Safety

• Fixture installation should be performed in accordance with local and national codes. All fixtures must be
properly grounded.

• To prevent fire or electric shock, do not expose the fixtures to water or moisture. Stealth-T fixtures are listed for
indoor use only.

• Do not attempt to dim a non-dim fixture. Do not attempt to operate a fixture without lamps installed, as this
could damage the ballast.

• Do not attempt to change the lamps on a fixture that is energized, or to work with your hands near an exposed
socket that is energized.

• A qualified technician should perform service on fixtures. Do not remove the ballast cover until the unit has
been de-energized.

• Brightline fixtures are not Insulated Ceiling (IC) rated. Maintain the proper distance from insulation.

• In case of lamp failure:

1. Turn the fixture power off.

2. Wait 30 seconds for the ballast to reset.

3. Install the new lamp(s).

4. Turn the fixture back on.

Installation

1. Unpack the fixtures. The louver frames and lamps may be packed with the fixtures or separately.

To prevent damage, install the fixtures before installing lamps and louver frames.

2. Prepare the line-voltage wiring to the fixtures. Depending on building conditions, it may be necessary

to install the power and control wiring before the fixture is placed in the ceiling. Ensure that the supply
voltage matches that required by the ballasts. To install the power feed, remove the knockouts as needed
and install the correct type of power cabling and strain relief (not provided). Connect the wires from the
feed using wire nuts, observing the wire color-coding, and re-install the knockout plate. Brightline
fixtures intended for the North American market use Black/White/Green wires respectively for
Line/Neutral/Earth Ground; fixtures shipped to other locations use Brown/Blue/Green-Yellow for
Line/Neutral/Earth Ground. You may want to install sufficient slack in the power cable so that, if
necessary, the fixture can be moved to an adjacent ceiling opening.

3. These fixtures are not Insulated Ceiling (IC) rated. Maintain the proper distance from insulation

(3 in [76 mm] in the US and Canada).

4. If the fixture requires low-voltage control, the proper wiring must be run to each fixture. Connect the

control wires inside the fixture, observing the proper color-coding. Install the control wiring
above the ceiling. (See the Control Wiring section below.)

5. Fixtures can be mounted in two ways: either flush-mount in a “hard” ceiling, such as plaster or drywall;

or mounted in a T-Grid acoustical-tile ceiling.

• Hard Ceilings: Verify that the locations in which you

intend to mount the fixtures are free of above-ceiling
obstructions such as ceiling joists, air conditioning
ducts, etc. For ease of installation, a minimum of
8 in [203 mm] of clear height above the ceiling is
recommended. In accordance with drawings provided
by Brightline or the local architect or engineer, prepare
the ceiling by cutting openings that are 24.56- x 24.56-in
[624- x 624-mm] in size. Depending on ceiling construction,
it may be necessary to install a frame in the opening to
accommodate the weight of the fixture. Install the power and
control wiring as described above. With the mounting clips
in their recessed position (folded back next to the fixture,
see figure 1), lift the fixture into its opening.

Figure 1

Using a screwdriver, turn the screws on the bottom of the mounting clips until the clips turn approximately
90° and rest on the frame or ceiling structure. (Figure 2) Adjust the clips so the bottom of the fixture is
flush with the exposed side of the ceiling. (Figure 3)

Installation

5. (continued)

• T-Grid Ceilings: Prepare the T-Grid to receive the fixtures. Fixtures are available for either 2- x 2-ft or
600- x 600-mm grid spacings. Depending on the ceiling layout, it may be necessary to add additional track
sections and/or prepare different sized ceiling tiles. For ease of installation, a minimum of 8 in (200 mm)
of clear height above the track is recommended. Make sure that the T-Grid is sufficiently braced to accept
the weight of the fixtures. Place the fixtures into the correct openings in the ceiling grid in accordance with
plans provided by Brightline or the local architect or engineer. If required by local code, install “safety clips”
to attach the fixtures to the T-Grid or the building structure.

5A. Install “safety wires” on the tabs on the sides of the fixtures and attach to the building structure,
in compliance with local codes. (Figures 4 and 5) Brightline recommends not relying on the t-track
alone to hold the weight of the fixtures.

Figure 5Figure 4

Note: Use screwdriver to bend tabs outward to install safety wires.

6. If necessary, complete the installation of the power and control wiring

7. With the power off, install the lamps. Make sure they are firmly seated in their sockets and clips.

8. Energize the fixtures and test for proper operation.

8. Energize the fixtures and test for proper operation.

9. Install the door frame and louver assembly, with the openings in the louvers pointed in the correct
direction(s) as indicated on the project drawings. (Figure 6 and 7)

10. For optimal performance, Season lamps for 12 hours prior to dimming.
Note: Approximate initial Lumens after 100 hours of operation.

1. Untighten self-tapping screw

2. Remove bracket from fixture enough to
access terminal block

3. Feed leads through the grommetted hole

4. Wire according to label adjacent to
terminal block. Tighten contact screws

DALI Dimmed

A

DALI (Digital Addressable Lighting Interface) signal controls these fixtures. The fixtures will function (but not dim) in

the absence of a control signal.

The control signal is connected to the fixture through the 3-pin XLR-type receptacle on the side of the unit. As this is
low-voltage wiring, it may not be necessary to install the control wiring conduit. If they were specified, the DALI
control cables may be provided as part of your order. Two receptacles are provided to allow the control wiring to be
daisy-chained.

As each fixture is assigned an individual address, fixtures on a DALI control line may be dimmed to differing
intensities.

DALI control wiring is topology and polarity independant. DALI control cables may be daisy chainned. Keep the total
wire run as short as possible. See the literature that is provided with your DALI controller, or contact Brightline for details.

Power for the DALI network is provided by a seperate power supply. See the instructions that come with it for
installtion instructions.

For clarity, only one fixture’s power feed is shown. Each fixture requires a source of unswitched AC power.

the supplied WinDIM software. The BusMaster may optionally be controlled by an A/V proccessor via its RS-232
serial interface.

Maintenance

• The fluorescent lamps provided with the fixtures are rated for up to 10,000 hours. However, as with all
lamps, there will be some drop-off in intensity as they approach their rated life. A conservative user may
want to re-lamp at 75-80% of the rated life. Brightline recommends that as lamp intensity begins to
drop off, or when the life expectancy is reached, all lamps in a room be replaced as a group.

• The lamps provided with your Brightline fixture have been selected to provide the correct operating
parameters for your video system. All lamps should be replaced with those having an identical model
number and manufacturer. After relamping, it may be necessary to perform a new white-balance on your
camera(s) after re-lamping. Contact your Brightline dealer or representative if you need assistance
in purchasing replacement lamps.

• Dispose of used fluorescent lamps in conformance with local regulations or by participating in Brightline’s
lamp-recycling program.

• For optimal fixture performance, it is necessary to keep the lamps and lenses clean. Use a dry, non-abrasive
cloth to remove dust. Avoid the use of materials that might scratch the lenses.
