•
Multi-Tech Mode – This is the default mode of operation for the sensor. PIR
technology turns lights on in this mode; however, motion detection by either
technology will keep the lights on. If neither technology detects motion, the lights
turn off after the delayed-off time.
•
Single-Tech Mode – Only one technology is active in this mode. The technology
is selected by the dip switches. Motion detection by the selected technology - PIR
or ultrasonic - will turn on the lights as well as keep them on. When motion is not
detected, the lights will turn off after the delayed-off time.
•
Delayed-Off time – The sensor is designed to turn the lights off if no motion is
detected after a specified time. This length of time is called the delayed-off time
and is set using the timer (Black) knob on the sensor. The adapting patterns will
modify the delayed-off time to fit the parameters of each installation based on
environmental conditions and occupancy patterns.
•
Walk-through Mode – The walk-through feature is useful when a room is
momentarily occupied. With this feature, the sensor will turn the lights off shortly
after the person leaves the room.
The walk-through feature works as follows: When a person enters the room, the
lights will turn on. If the person leaves the room before the default walk-through time-
out of 2.5 minutes, the sensor will turn the lights off. If the person stays in the room
for longer than 2.5 minutes, the sensor will proceed to the standard operation.
•
LED Operation – There are two LED indicators that will flash when motion is
detected. The LED flash can be disabled using the LED disable switch setting
(refer to Table 2). Green flash indicates motion detection by ultrasonic technology.
Red flash indicates motion detection by infrared technology.

INSTALLING YOUR OCCUPANCY SENSOR
NOTE: Use check boxes when Steps are completed.

Mounting Option Diagram A
Occupancy Sensor Mounted to Wallboard Using Screws
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 Mounting Option Diagram A).
6. Class II Wiring: Connect low-Voltage wires from Power Pack to Sensor per
WIRING DIAGRAM as follows: 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 circuit breaker or fuse to Power Pack.
INSTALLATION IS COMPLETE.

DESCRIPTION
The Occupancy Sensor is a low-voltage infrared and ultrasonic sensor that works with
the LCA22xx and power pack to automatically control lighting. The sensor turns the
lights on and keeps them on whenever occupancy is detected and will turn them off
after the "delayed-off time" has expired.
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.
Listed are 2 typical installation options (A and B). Choose one that best suits your
needs. Other methods of installation may be possible but they have not been described
here. Note that the wall sensor can be wall mounted or ceiling mounted simply by
rotating the neck. This gives greater flexibility in attaining the desired coverage.
A. Wall or Ceiling Installation Using Screws (Mounting Option A):
NOTE: You may use the mounting screws, nuts and washers included, or screws
in combination with commercially available wall anchors.
1. Select location for mounting of sensor for your application
(refer to Mounting Location Diagram).
2. Make a hole in the wallboard or ceiling large enough to pass the wire
connections and wire nuts through (approximately 1" diameter).
3.
Drill holes for mounting screws using mounting base as template.
