Pre-Wiring

Jellyfish Lighting Prewire / Soffit 

The intent of a prewire is to put all the wires behind the walls.  We try to achieve the following objectives. 

#1 – Wire all of our starting points to the control box. 

#2 – Wire all of our jumps between rooflines

#3 – Run data / CAT6 from the control box location to the data room / control room /  modem location. 

Materials we use

– 16/4 wire

– CAT6

There are two types of prewire 

#1 – Prewire to use now – Hanging down from facia

#2 – Prewire for future use – Coiled above facia for future use

NOTE: Traditional Aluminum vs Hardie or other type of facia soffit combination

#1 – Our goal is to drop the line into the middle of the track

#2 – The Facia / Soffit combination can influence the wire placement

#3 – See diagram at the end of this document

Where does the wire go?

– We rely on those installing the soffit to keep our wire in the most desireable spot.

– Our track runs parallel along the facia where the facia and soffit meet. 

– Our track is 1 ¼” wide.  

– Our desire is to have the wire come out of the soffit within this area as to not leave any wire or hole exposed. 

– In most cases, if the wire drops right where it is placed, it will be behind our track. (½” to ¾” from the edge where the soffit and facia meet – See examples and diagram below)

HOW THE LIGHTS LOOK INSTALLED:


 

Examples

WRONG WAY – On this example the hole in the facia where the wire exits will most likely mean a section of facia may need to be replaced. 


 

RIGHT WAY and WRONG WAY – On this example, the top wire is perfect.  Right where the soffit and facia meet. The bottom wire however, may leave an exposed hole once our tack is installed.  As the wire will need to be moved to exit under our track. 


 

RIGHT WAY – On this image, the wire is in a perfect position – This wire is about ½” to ¾” from where the soffit and facia meet.  This should fall directly behind our track. 


 

RIGHT WAY – On this example, the wire is hanging in the position we install it.   In most cases, it is tacked hanging down from the soffit, towards the end of where our track with start or stop. With a 1” lip from the facia. This wire should end up right in the center of the track.

HARDIE BOARD SOFFIT AND FACIA

  • If you are installing a hardie board facia, we need to drill a small hole into the facia board so that our line drops in the middle of the facia board.  Rather than running it down the inside edge of the board. This will ensure the line is behind the track as the track with butt-up to the hardie facia.  

 

RIGHT WAY – This is an example of a Pre-Wire for a “Hardie Board” or “Tongue and Groove” T&G Soffit.


 

WRONG WAY – In this case you can see the wire exits through a side wall, through the siding rather than the facia. 


 

WRONG WAY – And in this case, right in the center of the soffit.

LENGTH

  • Our control box will power 300 feet of lights max.  
  • At 250 feet, we typically add a power supply so the system is not run at maximum capacity. 

PLANNING A PRE-WIRE

  • We do our best to make sure the lights all run in the same direction.  
  • Starting points are the same on each roofline to ensure the lights flow in the same direction.
  • Example using the same corner of the house for a starting point. 
  • If lines must split in two directions, it is always best to do this on a corner rather than the front of the house.
