OWL™
Microwave Motion & Infrared Presence Sensor
Instruction Manual
The OWL is a vehicle motion and presence sensor that utilizes microwave and infrared technology to
activate automatic doors and industrial gates. The OWL’s microwave sensor detects moving vehicles, while
the infrared presence sensor can detect vehicles and pedestrians. The sensor features two relay outputs,
one for vehicle motion detection, and the other for presence detection. The OWL features settings for fine-
tuning the presence detection area, direction detection, hold time, and more.
The OWL-RC remote control is required for programming and servicing the OWL.
Cautions and Warnings
Install the OWL according to instructions from the door operator manufacturer. Comply
with all applicable codes and safety regulations.
When drilling, ensure no damage can be caused in desired mounting location, e.g. hidden
wires, waterlines, etc.

Installation
1. Unscrew the Philips-head hinge screws from the left and right side. Remove the sensor from the
mounting bracket.
2. In the desired location, install the mounting bracket at a height between 11.5 and 21.3 ft (3.5 and 6.5
m). Drill 1/8” (3.5 mm) mounting holes as shown in the diagram and attach with the provided screws.
3. Re-attach the sensor to the mounting bracket using the Philips-head hinge screws from Step 1.
Adjust to the desired angle, and tighten the hinge screws until snug.

Vehicle Motion Detection
The OWL’s microwave sensor will only detect moving vehicles (cars, forklifts, etc.). When a moving vehicle
is detected, it will activate the vehicle motion output relay. If the microwave sensor is detecting people,
lower the microwave sensitivity.
The microwave sensor’s detection area may be changed by adjusting the angle of the sensor
in the bracket, changing the tilt angle of the module inside the sensor, or configuring the
microwave sensitivity setting ( ).
The microwave sensor can also be configured to ignore all cross traffic (vehicles moving parallel to the
door) and departing vehicles (see Programmable Parameters on page 7).
Presence Detection
The OWL uses a pair of 6 x 5 infrared LED arrays to detect the presence of vehicles and people.
When detection occurs, it will activate the presence output relay.
The presence output of the OWL is initially triggered by motion. The amount of motion required to trigger
presence detection is controlled by the infrared sensitivity setting ( ). The higher the setting,
the less motion required to activate the presence detection and output. Once triggered, the output will
remain on until the object(s) being detected leave the detection area, or until the configurable presence
timer has run out (at which time the presence sensor will relearn the environment).
The detection area can be changed by adjusting the angle of the sensor in the bracket, or by configuring
the infrared LED array settings. The farthest rows of the infrared LED array may be turned off sequentially.
The outside columns of the infrared LED array may be turned off in pairs on the left and right side
of the array.
The OWL’s infrared presence sensor can be set to detect vehicles only, ignoring pedestrian traffic
( ). The sensor can distinguish between the two based on the amount of light diffused.

array

Programming the OWL
1. If a security code has been programmed on the sensor, then it must be entered before settings can
be changed. Unlock the sensor by pressing the button, then entering the four-digit security code,
and press the enter button ( ).

2. To change a setting, point the end of the remote at the sensor, and press the button of the function
to be changed. The green LED on the front of the sensor will turn off, and other LEDs on the front of
the sensor will turn on.
3. Press one of the possible setting value options ( thru ). The green LED on the front of the
sensor will flash the same number of times as the setting selected.
Not all functions use thru as a valid range of setting values. Please see page 7 for
more information.
4. Press the enter button ( ). The green LED on the front of the sensor will flash four times.
Make sure there are no vehicles in the presence detection area when saving a setting.
The sensor’s infrared sensor relearns the environment when a setting is saved. If there is a
vehicle in the presence detection area while it relearns the environment, then the presence
output will lock on when the vehicle moves.
