Energy-Saving Sensor & Switcher Division
Why do we need energy controls?
- Typically up to 40% of a building’s electrical usage is lighting.
- Uncontrolled buildings experience tremendous amounts of energy waste.
- Buildings with uncontrolled lighting experience huge energy wastes:
- Lighting and/or HVAC systems for entire floors remain ON when only one or no occupants are present.
Wattstopper/Legrand founded by two brothers in California in 1984, become a ISO certified and joined the Legrand group in 1996. In the years that followed, WattStopper expanded its occupancy sensor product offering, as well as developing control solutions using other technologies. Today, WattStopper offers a comprehensive range of control solutions for commercial applications, including digital lighting management, lighting control panel systems, occupancy sensors, daylighting controls, fixture sensors and controls, wireless lighting controls and plug load controls.
An industry leader, WattStopper draws upon its rich heritage of innovation exemplified by a few highlights:
dual technology occupancy sensor in market since year 1991

In 2009, Alton sees the world addresses environment pollutions are getting more concern, and acts with the urgency that needed to meet the challenges of the urbanization for children’s’ children by doing a portion in the business to reduce pollution – In September 2009, Alton becomes a distributor for Wattstopper/Legrand, a manufacturer for energy-saving by lighting controls.

In most cases, the control strategy will include automatic operation of the lighting, taking into account the needs of the space’s occupants and what might be necessary to comply with mandatory energy codes. Further control strategy decisions will involve what devices will be employed to satisfy those needs.
Control technologies, on the other hand, usually refer to the type of device that will be used to carry out a specific strategy and what method the device will use to operate (passive infrared, ultrasonic or dual technology sensors, timers, daylighting controllers or lighting control panels.
An occupancy sensor is an energy conservation device designed to detect the presence of human occupants in a given area and sending signals ON
or OFF to one or more electrical appliances. Sensors have proven to be dramatically effective at eliminating energy waste.
|means no adjustments are needed installation. SmartSet monitors the space to identify usage patterns. Then it automatically adjust the time delay and sensitivity settings for energy efficiency.|
|the light don't need to stay ON for the entire length fo the time delay, if a brief visit such as someone is just dropping mail. A "walk-through" mode can turn light OFF after 3 minutes, if no activity is detected after 30 seconds of an initial occupancy detection. If motion continues beyond the first 30 seconds, the selected time delay applies.|
|many occupancy sensor contain a built-in light level sensor with rotary switch. Our selected new generation sensors incorporate this feature PLUS a unique one-touch set up.|
|our sensors available in 230VAC or 24VDC voltage operated to match each and every application and installation style.|
|built-in switch to bypass the light level and occupancy detection control function to allow lights to be manually controlled.|
|simplifies sensor adjustments and obtain accuracy setting value, that surpass many sensors with rotary switch setting which result inaccurate value and hassle commissioning.|
|incorporated circuitry that reduce stress on sensor relay and increased sensor lfe.|
Photosensor or Daylighting controls transform a daylit area into an energy-saving opportunity. Estimates that potential energy savings from utilizing such devices can exceed 40%. Since peak electrical load patterns tend to parrallel periods of the most plentiful daylight, controlling the electric lights in response to the presense of daylight can painlessly reduce peak load.
