Chamberlain WIRELESS ALERT RWV400R - Manuel (Page 3)

Troubleshooting
The Alert does not function.
Check batteries in PIR Motion Sensor. Ensure Base
Station has power. Ensure PIR Motion Sensor is
programmed to Base Station.
The Alert is not getting expected transmission
range.
Ensure Base Station antenna is vertical and keep PIR
Motion Sensor away from trees and metal objects.
Ensure Base Station is in clearest possible range of
PIR Motion Sensor. The less objects between
devices, the longer the range.
Base Station is not very loud.
Adjust the volume of speaker. An accessory such as
a low voltage doorbell, buzzer or light can be attached
to the relay switch. The accessory device will need
separate power supply.
NOTE: Output switching capacity is low voltage
(24V max, ac or dc).
Static and feedback is heard in Base Station.
PIR Motion Sensor is too close to the Base Station.
The PIR Motion Sensor is detecting motion only
part of the time.
To detect cars, it is best to mount PIR Motion Sensor
at height of car’s motor and have it between ten and
twenty feet from the road. Swivel sensor as needed.
The Alert is giving false alarms.
Check for moving tree branches or insects in sensor
window. PIR motion sensor can also be triggered by
light shining directly in sensor window, such as
reflected sunlight, or motion in front of a light source.
Base Station beeps every ten minutes.
If there are two beeps the battery is low in the Base
Station. Replace with AA Alkaline batteries or operate
it with AC Adapter. If there are three beeps the battery
is low in the PIR Motion Sensor. Replace with AA
Alkaline batteries.

Mount PIR Motion
Sensor vertically on
solid surface a few feet
off the ground and
within 1000' of Base
Station. Unit should be
able to swivel as
needed.
NOTE: Do not mount PIR Motion Sensor in direct
sunlight, near moving tree branches, or in the path of
a sprinkler system.

10' - 20'
PIR Motion Sensor Installation
Vehicle Alert Installation: For cars, the best
mounting position is about 4' high, between 10-20'
back, and angled to see the back of car after passing
the sensor.
