LEDALITE ID-39 TruGroove T-Grid Ceiling System
Installation Instructions
Standalone or Continuous Run in T-Grid Ceiling
These instructions review how to install TruGroove recessed fixtures in T-Grid ceilings. Please refer to layout drawings supplied by Ledalite in conjunction with these installation instructions. The graphics below show the components required.
- Hanger Kit 390ZK01
- **Joint Kit 390JK01***
- Joint Kit 390JK03
Note One kit is required for each joint. Joint kit type is determined by flush or regressed lens mounting and symmetric or asymmetric light distribution. Tools: Phillips screwdriver, 5/16” Nut Driver
ATTENTION: Install in accordance with local and national building and electric codes. This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense.
Important Notes
Warning, Shock Hazard
The fixture must be connected to the building ground via the provided ground wire before connecting to the mains power supply. Disconnect or turn off the power before attempting any installation, service, or maintenance.
Prepare Fixtures
Arrange boxed fixtures on floor in specified mounting locations, based on supplied layout drawings. Remove fixtures from boxes. Remove plastic from fixtures. Match up each fixture and lens based on the spec tag and ID number labeled on each fixture box for the specified run.
T-Grid
Install main T’s, 4” on center. For continuous row lengths, refer to supplied layout drawings. Add 1/4 “ to the overall housing length indicated on your layout drawings. Position the cross T.
Install Fixtures
Install Mounting Brackets
Important: Install T-Grid mounting brackets to the required height.
Install Fixture Above T-Bar Grid
Install the first fixture (or Standalone Unit)from above the T-Bar Grid.
ATTENTION: Install in accordance with local and national building and electric codes.
NOTE: For Standalone fixtures skip to step 7
Install Joiner Aligners
Important: To insert aligners, tap gently with a hammer until half is inserted into the joiner channel. Be sure to engage the dimple.
Complete Wiring and Connect Fixtures
Install the joiner fixture into the T-Bar Grid from above. Complete wiring and slide the fixtures together.
Install Joiner Brackets
Important: Hand tightens bracket screws while supporting the housing on the opposite side. Gradually alternate side while tightening. Do not over- tighten.
Secure the Fixture
Secure the fixture hanger brackets to the TBar grid. For continuous runs, finish installing run first and then secure to the T-Bar grid.
Install Power Drop
Install power drop at the desired location. At the power location(s), remove factory installed wire cover. Feed power wires through Complete all wiring connections.
Re-install Wire Cover
Re-install wire cover and slide to lock. Install screw.
ATTENTION: Install in accordance with local and national building and electric codes.
Install Seismic Restraints
Install seismic restraints according to to local building code requirements.
Secure Joint Cover Flush lens and Symmetric
At joint location(s), secure joint covers using Philips screwdriver and supplied hardware. Ensure cover plates sit flush with bottom reflectors for proper LED board fit
Secure Joint Cove 11b Regressed lens or Asymmetric
At joint location(s), secure joint covers using Philips screwdriver and supplied hardware. Ensure cover plates sit flush with bottom reflectors for proper LED board fit.
Flush Lens Installation and Removal
Flush Lens: Snap in the lens into the fixture.
Lens Removal: To remove the snap-on lens for maintenance purposes, insert
a flat, smooth-edged object between the lens and housing. Twist to release
pressure and remove the lens.
Regressed Lens Installation
Regressed Lens: Angle lens to insert into the fixture. Lay lens on aluminum extrusion flange. Ensure lens engages between lens retaining clips to prevent movement of lens.
NOTE: Please refer to the layout drawing and match up each lens based on the ID number.
ATTENTION: Install in accordance with local and national building and electric codes.
Sensors in Rows
Single Sensor Controlling Whole Row
Purple & brown (or purple & grey/pink) control wires MUST be connected between fixtures.
Note:
- A maximum of 8 drivers can be wired to one sensor; confirm fixture driver count with factory.
Multiple Sensors Controlling Separate Zones in a Row
Purple & brown (or purple & grey/pink) control wires MUST NOT be connected between zones.
Notes:
- A maximum of 8 drivers can be wired to one sensor; confirm fixture driver count with factory.
- Only one sensor is allowed on a wired zone. (Sensors can be paired together wirelessly via a mobile app).
Sensor Spacing
- For correct operation, sensors should be placed a minimum distance of 8ft apart.
- Wireless sensors should be placed no further than 40ft apart for good wireless signal connection.
Important Consideration When Using Sensors in a Row
- For fixtures with wireless sensors (CS, SB or RA options):
- DO NOT connect fixture purple & brown (or purple & grey/pink) control wires to an external dimming switch. Fixture mains wiring should not be connected to a circuit with an external on/off switch.
- For best aesthetic condition, place sensors at the ends of the row only so as not to break the continuous lens.
- For better occupancy coverage in long rows, sensors may be placed mid-run, but keep in mind this will break the continuous lens into discrete sections. Alternatively, remote sensor may be used, note the same wiring rules will apply.
Occupancy Sensor Coverage
Note: Longer dimension of the detection area (Y1, Y2) is parallel to the longer dimension of the luminaire.
Daylight sensor
The light sensor measures the total amount of light in
a circular field of approximately 80% of the PIR
detection area. The following aspects should be
observed during installation:
- Minimum distance from the window ≥2ft (0.6m).
- Prevent light reflections from outside entering the sensor (for example sunlight reflection on a car hood) as this will lead to incorrect light regulation.
As a guideline, the formula 0.72 x H can be used to calculate the minimum distance between the window and sensor whereby H is the height from the bottom of the window to the sensor.
The detection area for the movement sensor can be roughly divided into two parts:
- Minor movement (person moving ≤3ft/s or 0.9m/s).
- Major movement (person moving ≥3ft/s or 0.9m/s).
