  • What's Included
  • Turn on your INSTEON-controlled lights or appliances when you enter the room and turn them off after you've left. Truly automating your lighting, this motion sensor is perfect for areas of your home such as the laundry room, closets and the garage where lights commonly get left on. Use this motion sensor for indoor or outdoor applications, and link it to a wall switch, plug-in lamps or appliances. You can even have the motion sensor trigger your thermostat to a favorite comfort level when you enter your home or any room in your house.

    Additional features include an adjustable 'Off' countdown timer delay, night-only mode with adjustable light sensitivity settings, adjustable motion sensitivity, wireless range of up to 150', 40-foot field of vision and a pivoting mounting bracket. INSTEON Wireless Motion sensor is a must-have for any INSTEON home automation network as an addition that will make your life more convenient, fun and energy-efficient. A 9 Volt battery is required and included.

    Please note that 2842-222 is the new product number of 2420M. The product and functionality are the same.

    Required Accessory
    Since the motion sensor only transmits RF signals, your home must have at least one Access Point or other dual-band product to interpret the command for controlling powerline only devices.

    Walk into a room and have the lights turn on automatically
    How It Works
    When the sensor detects motion it sends a wireless RF signal to the nearest Access Point or other dual-band product (sold separately) which in turn relays the signal over your existing power wires to turn on linked devices such as lamps or wall switches. After a selectable time of no motion, the sensor turns those same lights (or appliances) off.

    The motion sensor also features a secondary dusk / dawn control feature that is accessible with computer controllers such as HouseLinc or ISY-99. It allows you to set a device or group of devices to activate when the photocell detects a change in light or dark conditions for more than 3.5 minutes. Great for automatically controlling landscape lighting and more.

    Optional Power Supply
    A Plug-In 9-Volt Power Supply (Battery Eliminator) can be used in place of a 9 Volt battery, eliminating the cost and trouble of regularly replacing the battery. To install, just notch a small hole using a file or shear on the Motion Sensor battery door (for the power supply wire) and plug it in.

    Note About PIR Sensors
    As with all PIR (Passive Infrared) motion sensors, there are certain factors which can cause detection range / reliability to vary. Because PIR sensors rely on changes in heat to detect motion, be aware of the following factors that can effect PIR reliability when choosing a location to mount your INSTEON Motion Sensor:
    • Rapid environmental changes
    • Direct sunlight
    • Direct wind from a heater or A/C
    • Fireplaces

    Also, please note that certain types of treated glass may or may not act as an infrared 'wall' through which a motion sensor can detect. If you want to detect motion through glass, we recommend you test it in your particular application. Note: Any accumulation of ice, snow or dirt on the Fresnel lens may also interfere with the motion sensor's ability to detect motion.


    Never Leave Another Light On Again
    INSTEON Wireless Motion Sensor is a great energy-saver: Your lights will turn on when you enter and automatically turn off after you leave, so you'll never have to worry about leaving your lights on. Also, INSTEON Wireless Motion Sensor has a built-in photocell, so it can be disabled during the day. If daylight is enough to light your house during the day, Motion Sensor can leave the lights off, even when motion is detected. Using Motion Sensor to limit the amount of time lights are on, is a great first step towards saving energy and protecting the environment.

    Unlock More Motion Sensor Options with HouseLinc
    Get HouseLinc and you'll be able to make adjustments to the INSTEON Wireless Motion Sensor without having to touch it again. These adjustments include:
    • Delay
      Change the Off duration to anywhere between 30 seconds up to 2 hours.
    • Indicator Intensity
      Controls the LED indicator brightness. This is good when you have the motion sensor in a bedroom and don't want the distraction of the red LED when it's being activated.
    • Ambient Light
      Adjust the sensitivity of the motion sensors photocell (light sensor). This allows you to set the amount of light the motion sensor is required to see before transmitting a command.

    Dusk / Dawn Photocell Sensor
    Save energy by ensuring lights are off at dawn or turn your porch lights on at dusk with INSTEON Motion Sensor's dusk / dawn feature. When used with supported INSTEON software or an INSTEON automation controller, Motion Sensor can also be used as a dusk/dawn sensor. After it has been bright for 3 and a half minutes, Motion Sensor will send an Off command for its 'Group 2', which can be used to turn off lights and appliances or trigger a software event. Conversely, it will send an On command after it has been dark for 3 and a half minutes.

    Low Battery Warning
    Get notified when it's time to change the battery. INSTEON Motion Sensor has 2 methods of indicating the battery life is low:
    • LED double-flashes after motion is detected (even if LED is disabled)
    • On command is sent to 'Group 3', which can be utilized with INSTEON software or an INSTEON automation controller

    For extended battery life, consider purchasing a 9V Lithium battery which can extend battery life by 4 times.

    If you have a need for the motion sensor to activate many links, using HouseLinc, ISY-99 or other INSTEON computer controller that supports this product can extend battery life.

    Motion Sensor has been manufactured with a surface that can be painted to blend in with your home decor. This gives you the ability to decide exactly what color will give your motion sensor installation that professional finished look. Please note, it is recommended that you protect the Fresnel lens during the painting process. Any excess paint or residue may cause motion sensor to operate improperly.

    Review of 2842-222

    Works great. I wish there was more control over sensitivity (One of my applications needs less sensitivity).

    Review of 2842-222

    These motion sensors work well. The only thing I couldn't get to work reliably is the day/night sensor setting. I tried setting the threshold off the internal potentiometer to no available. Even working with Insteon tech support I couldn't find a setting that worked reliably. Eventually I gave up and bought an ISY and used the suppression rules to replace the day/night functionality.

    Other than this, these motion sensors work great. I have several and like them.

    Review of 2842-222

    This is by and large the most useful of the Insteon product line. Half of the automation out there could not be done without using this coupled with a controller to function as a energy saving device, a low light detection device and a timer. The product functions as it should however it should be noted that these motion sensors are not necessarily pet friendly. While there's a way to modify the sensor beam (abc) great care needs to be performed to aim the sensors where a pet will not trip them unless you like the lights coming on anytime they walk by throughout the day/night even if you're not there. It would be nice if the batteries lasted longer as they're difficult to change. There should be a mini motion sensor version created to reflect the change in technology as these haven't changed size in several years, almost as far back as the x-10 erra. What would be nice is if the motion sensors could act as a range finder to identify an object's location relative to the sensor to allow for more fine tuned control.

    Review of 2842-222

    I'm having set up problems I believe it's operator error though. The rest of my insteon products I've purchased are stellar. Best home improvement investment I've made in along time. Only complaint is more detailed user manual simpler more straight forward description how setting will affect it's control. Also a ulster manual for the hub Mobil app for iPhone

    Review of 2842-222

    Have used multiple units for years with excellent results. I do have one finding not reflected in the other reviews. Battery life. When the detector stops working, replacing the battery almost always restores function. However testing the used batteries indicates they are still good/useable actually about 8.7 volts on meter. 9V batteries are too expensive to discard with useable life.
    Solution: Solid state components are designed to operate over a range of power requirements. 9 volts is commonly used because the battery package is more compact and convenient. 12 volts while more bulky is more efficient and provides greater battery life in marginal 9 volt applications.
    Parts: Butler PM-60 pill bottle $.75 from my veterinarian for outside operation, Radio Shack Battery Holder 270-407 $2.99, Radio Shack 9V snap connector 270-235 2ea $2.99/5pk, 8 AA Alkaline Batteries. wire insulation I use two section clipped from a 12 Way 10A Electrical Screw Terminal Connector 2 pin.
    Assembly: Pierce bottle cap with awl. Thread connector wire through hole with connector outside bottle. Attach and insulate connectors observing wire polarity red to black. Remove 9V battery and route outside connector into battery compartment and join connectors minor trimming of one cover retainer may be necessary to improve cover closure and reduce wire insulation compression. Insert 8 AA batteries into holder. Connect inside 9V connector to holder. Insert holder into bottle connector first. Place cap on bottle. Test detector operation. Secure bottle to/near motion detector method optional. For outside operation, mount with bottle cap and battery compartment down.
