1513 Li9hting Controls. Lighting, including exempt lighting in
<br />Section 1512, shall comply with lhis sectian. Where occupancy
<br />sensors are cited, they shall have the features lisled in Sedion
<br />7513.6.1. Where auromatic time switches are cited, they shall
<br />have the features listed in Section 1513.62.
<br />151J.1 Local Control and Accessibility: Each space,
<br />enclosed by walls or ceiling•height partitions, shall be provided
<br />with lighting controls located within that space. The lighting
<br />contmis, whether one or more, shall be capable of lurning off
<br />ail lights within the space. The conirols shall be readily
<br />accessible, at the point of entry/exit, to personnel occupying or
<br />using the space.
<br />EXCEPTIONS: The following lighling conlrols may be
<br />centralized in remote locations:
<br />7. Lighting controls lor spaces which musl be used
<br />as a whole.
<br />2. Automatic controls.
<br />3. Controls requinng trained operators.
<br />4. Controls lor safety hazards and security.
<br />1513.2 Area Controls: The maximum lightiny �ower that may
<br />be controlled from a single switch or automatic conu�; �hall not
<br />exceed that which is pmvided by a Rvenly ampere circuit
<br />loaded to not more lhan eighty percent. A master control may
<br />be installed provided ihe individual switches retain their
<br />capability to function indepentlently. Circuit breakers may not
<br />be used as the sole means of switching.
<br />EXCEPTIONS:
<br />7. Industrial or manufacWring process areas, as
<br />may be required for production.
<br />2. Areas less than fve percent of footprint for
<br />footpnnts over 100.000 square feel.
<br />1513.3 Daylight Zonc Control: All daylighted zones, as
<br />defned in Chapter 2, both under overhead glazing and
<br />atljacent to verti:al giazing, shall be provided wilh individual
<br />centrols, or daylight-or occupant-sensing aulomatie eontrols.
<br />•xhich control ihe lights independenl o(general area lighting.
<br />Contiguous daylight zones ad;acent to vertical glazing are
<br />allowed to 6e controlled by a single controllinn device provided
<br />that they do not include zones facing more than rivo adjacent
<br />cardinal orientations (i.e. ncnh, east, south, west). Daylight
<br />mnes under overhead glazing more than 15 (eet from the
<br />pzrimeter shall be controlled separately (rom daylight zones
<br />adjacent to vertical glazing. ,
<br />EXCEPTION:
<br />Daylight spaces enGosed by walls or ceiling
<br />height partitions and coNaining 2 or fewer light
<br />fiMures are not required to have a separate switch for
<br />general area lighting.
<br />1513.4 Display, Exhibition, and Specialty Lighting
<br />Controls: All dispiay, exhibition, or spcciaity lighting shall be
<br />controiled independently of general area lighting.
<br />1513.5 Automalic ShubOff Controls, Exterior. Exterior
<br />lighting not intended for 24•hour continuous use shall be
<br />automatically switched by 6mer, photocell. or a combinaticn of
<br />timer and photocell. Automatic time switches must also have
<br />program back•up capabililies, which prevent the loss uf
<br />progrem and time settings for at least 10 hours, if power is
<br />interrapted.
<br />1513.6 Automat: Shut-0H Controls, Inlorior: Office
<br />bui�dinqs greater �hen 5,000 sq. fl. and all school classrocros
<br />shall Lc equipped with separate automatic controls to shut off
<br />the lighting dunng ,moccupled hours. Automatic wntrols may
<br />be an occupancy smsor, time swikh, or other device capa6le
<br />of aulomatically shu'ting oH lighting.
<br />EXCEPTIOIIS:
<br />1. Areas that must be coNinuously illuminated. or
<br />illuminattd in a manner reqwring manual
<br />operation o( the lighting.
<br />2. Emergenc, i�ghting systems.
<br />3. Switching ix industrial or manufacWring proczss
<br />facilities as may be required for proCuction.
<br />1513.6.1 Occupancy Sensors: Occupancy sensors shall oe
<br />capable of 2utomaucally turning of( all the lights in an area no
<br />more than 30 minutes aher the area has been vawted.
<br />1517.6.2 Automatic Time Swilches: Automatic time switches
<br />shall have a minimum 7 day clock and be capable of being set
<br />for 7 di(ferent day rypes per week and incorporete an automatic
<br />holiday "shut-off' feature, which turns off all loads for at least
<br />24 hours and then resumes rortnally scheduled operations
<br />Automatic time switches shall also have program back-up
<br />capabilities, which prevent the loss of program acd time
<br />seltings for at least 10 hours, if power is interrupted
<br />Automatic time switches shall incorporate an cver-r�de
<br />switching device which:
<br />a) is readily accessible;
<br />b) is located so ihat a person using the device can see th•a
<br />lights or the areas controlled by the switch, or so that the
<br />area being illuminated is annunciated�, and
<br />c) is manually opereted;
<br />d) allows the lighting to remain on for no more than two hours
<br />when an over-ride is initiated; and
<br />e) controls an area not exceeding 5,000 square feet or 5
<br />percent of fwtprint for tootprints over 100,000 square feet,
<br />whichever is grealer.
<br />1519.7 Commissioning Requirements: For lighting controls
<br />which include daylighl or occupant sensing automatic cont•ols,
<br />automatic shul-of( conlrols, occupancy sensors, or automaiic
<br />lime swiiches, lhe hghting controls shall be tested to ensure
<br />that control devices, components. equipment and systems are
<br />calibreted, adjusted and operate in aaordance with approred
<br />plans and specifications. Sequences o( ope2tion shall be
<br />(unctionally tes;ed to ensure they operate in accordance v.�th
<br />approved plans and specifcatlons. A complete report of test
<br />procedures and results shall be prepared and fded �vith the
