Installing Batteries
1. Remove AA batteries from their packaging.
2. Install batteries in the battery holder on the sensor making sure to orient them
according to the +/- symbols on the holder. Install provided battery clips.
3. Lock sensor to the back plate. Installation is the opposite of removal.
4. The sensor is now on and ready to be discovered.
NOTE: There is no on/off switch in the sensor. To power off the sensor, remove the batteries
from unit.
To turn on the ED Indicators
1. Twist open the sensor from the mounting plate.
2. Move the LED switch to the right to turn on the LED indicators.
NOTE: Turning switch to on will cause increase current draw to the batteries and will
shorten life based on the amount of motion detection.
3. Twist close the sensor back on to the mounting plate.

Sensor Notifications: NOTE there are only 1 led of each color. Below is for clarity
One green blinking LED1 Motion means motion has been
detected and indicates a battery voltage of more than
2.7V.
Green LED1 Motion blinking twice in a second means sensor
is looking for a network to join and battery voltage is more
than 2.7V. Sensor will double green blink while looking for a
network for 30 minutes and then stop. ress the join button
for 5 seconds to start a new 30 minute search.
A single red LED3 Low Bat flash indicates motion detected
and low battery voltage below 2.7 Volts. Battery needs to be
replaced.
Only replace batteries with same size and type.
____________________________________________________________________________________
Red LED3 Low Bat blinking twice in a second means sensor
is looking for a network and battery voltage is under 2.7V.

Commissioning
NOTE: In order to confirm proper location it is advised to mount the sensor before discovering
it.
Adding Sensor to Gateway
1. When the green LED blinks twice a second on the sensor, the sensor is ready to be
discovered/commissioned.
2. Use a Dialight gateway to discover the sensor. ( lease refer to the gateway owner’s
manual for further instructions under the devices page.)
3. Once the sensor has been added to the gateway, the green LED will stop blinking at
the rate of twice a second. You have now connected the sensor to the gateway.
4. The green LED will then blink when motion is detected.
NOTE: There is a 90 second ideal mode after a trigger detection. Thus quick repeating
will not trigger additional events.
See the Gateway manual for setting up the sensor
Removing the Sensor from a Gateway
Due to failure or relocation
1. Go to the sensor and open it and hold the SW3 Leave button for 5 seconds
2. Sensor LED’s should now be double blinking
3. Check the gateway’s GUI to verify sensor was removed from device list. ( lease refer to
your gateway owner’s manual for further instructions.)
4. Your sensor is now ready to be added to another gateway.

Troubleshooting
Sensor is not discovered by the gateway.
NOTE: This section requires the Dialight Gateway and to be connected to a computer
using the GUI interface.
Steps to solve:
1. On the gateway web page verify that discovery is turned on.
2. Follow the provided instructions to turn the internal LED switch to ON.
3. Check the condition of the LED lights through the front lens of the sensor.
4. If the red LED is blinking then the batteries need to be replaced.
5. If the green LED is double blinking then the sensor is still trying to join a network, then:
a. Verify that it is within 100 ft. of a light that has already joined the network.
b. Verify the lights are powered by commanding them to turn on from the web
page.
c. Replace the sensor.
6. If the green LED is not blinking at all then:
d. Remove both batteries.
e. Replace the batteries, verifying correct orientation.
f. When plugging in the second battery, if the red and green LED’s do not come
on for 2 seconds, then:
i. Try new batteries.
ii. Replace the sensor.

Troubleshooting Continued:
g. After plugging in the second battery watch the behavior of the green LED. If the
green LED double blinks then this sensor will try to join a network for 30 minutes. If
the red LED is blinking then replace the batteries.
h. If the Green LED is not blinking then it has already joined a network, possibly a
different network than the desired network. Hold the leave button for 5 seconds
to make the sensor leave the network. It will then double green blink and be
ready to join a new network.
Motion at the sensor does not turn on any lights.
Steps to solve:
1. Verify that motion at the sensor blinks the green LED once. If you don’t see it blink once
then wait 90 seconds and try again as the sensor has a 90 second blackout time in
which motion cannot be re-triggered.
a. If the sensor blinks green once then it is operating correctly. Continue with step
2.
b. If the sensor blinks red once then replace the batteries.
c. If the sensor does not blink at all then open the sensor and press the reset
button.
d. If the green and red LEDs do not light for two seconds then verify the batteries
are installed with the correct orientation. If they were correct then replace the
batteries.
e. If the green and red LED do light for two seconds then observe the behavior of
the green LED.
f. If the green or red LED is double blinking then this sensor is not joined to a
network. Go to the system control and discover it.
g. If there is no double blinking then the sensor is joined to a network. Try trigger
motion and see if the green led blinks once.
h. If it blinks for motion then the sensor is working correctly.
Continue to step 2.
i. If it does not blink for motion.
j. Confirm the led SW2 is set to on.
k. If not then replace the sensor

Troubleshooting Continued:
2. On the gateway web page verify that the sensor in question is assigned to a group and
that a motion event is currently ON in the schedule (see gateway manual).
3. On the gateway web page verify that the nodes in the network show with no
connection errors (consult gateway manual).
4. Follow the provided instructions to turn the sensor LED switch to ON.
5. Check the condition of the LED lights through the front lens of the sensor.
6. If the red LED is blinking then the batteries need to be replaced.
7. If the green LED is double blinking then the sensor is trying to join a network. Follow steps
in the gateway manual to discover the sensor and see if the problem persists.
8. From your gateway’s wireless devices page, display the motion sensors (consult the
gateway manual for instructions).
9. Wait until no motion sensor in the network is showing motion present.
10.Trigger motion on the sensor in question.
11.If the green LED behind the front lens of the sensor does not blink once then:
a. Try new batteries.
b. Replace the sensor.
12.If the green LED does blink then verify that one sensor on the gateway web page shows
motion present for a relatively short period of time.
13.If motion is shown on one sensor node then verify that that sensor is assigned to global
mode or the group that you want to light up.
14.If none show motion present then this sensor is likely part of a different gateway
network. Follow steps in this manual to remove the sensor from a different gateway.
