1.4 PERFORMANCE REQUIREMENTS
A.
The Classroom Lighting System shall consist of: pendant luminaires with specified ballast
factor, lamps with specified lumen output and CRI, Intelligent Classroom Control Module
(CCM), Teacher Control Center (TLC), SD Commissioning Card, Low Voltage A/V
Dimming Control (if specified herein),Low Voltage Switch and Entry On/Off Station(s),
faceplates, occupancy sensors, daylight sensors (if specified herein), Plenum-rated LowVoltage Control cables with modular connectors, and control components.
B.
The pendant luminaires shall contain two rows of 48-inch fluorescent lamps whose
primary luminous distribution is upward and one center row of 48-inch fluorescent
lamps whose primary luminous distribution is downward. These rows shall be dual
switched per information to follow.
D.
The control system shall consist of:
1. Classroom Control Module (CCM). The CCM shall consist of a UL or cUL US
listed enclosure including both line voltage and low voltage components
wherein the low voltage connections are separated from the line voltage via UL
compliant barrier. CCM shall require only one 120 or 277V line voltage input
location where power shall feed into CCM and out to lighting luminaires.
a) CCM shall provide function labels for both line voltage and low
voltage system components. Low voltage to be color coded at input
port; line voltage to be labeled for input and output at relay panel.
b) CCM shall include, as standard, LCD user interface screen with
scrolling menu, SD card e-commissioning interface, demand response
interface and option board location built in. The CCM shall provide
forward compatibility without the need to replace CCM or CCM mother
board and shall include firmware upgradeable via SD card interface.
c) CCM shall include dry contact for demand response interface if desired
d) CCM shall support up to four rows of GEN/A/V lighting and one
whiteboard or three rows of GEN/A/V lighting and two whiteboards.
e) CCM shall allow operation of GEN/A/V lighting rows to vary function
and type by row if desired. Example: Rows 1, 2 and 3 Daylight
dimming using 3 lamp lighting luminaire, Row 4 Daylight Hi/Low
Switching using 2 lamp lighting luminaire.
2. CCM: Verification of Control Commissioning. CCM shall provide the ability
to produce a time and date stamped documentation file indicating real time
settings of controls configuration parameters for verification purposes through
SD-card interface. Verification as a function of the CCM shall provide the
ability to re-verify at will; real time, time and date stamped, control
configuration parameters using SD-card interface. Instructions shall be
provided to owner, facility manager and specifier on how to obtain CCM
control parameter verification at will. Inclusion of instruction and
documentation shall be a function of commissioning party.
3. Teacher Lighting Control Station (TLC). A Teacher Lighting Control Station,
defined as a multi-gang control switch selection, shall be provided with
recommended placement located near the teacher’s primary teaching position.
TLC shall provide, at minimum, a method for switching between general
ambient and audio-visual lighting and a Study Time switch (defined later in
this document). Additional functions may be selected for placement in the TLC
if indicated on plans and schedules.
4. TLC: GEN/A/V Switch. Teacher will select general ambient lighting on,
“General” (GEN), or audio-visual lighting on “Audio Visual”, A/V. The
buttons on the switches in the Teacher Station will be labeled GEN and A/V
accordingly. In a three-lamp cross section, GEN and A/V functions shall be
interlocked except as required to prohibit transient intervals of darkness when
switching between GEN and A/V lighting modes. See also NeverDark feature
as described in section (5).
5. TLC: GEN/A/V: Never Dark feature. NeverDark feature shall encourage the
use of recommended occupancy sensor / frequent switching ballast technology
(program rapid start) ballasting without loss of light to the classroom as modes
are changed. When the instructor changes between GENERAL (GEN) and
Audio Visual (A/V) modes the lamps from the mode being switched off will
remain lit as the lamp(s) in the mode being engaged are switched on. Once the
desired mode has been lit the lamp(s) in the mode being switched off will then
disengage. The brief and transitional interval where all lamps are lit shall
prevent disruptions of light level in the classroom as the teaching method
changes between modes. NeverDark feature shall not exclude interlock
programming of a three lamp cross section luminaire during normal function to
prohibit all three lamps being energized in any state other than the transitional
NeverDark state. NeverDark shall be a function of firmware rather than
hardware and, therefore, shall be an inherent function of the TLC GEN/AV
switch requiring no manual control on the part of the teacher or control
operator.
6. TLC: Study Time Switch. Study Time Switch shall be ganged for inclusion in
the TLC as standard. The instructor will have, as standard, an LED indicator
switch with button labeled Study Time. Study Time switch, when pressed
momentarily, shall send a signal to the occupancy sensor which will cause the
occupancy sensor to assume room occupancy even in the absence of motion for
a period of time as programmed in the firmware of the CCM.
a) Study Time switch shall include, through firmware, the option for
programming of cycle time from 0 to 240 minutes according to
education level of the room; specification shall default to 60 minutes
unless noted.
b) Study Time with LED switch shall include a cycle elapse warning
indication: during the last two minutes of the Study Time (starting at
58 minutes for a 60-minute setting) the LED indicator will blink to
indicate that the Study Time cycle is nearing completion.
c) Study Time button may be pressed momentarily at any time during the
Study Time cycle to return to the start time of the cycle and LED
indicator will remain or return to solid, non-blinking lit state as a clear
indication that the switch is engaged.
d) Study Time may be ended at instructor’s discretion at any time during
the cycle by a press and hold operation; LED indicator will go dark
when Study Time has either fully elapsed or terminated through
manual press-and-hold command.
e) While in Study Time mode the instructor will have full control of the
classroom lighting.
7. Master Entry Low Voltage On/Off Switch. A single entry point low voltage
switch with two buttons labeled ON and OFF shall be provided for entry at one
primary entrance point. Additional, optional master entry switches shall be as

include a color coded sticker for identification of the color code and the CCM
connection shall be to a color coded port with optional port number assignment
laid out by design engineer if indicated. Where multiple entry or row switches
are used they may be ganged together or jumped via low voltage color
appropriate CAT5 cable; connections between devices of similar color coding
shall be allowed.
8. (Optional) Row Entry Low Voltage On/Off Switch(es). In leiu of, or in addition to
Entry Low Voltage Master On/OFF switch, row switches may be elected. Each Row
switch shall be low voltage, requiring no line voltage connection to switch or switch
station. Row switch button shall be single button with Row number as indicated. Up to
four Row On/Off buttons are available as an option. Row buttons shall be stand-alone
or ganged together using yellow color coded CAT5 cable and returning to CCM
yellow port. Port numbers shall be assigned, if desired, by design engineer. See above.
9.
(Optional) Manual On/Automatic Off. Where requested by specifier and indicated on
purchase order, CCM shall be programmed to require occupancy detection through
Manual On with Occupancy detection for automatic off. Functionality of Manual
On/Automatic Off shall be a firmware function uploaded and implemented at time of
system commissioning. Where used, Manual On function will occur through manual
press of either Master ON or Row switch(es) and occupancy sensor will be method
used for automatic shut-off.
10. Occupancy Sensor. Occupancy Sensor shall be shall be ceiling-mounted and
connect to the lighting system through low-voltage snap-together method.
Manufacturer shall supply cable with pre-installed Quick-to-InstallTM
connectors at one end and CAT5 low voltage cable at the other end. The sensor
shall turn lights on when both PIR and ultrasonic sensors detect occupancy.
Once on, detection by either sensor will keep the lights on. A field adjustable
time-delay shall be factory preset to recommended NEMA standards.
Sensitivity settings shall adjust automatically through InteliDaptTM integrated
sensor technology. Occupancy sensor shall return to the CCM using a low
voltage, color coded white CAT5 cable connection into a numbered white color
coded port. CCM Port number may be assigned, if desired, by design engineer.
11. (Optional) TLC: A/V Teacher Dimming. The A/V section of a luminaire shall

buttons showing raise/lower icons. A/V Teacher Dimming will be placed, if
elected, into the Teacher Lighting Control station unless noted.
12. (Optional) TLC: GEN Teacher Dimming. The GEN lighting of participating
luminaire(s) shall be dimmed to 5% of the initial light level using a low voltage
switch with buttons showing raise/lower icons. GEN Teacher dimming, if
elected, will be placed into the Teacher Lighting unless noted for placement
elsewhere in the room.
13. (Optional) Daylight Control: Switching. Daylight Sensor shall be ceilingmounted facing the primary window wall and located approximately one-half
way between the first row of luminaries and the wall or at a 45° view of the
primary sunlight fenestration where side lighting is indicated or facing up into
the skylight well where toplight is indicated. It shall provide for adjustment of
light level setting between 3 and 6,000 footcandles through both minor
hardware adjustment and CCM firmware programming. CCM shall accept
footcandle readings of the room upon commissioning to allow each
participating Daylight Dimming (DD) row to switch general ambient light
individually based on the single signal from the Daylight Sensor. The Daylight
Sensor shall interface with the Classroom Control Module (CCM) to provide a
single signal parsed to all participating Daylighting general ambient lighting
rows via CCM instruction to said lighting rows. It shall provide for an
adjustable dead band setting to prevent lighting system cycling. The Daylight
Control sensor shall be connected via low voltage plug-and-play cable using
Quick-to-InstallTM connection at one end and CAT5 cable connection to CCM.
Sensor will be factory calibrated to reduce the field commissioning time to
calibrate the units.
14. . (Optional) Daylight Control: Dimming. Daylight Sensor shall be ceilingmounted facing the primary window wall and located approximately one-half
way between the first row of luminaries and the wall or at a 45° view of the
primary sunlight fenestration where side lighting is indicated and facing up into
the skylight well where toplight is indicated. It shall provide for adjustment of
light level setting between 3 and 6,000 footcandles through both minor
hardware adjustment and CCM firmware programming. The Daylight Sensor
shall interface with the Classroom Control Module (CCM) to provide a single
signal parsed to all participating Daylighting general ambient lighting rows via
CCM instruction to said lighting rows. CCM shall accept footcandle readings
of the room upon commissioning to allow each participating Daylight
Dimming (DD) row to self-adjust via 0-10V dimming signal individually based
on the single signal from the Daylight Sensor. Daylighting fade and ramp-up
rates shall be preset in firmware but may be adjusted, if desired, through the
CCM firmware. Daylight Dimming will include SmartSense feature to provide
for switching off of general ambient lighting when daylight is sufficient to
maintain dimming at low end of dimming range (defined as 1.5 volts unless
indicated) for a period of time (defined as 10 minutes unless indicated). If these
conditions are met the ballast will switch off at the low end of the dimming
range and will return to operation at the low end of the dimming range when
return to electric illumination of general ambient lighting is deemed necessary
by the CCM based on daylight readings and commissioned parameters. The
Daylight Control sensor shall be connected via low voltage plug-and-play cable
using Quick-to-InstallTM connection at one end and CAT5 cable connection to
CCM. Sensor will be factory calibrated to reduce the field commissioning time
to calibrate the units.
