  • Cooper Wiring Devices Occupancy Sensors are an excellent choice when choosing energy-efficient and money-saving, automatic lighting or appliance controls. These sensors use the most advanced passive infrared (PIR) technology for detecting the heat emitted from moving bodies as they cross the sensor's field of view. Great for commonly used areas, such as workshops, bathrooms, closets, and hallways, this occupancy sensor will make sure lights are never left on by accident. When the sensor determines the absence of motion for the specified amount of time, it will automatically switch the connected light off. The light's On function can be manually or automatically controlled with its Auto-On/Auto-Off or Manual-On/Auto-Off modes. A LED nightlight is built into the switch and can be turned on/off or dimmed to suit the user's needs. This occupancy switch can be used in single pole (single location switching) applications or 3-way circuits and handles loads up to 1,000 Watts or 1/2HP. Compatible with the most common load types, this switch can be used for incandescent, fluorescent, magnetic low-voltage, electronic low-voltage, CFL, or LED lighting, as well as appliances such as ceiling fans.

    This product is also available in almond, black, gray, ivory, and white, each sold separately.

    Review of 21666LA Review by BRETT
    Review of 21666LA

    I am so far very impressed with this motion activated switch. The price was reasonable, considering that it has a number of features that I have not found on other, more expensive devices. Installation was quick and easy. The included instructions are clear and concise. The device seems well made and attractive, but blends in well with the existing switches without calling undo attention to itself. When adjusting the time delay or daylight sensitivity, the plastic cover snaps off easily without the need for tools, and a small phillips screwdriver is used to make the actual adjustments.

    The device is very sensitive, and can detect motion up to nearly 180 degrees in the sensor's field of view. However, detection does not extend much above or below the sensor, which is a good thing if you have pets that might otherwise trigger the light in the middle of the night.

    The device works fine even with flourescent lights, which can pose a problem for some devices. Only a small click is heard when the switch is activated.

    Once the light comes on, it will stay on as long as motion is detected. This means I can set the time delay for 5 seconds, and the light will turn off 5 seconds after I exit the room, but not before. Other switches (X10) will kill the light after the time-out period even if someone is still in the room.

    I would have given this product five stars, except for two minor issues. First, the daylight adjustment -- which prevents the light from coming on during the day -- is a bit tricky to set and is kind of touchy. But once you get it set properly, you don't need to worry about it again. The second issue is the three-way operation. Even though I connected the traveler wire according to the instructions, the other switch seems to have no effect on the light. But since the motion detector works so well, this isn't a serious problem.

    All in all, I am very happy with this device and consider it a good value for the price.

    I have these in my laundry room in the basement and in our middle bathroom. The light comes on and stays on while I load my clothes and I comeback to fold them it comes on again. Very helpful and efficient when my arms are full of clothes.
