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. 4. Lock the Control Module panel by moving the toggle switch to the Locked position. 5. Lift the control module front panel and hinge it backward into its closed position. Tighten all retaining screws. 6. If operating by software control, show the administrator how to connect to the Control module using both the Hostname and IP Address methods. NOTE: On Qt 600 systems, click the HELP tab in the application for detailed software control operating procedures. 10
