Model/Features
The Occupancy Sensor is a low-voltage infrared and ultrasonic sensor that works with the
GLS-SIM (or other compatible interface) to automatically control lighting. The exact behavior
of the sensor can be configured via software, but the sensor is typically used to turn lights on
when a room or area is occupied, and to shut them off when the room or area is vacated.
The sensor continually analyzes and adjusts to changing conditions. The sensor uses the
latest microprocessor-based technology which permits it to continually adjust and optimize its
performance. The combination of ultrasonic (doppler shift) motion detection, which gives
maximum sensitivity, and infrared motion detection, which gives higher false triggering
immunity, yields a sensor with excellent performance.
DESCRIPTION
• To be installed and/or used in accordance with appropriate electrical codes and regulations.
• If you are unsure about any part of these instructions, consult a qualified electrician.
• Sensors must be mounted on a vibration free surface.
• All sensors must be mounted at least 6 feet away from air vents.
• Do not mount sensors closer than 10 feet from each other.
• Do not touch the inner surface of the lens. Clean outer surface with a damp cloth only.
WARNINGS, CAUTIONS & NOTES
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.
NETWORK WIRING
CAUTION: Insufficient power can lead to unpredictable results or damage to the
equipment. Please use the Crestron Power Calculator to help calculate how much power
is needed for the system. (www.crestron.com/calculators).
WARNING: To avoid fire, shock, or death; turn off power at circuit breaker or fuse and
test that power is off before wiring!
NOTES: Observe the following points regarding sensor installation.
PREPARING AND CONNECTING WIRES
Strip the ends of the wires approximately 1/2”. 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.

MOUNTING LOCATION DIAGRAM
Mounting to Drop Ceiling Using
Screws, Nuts, and Washers
OPTION A. Wallboard or Drop Ceiling Installation Using Screws
NOTE: You may use the mounting screws, nuts and washers included, or screws in
combination with commercially available wall anchors.
1. Select the location for mounting of the sensor for your application. (Refer to Mounting
Location Diagram).
2. Make a hole in the wallboard or ceiling tile large enough to pass the wire connections
and wire nuts through (approximately 1" diameter).
3. Drill holes for monting screws using mounting bracket as a guide.
4. Install the mounting bracket of the wall sensor to the wallboard or ceiling using the
included screws, nuts and washers.
5. Pass wires through the base cover/neck assembly. (Refer to the suggested mounting
option illustrations below.)
6. Connect low voltage wires from the GLS-SIM or other Crestron
®
device as shown in the
wiring diagram. Twist strands of each lead tightly and, with circuit conductors, push firmly
into appropriate wire connector. Screw connectors on clockwise making sure that no
bare conductor shows below the wire connectors. Secure each connector with electrical
tape.
7. Push wire connections through the center hole of the back cover and into the wall or
ceiling.
8. Snap neck and base cover onto mounting bracket in the desired orientation.
9. Push wires through the hole and begin to fasten the plastic nut around the back of the
sensor body. Move the sensor body to the desired orientation and then continue to
tighten the nut around the sensor body.
10. Restore power at the circuit breaker or fuse. INSTALLATION IS COMPLETE.
OPTION B. Wallboard or Drop Ceiling Installation Using Back Box
OPTION C. Surface Mount Raceway Installation
Mounting to Octagon Back Box Installed Flush to Drop Ceiling
