3. Hang the Sensor at the entrance of your driveway (such as on a mailbox, on a tree or or a
ground stake). You may also place the PIR sensor on your garage, near the front entrance or
rear door. Any movement nearby will let the PIR transmit a signal to the receiver chime unit
triggering it to sound.(Fig.3)
4. Please ensure the Sensor unit is mounted at least 5 feet above the ground.
5. The Photo Infrared Sensor will also detect heat and set off the alarm/chime. Avoid aiming the
sensor directly at sources of heat.

8. Testing the detection coverage of the Sensor.

After selected a location to install the Sensor, you can slide the FUNCTION
SELECTOR (#3) to Chime position and wait 30 seconds for the unit to adjust to the
location. Walk in front of the unit and observe the detection LED on the Sensor.
When the unit detects motion within the coverage range, the LED will light on the
Sensor, and the chime will sound on the receiver. The unit will not respond if you are
out of the coverage range. Adjust the height and placement of the Sensor to obtain the
best desired coverage.
