microStar™Motion Sensor
DESCRIPTION
The microStar™is a microwave motion sensor with Human
Presence Radar™ (HPR™) for activating all types of
automatic doors. The sensor is capable of wide or narrow
detection patterns and provides a relay output for simple
interfacing with a door controller or other type of device.
INCLUDED IN THE BOX DIMENSIONS
(1) microStar™Motion Sensor
(1) Wire Harness
(2) Mounting Screws
(1) Installation Instructions
SPECIFICATIONS
MECHANICAL INSTALLATION
NOTE: Remember to follow these safety precautions:
Shut off power to the automatic door before wiring sensor.
Always ensure wiring is located clear of any moving door parts to avoid damage.
Always be aware of pedestrian traffic. Keep people clear of the work area when setting up or testing the door.
Comply with all applicable building codes and safety standards (ANSI A156.10).

①Remove the sensor cover:
Remove the cover of the microStar by placing the blade of a
small screwdriver in the notch in the right side of the cover as
shown at right. Once the sensor is attached to the header the
cover can be removed in this same manner.
② Peel and attach the self-sticking mounting
template (C) at the desired location. Drill 3
holes noted on template (1 wire passage
hole, 2 screw pilot holes).
③ Insert mounting screws partially into holes. Route the wire harness through the wire passage hole as shown. Install
the microStar onto the mounting screws and tighten.
CONFIGURATION
① Select the proper antenna orientation for the application:
② To change the orientation of the antenna, perform the following:
To remove the antenna: position index and middle fingers on the back of the PCB, position thumb on the top
edge of the sensor holder. Squeeze thumb toward fingers. Remove the sensor from holder.
Rotate antenna 90ºto change zone orientation and then re-install antenna into the holder.

WIDE

Important –When the antenna is in the narrow orientation and the wires exit at the bottom of the PCB, ensure
wires are routed under the holder and remain clear of the front of the antenna.
▪The wires must never be in the front of the antenna or improper performance may occur.
Once completed, the antenna holder can be
rotated and/or tilted to achieve proper position
of the detection field per the requirements of the
application.
② Set the dipswitches per the application:

Fail-Safe:
oWhen enabled, the fail-safe function causes the output relay to energize as soon as the sensor is
powered on. The relay will then de-energize when the sensor is activated or when there is a power loss.
In this manner, a power loss causes the relay output to perform the same as if there was a detection. If
fail-safe is disabled, the relay remains de-energized when power is applied and will only energize upon
an activation.
HPR:
oWhen the Human Presence Radar is enabled, the sensitivity of the radar is increased to allow detection
of extremely slow movements within the field of detection.
Depart/Approach:
oWhen configured for DEPART, the sensor will only detect activity that is moving away from the sensor. In
APPROACH mode, the sensor will only see activity that is approaching the sensor.
Bi-Directional / Uni-Directional:
oThe Bi-Directional function allows the sensor to see movements from all directions within its detection
zone. In Uni-Directional mode, the sensor only detects movements that are towards the sensor.
WIRING
① Wire the sensor according to the application and plug the harness into the sensor upon completion. Wire
connections are shown below.
POWER-ON
① Upon completion of the mechanical installation, configuring the sensor, and all necessary wiring, apply voltage to
the sensor (12 to 24 volts AC or DC).
The LED located at the lower left side of the antenna will illuminate green when the sensor is ready for use.

Once the sensor is ready for use, one can begin walk-testing and adjusting the lateral angle and tilt angle as
desired.
HELPFUL HINT:
To quickly adjust the pattern, press the Reset button
and then press & hold the Install button 3 seconds (the
LED will flash orange to confirm). This puts the
microStar into the install mode allowing the installer to
walk test the pattern from several different directions
without activating the door. Simply watch the LED
while approaching the pattern Green = No detection;
Red = Detection. Once the desired pattern is achieved
press the reset button and the microStar will reset to
normal operating mode.
RE-INSTALL COVER
① Replace the cover by engaging the left side first and then gently
snapping the cover into place.
② After re-installing the cover, be sure to walk-test the sensor again to
ensure there has been change in the detection zone.
