Watt Stopper Isole Power Strip

Watt Stopper® surge protectors are part of PSU's energy conservation program.

EDBA and URBN pilot study

Workstations in EDBA and URBN are equipt with surge protectors as of fall 2010. These buildings were chosen because they have energy meters to measure the effectiveness of energy conservation efforts, and because many of the departments within these buildings have an emphasis on sustainability and the effective use and distribution of resources. This is a joint project of FAP, OIT, and the Campus Sustainability Office.

About the Watt Stopper

The strips have 8 outlets, 6 of which are controlled by a motion sensor.

• Two outlets operate like a normal surge protector, providing power to devices regardless of input from the motion sensor. Computer CPUs (towers), fax machines, and copiers should be plugged into one of these two "uncontrolled" outlets, so they continue to receive power regardless of the motion sensor.
  
• Six of the strip's eight outlets are controlled by the personal motion sensor, meaning devices plugged into those outlets are powered off when the sensor detects no movement for a set period of time. Peripheral desktop devices such as computer monitors, desktop printers, speakers, adding machines, personal lamps, etc. can all draw power even when they are not in use. Plugging these devices into the Watt Stopper® saves energy. In 2009 Oregon DAS employees found that Watt Stoppers save 45-50% of workstation energy use.
  
• These surge protectors save energy and also streamline the shut down process for your desktop devices.

Personal Sensor

1. Try various locations, such as under your desk, to find the best place for your motion sensor. 
2. Attach the mounting plate to the desired location with the double-stick tape provided.
3. Snap the sensor onto the mounting plate.

Note: when determining mounting locations for the sensor, verify the connecting cable from the personal sensor will comfortably reach the cable socket on the power strip. The DI-110 is usually mounted under a desk. However, it can be mounted on any flat surface. People who sit very still, may want to place the sensor above the work surface where the sensor can detect subtle movement, such as typing.

Time Delay Setting:

The personal sensor automatically turns off all controlled devices after a workspace becomes vacant and a pre-set time interval, or a time delay, elapses. The setting is user adjustable. Turning the trim point dial, located on the back of the sensor, clockwise or counterclockwise adjusts the time delay. The range for adjusment is 30 seconds to 30 minutes.

• To adjust to 30 seconds (minimum), turn the dial completely counterclockwise.
• To adjust to 30 minutes (maximum), turn the dial completely clockwise.
• To adjust to 15 minutes, turn the dial half way between its maximum and minimum positions.

Altering Coverage Ranges

The IDP 3050-A package also includes strips of tape, used to mask areas of the sensor lens. Masking the lens allows the user to alter or refine coverage areas.

• To narrow coverage, place tape on the left or right sides of the lens.
  
• To shorten coverage, place tape on the top or bottom of the lens. 

Initial Warm-Up

The personal sensor requires an initial warm-up period of up to two minutes whenever the power strip is turned on. During this time, all connected devices will remain on, regardless or occupancy or the time delay setting.
