Regress lay-in (RG) drywall coffer installations

Applies when spec code "RG" is used for the mounting option. Fixtures are laid into a site-built drywall coffer, similar to lay-in ceiling tiles, resting on perimeter supports with no load-bearing mounting kit. The included grid clips are not load-bearing here; their attachment points accept hanger wire so each fixture can be tethered to the structure above to prevent it from falling into the room during seismic activity, while staying removable from below. These pages cover the required overhead clearance, the coffer construction and sizing, and the installation steps; wiring and controls are covered in the standard sections of this manual.

Regress lay-in (RG): clearance for the lay-in rotation

The fixture housing is wider than the window opening, so it only passes through the coffer tilted. It threads up through the window at a steep roll, then levels out while its lower edge stays dipped in the opening, sliding sideways over the ceiling as it flattens. The matrix below gives the minimum clearance between the finished ceiling and the structure above for this maneuver, including a 1" working margin. It assumes open plenum space beside the coffer; deeper coffers need more room almost inch for inch. Thread fixtures through a multi-cell opening lengthwise (insert the last two fixtures together before sliding the second-to-last into its cell).

Fixture size	Housing cross-section	Window opening	2×4 + 5/8″ drywall (4-1/8″ regress)	2×6 + 5/8″ drywall (6-1/8″ regress)	2×12 + 5/8″ drywall (11-7/8″ regress)
CS14 / CS154 / CS24 side by side	46-7/8″ × 3-5/16″	43-3/4″	≥ 9″	≥ 11″	≥ 16-3/4″
CS22 · CS24 end to end · CS12 side by side	23-1/4″ × 3-5/16″	20-1/8″	≥ 9-1/2″	≥ 11-1/2″	≥ 17-1/4″
CS154 end to end	17-1/4″ × 3-5/16″	14-1/8″	≥ 9-1/2″	≥ 11-1/2″	≥ 17-1/4″
CS12 / CS14 end to end	11-1/4″ × 3-5/16″	8-1/8″	≥ 10″	≥ 12″	≥ 17-3/4″

Clearance is measured from the finished ceiling face to the underside of the structure above. Rule of thumb: regress depth plus about 6". Use the interactive simulation on the next page to scrub through the maneuver; the worst-case drawings show the binding position for each size.

Fixture dimensions

Fixture size	Visible glass (W × L)	Overall including trim (W × L)
CS12 (1×2 ft)	8.33″ × 20.14″	11.93″ × 23.74″
CS14 (1×4 ft)	8.33″ × 43.76″	11.93″ × 47.36″
CS154 (1.5×4 ft)	14.12″ × 44.12″	17.72″ × 47.72″
CS22 (2×2 ft)	20.14″ × 20.14″	23.74″ × 23.74″
CS24 (2×4 ft)	20.14″ × 43.76″	23.74″ × 47.36″

Trim is 1.80" wide on all sides and overlaps a ceiling cut-out by up to 0.26" per side; housing depth is 3.60" (3.68" minimum recess including the rear screw heads). When tiling multiple fixtures, allow an additional 1/16" margin between adjacent trims. Dimensions per the Circadian Sky Dimensional Drawings (all sizes).

Typical materials

Drywall: e.g. 5/8" gypsum board
Well liner: e.g. 1/2" gypsum board on the reveal walls, finished flat white to match the trim
Framing: e.g. 2" × 4" lumber
Perimeter support: e.g. Simpson Strong-Tie 25-ft 16-gauge galvanized steel coiled strap, wood to wood, model CS16-R (Lowe's item #1944384)

Coffer sizing for every fixture size

The six-CS12 array in the figures is a worked example; the same detail applies to every Circadian Sky size. Housing depth is 3-5/16" for all sizes. The window opening is the finished glass-flush slot; butted fixtures share one continuous slot that spans from glass to glass across the butt joints (the six-CS12 example's group window is 140-5/8" × 8-1/8"). Where the well walls are lined with drywall, frame the rough opening larger by twice the liner thickness so the finished opening still matches these values. The Circadian Lab previews compute the slot for any array automatically.

Fixture size	Housing (W × L)	Window opening (W × L)	Weight	Min clearance, end to end*	Min clearance, side by side*
CS12 (1×2 ft)	11-1/4″ × 23-1/4″	8-1/8″ × 20-1/8″	7.3 lbs	≥ 10″	≥ 9-1/2″
CS14 (1×4 ft)	11-1/4″ × 47-1/4″	8-1/8″ × 44-1/8″	25.1 lbs	≥ 10″	≥ 9″
CS154 (1.5×4 ft)	17-1/4″ × 47-1/4″	14-1/8″ × 44-1/8″	33.7 lbs	≥ 9-1/2″	≥ 9″
CS22 (2×2 ft)	23-1/4″ × 23-1/4″	20-1/8″ × 20-1/8″	24 lbs	≥ 9-1/2″	≥ 9-1/2″
CS24 (2×4 ft)	23-1/4″ × 47-1/4″	20-1/8″ × 44-1/8″	43.7 lbs	≥ 9-1/2″	≥ 9″

* Overhead clearance for the lay-in rotation at the 4-1/8" example regress, by array orientation: end to end puts the short housing side across the slot, side by side the long side (a wider crossing dimension rolls less, so it needs slightly less height). For deeper regress values see the clearance matrix.

Regress lay-in (RG): installation steps

Installation steps

Prepare the drywall coffered ceiling: confirm the framing safely supports the full array weight plus drywall, the finished drywall is straight and level along the coffer, perimeter support is installed around the opening, and overhead clearance meets the clearance matrix. Line the well walls (the vertical reveal between the finished ceiling and the fixture) with drywall, primed with a stain-blocking primer and finished flat white to match the trim. Frame the rough opening larger than the finished window opening by twice the liner thickness (e.g. 1" wider each way for 1/2" board) so the finished opening still meets the clearance matrix. Finish the coffer edges with a sharp drywall corner bead (e.g. Trim-Tex RJ10LP or similar) for a crisp shadow line.
Pull power and control wiring to the fixture locations (see the wiring section of this manual).
Lay in each fixture, similar to a lay-in ceiling tile, by angling it through the coffer opening as shown in the worst-case drawings and the interactive simulation. Thread fixtures through a multi-cell opening lengthwise; insert the last two fixtures together before sliding the second-to-last into its cell.
Move each fixture into its final position resting on the perimeter support, then connect power and controls.
If hanger wire is required (so the fixture cannot fall into the room during seismic activity): before laying the fixture in, attach the wire from the grid-clip attachment points to the structure above with plenty of slack. Once the fixture is in position, push it upward into the cavity to open hand access above the housing and tighten the hanger wire, then lower it back onto the perimeter support.

To remove a fixture later: push it up into the cavity, loosen the hanger wire, then rotate the fixture back out of the ceiling the same way it was laid in.

Grid clips screwed to the back of the fixture with the provided self-tapping screws — Grid clips screw to the back of the fixture (self-tapping screws provided); their slots take the hanger wire.

Surface mount installations

Surface Mount Kit supplied when spec code "SM" is used for mounting option.

⚠ Safety Note: Gloves are recommended when handling the surface mount kit as edges may be sharp.

Step 1: Locate and Mark Studs

For remodeling/retrofit, use a stud finder to locate and mark studs. Mark and measure actual on-center stud spacings (OC). Typical spacing is 16" O.C.

Stud Finder: Use a quality stud finder to locate wood joists behind drywall. Mark both edges of each stud to ensure accurate centering of screws.

Step 2: Cut and Mount Plywood Backing Plate

Note: Plywood backing plate and mounting hardware supplied by others.

Equipment and Parts:
• ≥4x Wood screws (#12 x 2" Phillips Pan Head Wood Screws, e.g., Homedepot #802572 or Lowes #57385)
• 4x 1/4-in 1-in Self-Drilling wood screws (e.g., Strong-Tie, Homedepot, Lowes #SDS25112-R25)

Steps:
1) Cut a 3/8" thick plywood back plate to suit the fixture size (see table below).
2) Mounting holes can be with 1/4" screws or bolts. 1/4"-20 Machine screws and wood insert nuts can be used if junction box requires frequent inspections as wood screw holes can be damaged over time. Self-drilling wood screws are faster.
3) Pilot holes into wood are not required for mounting holes if using self-drilling wood screws. However, drilling through drywall with a 1/4" is recommended to avoid lifting.

Fixture size	Backing plate minimum size			Mounting holes
	Length(L)	Width(W)	Thickness	X	Y	Drill bit
1x2	23"-1/2	5"	3/8"	3.74" (95mm)	22.05" (560mm)	23/64"
1x4	47"	5"	3/8"	3.74" (95mm)	45.67" (1160mm)	23/64"
2x2	23"-1/4	17"	3/8"	15"-3/4 (400mm)	22.05" (560mm)	23/64"
1.5x4	47"	5"	3/8"	3.74" (95mm)	45.67" (1160mm)	23/64"
2x4	47"	17"	3/8"	15"-3/4 (400mm)	45.67" (1160mm)	23/64"

Note: Only 3/8" plywood is recommended for the backing plate. 1/4", 1/2", and 3/4" thicknesses are NOT suitable.

Surface mount installations (continued)

Step 3: Mount Fixture and Close Trim

Mount the fixture to the plywood backing plate using the 4 mounting holes at the corners. Once secured, close the front trim to complete the installation.

Note: Use 4 screws at the corner mounting holes. Select appropriate fasteners for your backing plate (wood screws, machine screws with nuts, etc.).

WIRING

IMPORTANT: READ ALL INSTRUCTIONS THOROUGHLY PRIOR TO INSTALLATION, USE QUALIFIED INSTALLERS/ELECTRICIANS, COMPLY WITH LOCAL ELECTRICAL CODES, RETAIN INSTALL MANUAL FOR REFERENCE.

Open Trim

Pull open the snap-fit trim

Break 1/2" K.O. (Knock-Outs)

Normal Power (All fixtures inc. Casambi)

Using WAGO 221 Connectors: Lever-actuated connectors for tool-free wire splicing. To connect: Lift the orange lever, insert stripped wire (strip ~11mm / ⁷⁄₁₆"), then push lever down to lock. Clear housing allows visual confirmation of proper insertion.

Dual Channel 0-10V (Primary fixture-only)

Both GND terminals are shared — if your dimmer has only 3 wires, one GND connection is sufficient.

DMX Tunable Sky (Primary fixture-only)

DALI-2 DT8 Tc Tunable Sky (Primary fixture-only)

Only Primary fixture have lighting control/dimming pigtails.
Only 1no. Primary is sold per group/zone
Casambi Primary fixture are wireless and does not require additional dimming wiring.
Building wires to be 18-12 AWG when using the supplied Wago connectors.

Mounting Holes & Wiring Connections

⚠ IMPORTANT: Only use the existing mounting holes to secure the fixture. DO NOT drill additional holes — LEDs and circuit boards are located along the edges and drilling may cause permanent damage to the fixture.

Mounting Points

Use the 4 pre-drilled mounting holes at the corners to secure the fixture
Use appropriate fasteners for your ceiling type (wood screws, toggle bolts, etc.)
GC and RG installations: the mounting holes are not needed — the fixture lays onto the grid (GC) or rests on the coffer's perimeter support (RG)

Wiring Connections

Power input: Connect line voltage (120V/277V) to the AC/DC power supply
Ground: Connect building ground wire to the green ground screw
Control signals: Connect dimming wires (0-10V, DMX, or DALI) to the daughter board as applicable. 0-10V board terminals are labeled DIM, CCT, and GND.
Use the supplied Wago connectors for secure connections

Remote power supply installation

The 24 VDC power supply (PSU) ships integrated to the fixture by default. When spec code "REM"is selected, the PSU is shipped uninstalled so it can be mounted remotely (e.g. above the ceiling plenum, on a junction box, or in an accessible service area). Innerscene uses Mean Well SLD-50-24 (35–45 W fixtures) or SLD-80-24 (75 W fixtures) — both have the same terminal layout described below.

⚠ Voltage drop limit: The DC cable run from the remote PSU output to the fixture's internal controller board must not exceed 0.5 V drop at full load. Voltage drop above this threshold can cause dimming inconsistency, color shift, or controller brown-out.

Recommended cable AWG vs. one-way distance

Maximum one-way cable length per AWG that keeps round-trip voltage drop ≤ 0.5 V on the 24 VDC bus. Use stranded copper, twisted pair recommended. Values calculated at 25 °C — derate for higher ambient.

Fixture	Load @ 24 V	18 AWG	16 AWG	14 AWG	12 AWG	10 AWG
1×2 (35 W)	1.46 A	26 ft (8.0 m)	42 ft (12.8 m)	67 ft (20.4 m)	107 ft (32.6 m)	171 ft (52.1 m)
2×2 / 1×4 / 1.5×4 (45 W)	1.88 A	20 ft (6.2 m)	33 ft (10.0 m)	52 ft (15.9 m)	83 ft (25.3 m)	132 ft (40.3 m)
2×4 (75 W)	3.13 A	12 ft (3.8 m)	19 ft (6.0 m)	31 ft (9.6 m)	50 ft (15.2 m)	80 ft (24.3 m)

Remote power supply installation (continued)

Installation steps

Mount the PSU enclosure in an accessible, dry location with adequate airflow. Secure per local code; orient with vents unobstructed.
Wire line-voltage AC input (110–277 VAC) to the PSU per the markings on the unit. Bond ground.
Run the 24 VDC output from the PSU to the fixture's controller board. Size the conductors per the table above. Connect red wire to VIN and black wire to GND on the controller board.
Use the supplied WAGO 221 connectors (or equivalent UL-listed connectors rated for the conductor size) at the fixture end.
After power-up, verify ≥ 23.5 V at the controller board input terminals at full output.

⚠ Polarity is critical: Reversing the 24 VDC connections will damage the controller board and is not covered by warranty. Always verify red → VIN and black → GND before applying power.

⚠ Wireless Group Installation

Unlike typical fixtures that each require individual control wiring, Innerscene uses wireless groups to reduce installation cost and ensure perfect synchronization. Each group has one Primary fixture (with control wiring) that wirelessly coordinates all Secondary fixtures in the group—eliminating voltage drop issues and ensuring all fixtures match brightness and color exactly.

Each wireless group is typically controlled by one wall dimmer. The dimmer connects to the Primary fixture, which wirelessly controls all Secondary fixtures in that group:

━━ Wired connection┄┄┄ Wireless (~50ft range)

Installation Steps

1

Sort by Group:Group all boxes with the same Wireless Group number

2

Install Together:All fixtures in a group go in the same room/area

3

Stay in Range:Keep Secondary fixtures within ~50ft of Primary

4

Wire Primary Only:Connect control wiring to Primary; Secondary needs power only

5

Test:Verify all fixtures in a group dim and change color together

Wireless Star Network

⚠ Avoid These Mistakes

Installing different groups in same area
Missing Primary fixture in a group
Fixtures beyond 50ft from Primary

Commissioning

Factory Pre-Commissioning

When ordering Circadian Sky fixtures from Innerscene with factory pre-commissioning, the local time and geolocation will be saved into the Primary fixture. The Primary fixture contains a non-rechargeable battery that will maintain the clock for around 10 years (or indefinitely if power to the fixture is maintained and dimming is used to turn off the fixture).

Primary vs Secondary Fixtures: The Primary fixture is the only fixture to require hard-wired control signals (unless using Casambi Controls). It will automatically send out dimming and colour control signals wirelessly to nearby Secondary fixtures within the same zone.

Programming Codes

The programming code in your spec determines the default behavior:

Code	Default Behavior
P0000	External Control Only — Fixture will only respond to external dimming signals (0-10V, DMX, DALI, or Casambi). No built-in schedule.
P0001	Wall-Clock Schedule (8am-6pm) — Fixture uses built-in wall-clock schedule when powered on. Time zone is based on delivery address. Daylight savings adjustments applied automatically. Exits schedule mode when external control signal changes.
P0002	Sunrise/Sunset Schedule — Fixture uses built-in sunrise/sunset schedule when powered on. Longitude and latitude for calculations based on delivery address.
Custom	Custom programming codes can be created using Innerscene's Programming Tool and will be pre-loaded before shipping.

Note: For P0001 and P0002, external dimmer signals are ignored for the first second after power on. If external control changes after this, the automated schedule will be overridden.

On-Site Schedule Configuration

To update the schedule on-site, connect to the fixture's WiFi network (e.g., Innerscene-0-10V-XXXX or Innerscene-cas-XXXX) using password "innerscene", then navigate to 172.30.0.1 in a web browser to access the configuration interface.
