Emitter Installation
(continued)
Basics of Qt X 300/600 outputs: maximum signal run, channel definitions, output
run architecture and spacing in small rooms per ceiling height. See Figures 16-18.
Channel Designations per Run
Output X - Run A - A,B,C,D,A,B,C,D,A,B,C,D...
- Run B - C,D,A,B,C,D,A,B,C,D,A,B...
Maximum Signal cable distance ≤ 1000 ft (304.8m)
Qt Passive emitters
Room Control (QT-RC3 - Accessory option)
VERY IMPORTANT:
Use of the Qt-RC3 room control is ONLY recommended for
zones broadcasting background music or paging and only when the control needs
to be accessible by building occupants. Qt-RC3 room controls should NOT be used for
user control of sound masking signals except in some unique healthcare applications.
Consult the Cornerstone document <
> for more information. NEVER use Qt-RC3
room controls for private office control of sound masking signals.
The Qt Room Control can be used to adjust the sound masking level for an
individual room or a space with up to 8 Emitters. Room Controls can be placed in
the cable run and will count as 2 passive emitters in the total number of devices
per run. They do not count against the device total if used with Active emitters.
