Chamberlain PIRV400R User Manual

The PIR Motion Sensor only works with 
Chamberlain's Wireless Pedestrian & Vehicle Alert
with Voice (Model RWV400R) and Office Alert
(Model CWV1000). The PIR Motion Sensor can be 
used to monitor motion up to 30' away and can 
transmit a signal up to 1000' away from the Base 
Station (not included). The Passive Infra-Red sensor 
detects movement of people and vehicles, while 
allowing small animals to pass through undetected. 
The PIR Motion Sensor has a built-in microphone and 
speaker that allows for communication between the 
Base Station and the Sensor. When the PIR Motion 
Sensor detects movement a signal is sent to the base 
station which alerts the homeowner with sounds and 
lights. The Alert can also remotely control a low 
voltage electrical device near the PIR Motion Sensor 
like a light or a camera (See Advanced Features).

Intercom Feature: When PIR Motion Sensor has 
detected motion, the Base Station will allow you to 
listen through the PIR Motion Sensor for 10 seconds. 
If you wish to talk to the person on the other end, 
hold down the Talk button and speak, releasing it to 
hear.

Volume: Pressing the Volume button repeatedly will 
cycle through volume levels.

Mute: To temporarily mute Base Station, hold the 
Volume and Talk buttons down for three seconds. 
The Base Station will reactivate after one hour, or by 
pressing the Talk button.

Battery: The AA Alkaline batteries (not provided) will 
last up to 2 years depending on use (Lithium batteries 
recommended for colder environments). If PIR Motion 
Sensor batteries are low Base Station will emit three 
high-pitch beeps every ten minutes. If Base Station 
batteries are low it will emit two high-pitch beeps.

Clear Memory: Press and hold the Learn button on 
the Base Station until 3 beeps are heard. If the PIR 
Motion Sensor signals while Learn button is pressed, 
repeat the procedure.

Programming Additional PIR Motion Sensors: 
Each Base Station can learn the code of up to 8 PIR 
Motion Sensors, responding with multiple buzzes. To 
program additional PIR Motion Sensors see Step 6.

On/Off: To turn Base Station OFF hold down the 
Volume button until a beep is heard and light goes 
out. To turn Base Station ON press the Talk button.
