• To connect an unbalanced (single-ended) paging signal, connect the signal wire to + and connect the ground wire to both – and GND, using a shunt wire between – and GND. IMPORTANT: When installing cables for Zone 1 (connectors on the door), leave sufficient length so that the front door can be fully opened with cables securely tied to the door. Measure with the door fully open. • If a network attachment is made, confirm that a connection is made.
To Install Emitters: • Refer to emitter layout drawings provided by dealer. • Remove and gather all ceiling tiles that are to receive an emitter. • Using the supplied hole saw, cut holes (front to back) in each ceiling tile that will receive an emitter. • Cut in the center of a 2' x 2' tile. In other tile sizes, cut as appropriate to achieve required spacing. • Cut all tiles at once to save time. • Gently push the emitter through the hole from the front of the tile.
ACCESSING, SETTING AND OPERATING THE SYSTEM Each Qt PRO™ unit ships ready to be used as either a standalone system or a network-connected system. STANDALONE MODE (FRONT PANEL CONTROL) Qt PRO™ can be controlled from its front panel.(Some features are only available in Networked mode.) + PREV NEXT - To control Qt PRO™ from the front panel: • Set the Panel Lock switch to the UNLOCKED position. (Refer to diagram on page 2.) If the LCD display is blank or difficult to read adjust LCD contrast (+ or –).
• If an error has been detected, the Error screen is displayed. Click on + to acknowledge the error. • If the unit has been configured for time-of-day operation or if auto-ramping is on (in “Networked Mode”) the masking volumes displayed are the current volumes and the control panel warns the user that time sensitive operations have been configured. If this warning is presented, it is best to change Qt PRO™’s masking volumes from a browser.
To control Qt PRO™ from a browser: • Connect Qt PRO™ to a LAN. Read the unit’s Hostname or IP Address from the front control panel and enter it into a browser’s address bar. The computer must have network access to the unit. A user name and password are required to access the unit. The default Username is “admin” and the default Password is “secret”. Once you log into the unit you may change the Hostname, Username and Password. DHCP support • Qt PRO™ uses DHCP to obtain its IP address.
Other Required Connections • The unit requires access to a SMTP server for sending error notification emails. Do not allow email replies to the unit. • The unit requires access to an SNTP server for obtaining an NTP time stamp. The unit sends its SNTP request to “pool.ntp.org”. • If software updates are to be performed, the computer running the Qt PRO™ System Monitoring and Control application requires TFTP access to the unit.
Setting the masking volumes can be approached in two ways: IDEAL: If a sound level meter is available, adjust the unit’s masking volumes to achieve the following readings on a sound level meter.
Paging Sensitivity Key – – – – – 0 – – – – 1 – – – 2 – – 3 – 4 0 dB + 5 6 + + 7 + + + 8 + + + + 9 + + + + + 10 • To configure paging, set Paging A Sensitivity to zero then set Paging A Volume for Zone 1 (Z1) to about the midpoint (attach an emitter to Zone 1 so you can hear the test pages). • Next, have someone speak continuously into the paging system. Increase Paging A Sensitivity until their voice becomes audible and continue until it distorts.
If you are using a browser, subsequent adjustments are automatic and you may disregard the information below. • If you are managing Qt PRO™ from the front control panel, set the unit’s masking volumes to be 6-10 levels lower on Day 1. Using the control panel, make a +2 level adjustment before each workday begins, until you reach the permanent masking volumes. POST-INSTALLATION HANDOFF • Perform a final walkthrough.
Custon Cabling Guidelines If it is necessary to create custom cables on site, must follow these specifications to ensure compliance with the Qt PRO™ equipment. you Any quality solid conductor 24 AWG CAT cable is acceptable, provided it meets local code requirements and: 1) Meets requirements for plenum installation (plenum-rated) if installed in a return air plenum. Shielding is not required. Unshielded Twisted Pair (UTP) cable is satisfactory. Snagless boots are not required.
Errors If an error is detected, “Status: Error” will be displayed on the Version, Status screen (control panel) or on the Operations page (browser). To learn the cause of the error, press NEXT (if using control panel) to proceed to the Error screen or click on Error (if using browser). You must acknowledge the error to clear the error register. Click + (control panel Error screen) or Acknowledge (browser) to clear the error.
Conversion Key Each alphanumeric digit identifies a certain type of error for the corresponding system or zone: ERROR CODE AMP SHORT 0 SYSTEM/AMP OVERHEAT HARD FAULT: Call Dealer NO ERRORS 1 2 3 8, 9, A, B Note that the specific digit can indicate multiple errors as shown in the table. For example, “Status: 003000” indicates both an amp short and an amp overheat in Zone 4. SPECIFICATIONS POWER SUPPLY: modular 100-240 VAC 50/60Hz 1.5 A input; 15 VDC 4A output; CE/UL/CUL rated.
harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his/her own expense.
SETTINGS RECORD Installer / Administrator If Qt PRO™ is controlled from a network browser, use the “Print Settings” link under the Administration page to print out a complete set of system information. Place printout with the unit. Otherwise, fill in details below. This is critical to ease recovery from a hardware fault.
