Overview
The GLA-LDL-PC-0-10-WL is a dual-loop photosensor that continually measures ambient light
in order to achieve the optimal balance of natural and artificial lighting in daylight harvesting
applications. By harnessing natural daylight from windows and skylights, electrical lighting can
be dimmed, reducing energy usage while maintaining a consistent light level for a more efficient
and comfortable work or living space. With an IP54 rating, the GLA-LDL-PC-0-10-WL is suitable
for indoor, outdoor and wet location applications.
In closed-loop type daylight harvesting applications, the GLA-LDL-PC-0-10-WL is installed on
the ceiling directly above the primary work area. It measures all light within a 60° cone, which
consists predominately of reflected light, acquiring the most natural approximation of perceived
changes in ambient light levels.
In open-loop type daylight harvesting applications, the GLA-LDL-PC-0-10-WL is installed on the
ceiling near a window or in the light well of a skylight, directed toward the incoming daylight and
away from any electrical lighting fixtures. The system estimates the total amount of ambient
lighting in the room according to the light level measured by the photocell.
The GLA-LDL-PC-0-10-WL includes hardware to facilitate flush or surface mounting to a
drywall or drop-tile surface. Its simple 3-wire interface allows for direct connection to a
Crestron® control system via a single Versiport I/O or analog input port, with 24 V power taken
from the Cresnet® network control bus.
NOTE: Cresnet communications requires a GLS-SIM or ZUMMESH-JBOX-SIM (both are sold
separately). Power may be taken from Cresnet bus regardless of interface method.
Connects to a GLS-SIM, ZUMMESH-JBOX-SIM, Versiport I/O, or Analog Input control port
on any Crestron control system.
Using an optional sensor integration module (GLS-SIM or ZUMMESH-JBOX-SIM for a Zūm® J-
Box, both sold separately), the GLA-LDL-PC-0-10-WL becomes a full-featured Cresnet device,
streamlining the total lighting system. Cresnet provides a simple solution for configuring and
wiring sensors as part of any complete Crestron system. The Cresnet bus is the communications
backbone for many Crestron keypads, lighting controllers, shade motors, sensors, and other
devices.

Coverage
Depending on the application, the sensor has two possible fields of view. This is set by installing
jumpers as described in the Light Level Settings section below.
① Sensor field of view when using Open Loop Control (OL)
② Sensor field of view when using Closed Loop Control (CL)
Light Level Settings
Jumpers are used to set the light level range and sensor field of view.
The following options can be set by installing jumpers in the specified locations:
A. OL: 3-300 fc (factory default)
B. OL: 30-3000 fc
C. OL: 60-6000 fc
D. CL: 3-300 fc
