Frequently Asked Questions - CWA2000 CHAMBERLAIN

What is the detection range of the Chamberlain CWA2000?

The CWA2000 can detect motion up to 40 feet (12 meters) with a 110-degree detection angle.

What voltage does the CWA2000 require?

It operates on 12-24 V AC or DC power, suitable for most control systems.

Can the sensitivity be adjusted?

Yes, the CWA2000 has an adjustable sensitivity control to reduce false triggers from small animals or moving foliage.

Is the CWA2000 weatherproof?

It has an IP54 rating, meaning it is splash-proof and can withstand rain and dust, but should not be submerged.

How do I mount the CWA2000?

Mount it on a wall or ceiling using the included bracket. Ensure it is 6-8 feet high and pointed away from heat sources.

What is the time delay setting?

The output relay can be set to stay activated for 5 seconds to 30 minutes after motion is detected.

Can I use the CWA2000 with other brands?

While designed for Chamberlain systems, it can work with any device that accepts a dry contact relay output (1A @ 30V).

Why does my CWA2000 activate when there is no movement?

Check for heat sources like heaters or sunlight hitting the sensor. Also reduce sensitivity or adjust the mounting angle.

Does the CWA2000 have a test mode?

Yes, most Chamberlain motion detectors have a walk test mode that disables the time delay for immediate feedback during installation.

What is the warranty on the CWA2000?

Chamberlain offers a 2-year limited warranty covering defects in materials and workmanship.

USER MANUAL CWA2000 CHAMBERLAIN

The Wireless Motion Detection System uses a Passive Infra-Red (PIR) Motion Sensor to detect movement of people and vehicles.

The Base Station is powered by the DC adapter and the 4 AA batteries supply power in case of a power outage.

NOTE: The Base Station is intended for indoor use only.

WARNING: This product can expose you to chemicals including lead, which are known to the State of California to cause cancer or birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov

Operation and Features

BASE STATION Antenna Volume On/Off Button

On/Off: To turn the Base Station on and off, hold down the power button until you hear the on/off tone.

Volume: The Base Station is equipped with adjustable volume controls. The lowest volume setting is the mute feature.

Batteries: If the Base Station batteries are low, the Base Station will beep every 30 minutes. The AA batteries in the Motion Sensor will last up to 2 years depending on use (Lithium batteries are recommended for colder environments). If the Motion Sensor batteries are low, the Base Station will beep every 30 minutes until the batteries are replaced. The Motion Sensor will continue to operate with a low battery, however the light will not illuminate. For peak performance, inspect batteries annually and replace as needed.

Programming Additional Motion Sensors: The Base Station can learn the code of up to 7 additional Motion Sensors, responding with unique buzzes. To program additional Motion Sensors see Step 4.

To order additional Motion Sensors call 1-800-528-9131.

Clear Memory: Press and hold the Learn Button on the Base Station until 3 beeps are heard.

Assembly and Programming

1

Attach Motion Sensor box to mounting plate with large silver screw. Tighten screw until Motion Sensor stays in place when repositioned.

Plug in the Base Station. Adhere rubber pads to the bottom of the base.

DC Adapter Input

4 AA batteries are optional in case of a power failure.

OPTIONAL

4

A Ensure Base Station and Motion Sensor are in close proximity to each other. Press and release Learn Button on Base Station. Buzzer will sound.
B Within 60 seconds, press the Learn Button on the inside of the Motion Sensor. LED light will illuminate and Base Station will buzz.

5

Insert battery pack facing away from circuit board and fasten cover with the smallest screws (provided).

NOTE: Ensure the batteries do not touch the circuit board and the antenna and battery wires are not pinched.

6

Test Motion Sensor by waving hand in front of sensor. LED light should flash and the Base Station will buzz X number of times indicating which sensor has been activated.

MOTION SENSOR INSTALLATION

7

Mount Motion Sensor horizontally on solid surface 3-5 feet (1-1.5 m) off the ground and within 1/2 mile (0.8 km) of Base Station (rotate sensor to access screw holes). Unit should be able to swivel as needed.

Attach sun/rain shield. NOTE: Keep Motion Sensor antenna away from metal objects. Do not mount Motion Sensor in direct sunlight, near moving tree branches, or in the path of a sprinkler system.

Vehicle Alert Installation: For cars, the best mounting position is about 4 feet (1.2 m) high, between 10-20 feet (3-6 m) back, and angled to see the back of car after passing the sensor.

10-20 feet (3-6 m) 4 feet (1.2 m)

The Motion Sensor lights up, but the Base Station does not respond.

The Motion Sensor must be programmed to Base Station (See Step 4). Ensure Base Station is on and the volume is turned up.

Motion Sensor is detecting motion only part of the time.

Ensure the Motion Sensor is set to the High Sensitivity setting (See Step 2). To detect cars, it is best to mount Motion Sensor at height of car's motor and have it between 10-20 feet (3-6 m) from the road. Swivel sensor as needed.

The Wireless Motion Detection System is giving false alarms.

Check for moving tree branches or insects in sensor window. 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.

It is possible that condensation has built up on the sensor. Wipe condensation from Motion Sensor with cotton swab. Let it sit inside for a few hours, open to the air, without the batteries and it should correct itself.

Check Sensor Switches on Motion Sensor. See Switch Settings.

Base Station beeps every 30 minutes.

The batteries in the Base Station or the Motion Sensor(s) are low. Replace the 4 AA batteries. Check the Motion Sensor(s), if the LED illuminates on all of the Motion Sensors, change the batteries in the Base Station.

The Wireless Motion Detection System is not getting expected transmission range.

Keep both antennas vertical and keep Motion Sensor antenna away from trees and metal objects. Ensure Base Station is in clearest possible sight of the Motion Sensor. The less objects between the devices, the longer the range.
