SETUP
Network Wiring
®
When wiring the Cresnet network, consider the following:
• Use Crestron Certified Wire.
• Use Crestron power supplies for Crestron equipment.
• Provide sufficient power to the system.
Preparing and Connecting Wires
Strip the ends of the wires approximately 1/2 inch (13 mm). Use care to avoid nicking the
conductors. Twist together the ends of the wires that share a connection and tin the
twisted connection. Apply solder only to the ends of the twisted wires. Avoid tinning too
far up the wires or the end becomes brittle. The label on the rear of the dimmer contains
a gauge for wire stripping.
Light Level Testing
Before installing the photocell, verify the daylight levels on a sunny day at the proposed
location of the photocell. With the lights switched off, use a light meter to read the daylight
level. Orient the light meter in the same direction the photocell will view. The light levels
under sunny conditions must be at least 35 fc. If the light levels are less, you should select
another location or reorient the photocell

DESCRIPTION
The GLS-LOL is a low voltage photocell which senses light levels and sends this data to
an interface device such as the GLS-SIM (sold seperately) connected to the Crestron
control system.

Photocell Placement
The photocell is designed for mounting in a dry location that is exposed to daylight. The
photocell should not be exposed to direct illumination from an electric light source. The
following illustration shows the GLS-LOL field of view.

Where windows are the primary source of daylight, the photocell typically mounts on the
ceiling between the window and the first row of fixtures. (Refer to the following illustration.)
The photocell points toward the window.

For skylight applications, the photocell mounts in the lightwell of the skylight and should be
oriented toward the incoming daylight. Typically, the photocell is aimed toward the skylight.
The light level range adjustment jumper may need to be changed to 60-6000 fc for skylight
applications.
INSTALLATION
Wiring and Testing
NOTE: Use CRESNET-P/-NP cables only. Maximum distance is 250 feet (76 m).
1. To access the GLS-LOL wiring terminals, insert a small, flat blade screwdriver into a slot
on the housing and separate the base from the lens assembly.
2. Review the "Mounting" section on the next page to determine how the cable to the
controller will enter the photocell housing. Modify either the lens housing or the base as
instructed in step 2A or 2B.
3. Connect wiring to the control system as shown in the illustrations on the following page.
(If flush mounting, feed the cable through the base before terminating.)
4. Make sure the footcandle range jumper is in the correct position for the expected light
level. (Refer to "Range Adjustment" on the following page.)
5. Attach the base to the lens assembly.
A. Align the arrow and sun icon inside the base with the lens.
B. Use gentle pressure to snap the parts together.
6. Turn on the control sytem. Verify the photocell wiring by reading the control system
display. As you cover and uncover the photocell, the reading should change. The
control system reading shows the minimum value of the programmed range if the light
level is below the range, or if the photocell is not properly connected.
