MOUNTING THE PHOTOSENSOR

In most applications, the unit is mounted through a ceiling tile, with only the lens being visible from inside the room; the remainder of 

the unit rests on top of the tile. It can also be mounted on or through the wall of a skylight light well. In these types of applications, an 

accessory plastic mounting bracket is required. An accessory for mounting the unit to a J-Box is also available. The device has an 

adjustable head to accommodate multiple mounting methods and building materials or fixture walls up to 1.25” thickness.

NOTE: 

For ceiling thickness lower than 5/8”, the LMLS-500 must be used.
