UL2F-EZR Module

2..

Install a ULM-EZR module in the ceiling, positioning it 6 to 10 feet from windows and over a work surface (it must be within 10 ft of a luminaire).

Using the low voltage plug-in 12' long CAT5 cables provided with the luminaires*, connect the luminaire and ULM-EZR module.

An additional CAT5 cable will be provided with each luminaire* to plug in additional luminaires* as in a daisy chain. Up to 20 luminaires* can be connected to a single ULM-EZR module.

ULM-EZR modules can be moved or added at any time merely by plugging or unplugging the CAT5 cables.

Both ULM-EZR modules and fixtures have proprietary RJ45 dual receptacles for the CAT5 cable with RJ45 plugs.

ULM-EZR module sensor placement guidelines:

Before adjusting sensor settings, check to make sure they have been installed in accordance with the following guidelines: Sensor SHOULD be located

•Between 6-10’ away from window

•Over work surfaces

Sensor should NOT be located

•Over very dark surfaces (e.g. dark carpet or furniture)

•Over highly reflective surfaces (e.g. polished floors or tables)

•Outside the daylit zone (typically beyond 15’ from window)

Ordering Guide:

When there is no daylight, place a lightmeter on the work surface and take a footcandle reading.

Adjust to desired footcandle level by rotating the sensor in the face of the ULM-EZR Module.

The sensors are factory pre-calibrated to 45fc on the horizontal, assuming standard reflectances (80/50/20), ceiling heights (8-10’) and work surfaces (2.5’).

To return to the default setting, rotate the aperture until it ‘clicks’ back into place at the mid-point.

The DL System is the combination of the ULM-EZR Module (UF2F-EZR) and a Lightolier recessed fluorescent fixture* with a 0-10 volt dimming ballast and the #EZR option. This option includes integrated RJ45 receptacles and a 12 foot long CAT5 cable.

The Module and luminaire need to be ordered separately.
