The CS350N Passive Infrared (PIR) Dual Relay Vacancy Sensor provides automatic lighting shutoff for applications that require separate switching of two loads. It is engineered to comply with Californias Title 24 2008 residential energy code. The CS350N operates as a manual on sensor. Users must press one or both of the on and off pushbuttons to turn on the connected loads. The CS350N employs PIR technology to sense the difference between the infrared energy from a person in motion and the background space. It keeps the loads on as long as motion is detected and provides automatic shutoff, following a user selected time delay, when motion is no longer detected. Users may turn the connected loads off manually.
